0002                           Introduction

-------------------------------------------------------------------------------
===============================================================================

The game of Half-Life was probably the best FPS of its time. It was one of the
few to have a simple and interesting plot, even though it was not a very large
one.  It has in game cut-scenes so that a plot twist can take place without
your ever leaving the controls.  This allows you to simply wisk through the
area if you don\'t care for the plot or already know it.

You do not always have to go by the guide that I have written.  If you prefer
to go another route or do a little exploring then by all means, do so.  I have
just written one way to go about things, beat the Nihalinth with a crowbar, I
don\'t care.  This is just to help you along in those places where you may get
stuck.

Feel free to contact me if you have questions about the game, want to suggest
some strategies for a part in the game, or wish to point out any errors that I
have made in the FAQ.  If you submit a strategy I will be glad to put in my
guide and I will give you credit.  I hope this is helpful.

Wow, this turned out to be shorter than expected.  Oh well, it doesn\'t matter.
I doubt anybody will read this Intro anyway.

0003                           Game Overview

===============================================================================

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
0003.1                             STORY
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------

Deep in the bowels of the Black Mesa Federal Research Facility, a decommissioned
missile base, a top secret project is underway. A portal has been opened to
another dimension, and human science has never seen anything like the world on
the other side.

You are Gordon Freeman, a young research associate in the Anomalous Materials
Laboratory. You have limited security clearance and no real idea of just how
dangerous your job has become, until the morning you are sent alone into the
Test Chamber to analyze of a strange crystalline specimen. A routine analysis,
they tell you. Until something goes wrong.

Is it sabotage? An accident? Or is it something you did? All you hear is
screaming; all you see is space-time shattering. The next thing you know, the
entire Black Mesa Facility is a nightmare zone, with sirens wailing and
scientists fleeing in terror from the things their co-workers have become.

Hordes of creatures from the far side of the portal are pouring through rifts
in the local fabric of reality. Monsters are everywhere. Madness rules. You
head for the surface, but the usual routes are impassable-closed off by the
disaster, infested with headcrabs and houndeyes and increasingly larger and
hungrier creatures.

As Gordon Freeman, you must enlist the help of traumatized scientists and
trigger-happy security guards to get through high-security zones, sneaking and
fighting your way through ruined missile silos and Cold War cafeterias,
through darkened air ducts and subterranean railways. When you finally come in
sight of the surface, you realize that the inhuman monsters aren\'t your only
enemies-for the government has sent in ruthless troops and stealthy assassins.
Their orders seem to be that when it comes to the Black Mesa, nothing gets out
alive... and especially not you.

When even your own species turns against you, maybe you\'ll be glad to see
another portal beckoning. But then again, on Earth you have allies; while on
the far side of the portal, nothing at all is familiar except the sense of
danger.

Save the Earth? Well, maybe. But that\'s a pretty low priority compared to
saving your own skin.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
0003.2                      Difficulty Levels
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------

Easy- Enemies will only take a few hits and don\'t do a lot of damage.  As the
name indicates, it is quite easy.  For beginning FPS players.

Medium- Enemies are fairly matched for the most part against you.  They deal
out more damage and you deal out less.  They are tougher to kill.  Not too
hard, but a challenge nonetheless.   For the moderate FPS gamer.

Hard- Enemies will deal out a lot of damage, enemies will take more damage
before they die.  Bosses can be quite difficult at times.  Not for beginning
level FPS players.  Assassins now have a cloaking device, which makes killing
them a real pain in the ass.  Also voltiguants now have halved their charge-up
time for their electricity attack.

0003.4                           Weapons
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------

Crowbar
-------

The crowbar can be used on anything. It is a very powerful weapon for
hand-to-hand combat. It can also be used as a tool. Use it to break through
vents, windows, and wooden planks. The crowbar can be used underwater.

First Sighting: Unforeseen Consequences


9mm Handgun (Glock Pistol)
--------------------------

The 9mm handgun is the weapon of choice for all security guards. It only fires
one bullet at a time and it can have 17 bullets per clip +250 bullets max. 9mm
ammo is shared with the Military Issue Mp5 Semi-Automatic Machine Gun. The 9mm
can be used underwater.

The 9mm is really the most generically useful weapon you have. It works well
in almost every situation. It isn\'t the most powerful weapon, but you do not
have to reload as frequently as some of the other weapons, and it is very easy
to find ammo for.

First Sighting: Unforeseen Consequences


Hand Grenade
------------

The standard hand grenade is probably the most useful of the explosives you
carry. You can hold up to 10 of them at any given time. Each grenade has a
5-second delay.

Grenades are great for one thing: tossing into areas that you cannot see into
and therefore can\'t fire bullets, shells, etc. into. Grenades work great for
clearing out areas around corners and for flushing soldiers out of hiding.
(Soldiers will run when they hear the grenade touch down next to them.)
Remember that grenades bounce off of walls and whatever else you throw them at.
Note that they\'re not like the grenades in some other games that always
instantly explode when they hit an enemy or breakable item; Mp5 grenades serve
that purpose in Half-Life. Therefore, if you cannot reach an area from your
current position, think about bouncing a grenade off of something (or even
someone) to get it to where you want it to go.

First Sighting: Unforeseen Consequences


Shotgun
-------

The double-barrel shotgun is a very powerful weapon, though it is not very
accurate at a distance. It holds 8 bullets per clip +125 bullets max. It is
not water-compatible. (Trying to use it underwater won\'t ruin it or its ammo;
it just won\'t fire.)

The double-barrel shotgun is best used for breaking through barriers quickly.
Use it, for example, in Blast Pit when you want to break through the boarded-up
passageways quickly. The shotgun is also a decent weapon for relatively close
combat. Don\'t plan on sniping with it, though.

First Sighting: Office Complex


Mp5 Semi-Automatic Machine Gun (9mm Assault Rifle)
--------------------------------------------------

The Mp5 is the weapon that most military soldiers carry throughout the game. It
holds 50 bullet clips +250 bullets. Ammunition is shared with the 9mm handgun.
The Mp5 also has a grenade launcher on it. It can hold up to 10 grenades at any
given time. The grenades are not time-detonated. Rather, they detonate when
they hit something -- and never bounce. The Mp5 does not work underwater.

The Mp5 is the best all-around weapon. It is great for sniping from relatively
long distances and it is great for up-close and personal combat. It can be used
for breaking up boxes and triggering set tripmines from far away. Pay attention
to your ammo, though, as you can run through a 50 bullet clip in a very short
amount of time. If you find yourself in a bind and have to reload, launch Mp5
grenades to take care of any nearby attackers while you are reloading (or dodge
and hide if you have sufficient cover).

First Sighting: \"We\'ve Got Hostiles\"


.357 Magnum
-----------

The .357 is a basic pistol. It is very powerful and it usually takes out most
aliens or soldiers in one or two shots, even on Difficult level. It holds 6
bullets internally and fires at a rate of one bullet per mouse-click. The .357
cannot be used underwater.

It takes quite a bit of time to reload the .357. It also produces a strong
kickback when fired. Hence, the .357 is a good choice for single shots and for
still shots, especially if you\'re sneak-shooting an enemy who hasn\'t seen you
yet. As for fighting in combat, the .357 is not the best choice of weapon.

First Sighting: Blast Pit


Laser Tripmine
--------------

The tripmine is basically a trap. You can carry up to 5 tripmines at any given
time. You can only set a tripmine when you are near the surface that you want
to set the mine on.

The tripmine is especially useful for the smarter enemies like soldiers,
assassins, alien slaves, and alien grunts. Any enemy that might chase or search
for you will fall for your trap. Not to say other enemies will not, but
ironically, the smarter the enemy, the more likely they will walk into a
tripmine.

You might also want to use tripmines as controlled explosives. For example,
set a few tripmines on a large metal door that needs to be blown open. Move
far away and target one of them. Shoot it out and all of the tripmines should
detonate, creating a massive explosion.

First Sighting: Blast Pit


C4 Satchel
----------

The C4 satchel is a controlled explosive. You can carry 5 of them at once.
Satchels detonate by a remote control that you carry. You first drop a satchel,
which brings up the remote control. Click again to detonate the satchel. You
can also set up a series of satchels by pressing the secondary attack key after
tossing the first satchel. Pressing the detonator then will blow up all the
ones you threw at once.

The C4 satchel is a very cool trap. It is very powerful. The satchel will
remain dormant until you detonate it, no matter what. It can\'t be blown up by
bullets or other explosives. Also, you don\'t have to have a direct line of
sight in order to detonate it. You could, for example, drop one on an elevator,
send the elevator up, and then detonate it to take care of whatever might be
waiting at the top.

First Sighting: On a Rail


Tranquilizer Crossbow
---------------------

The tranquilizer crossbow accepts 5-dart clips +50 darts max. It can be used
underwater.

The crossbow is the best sniping weapon in the game. Switch into the sniping
option with the secondary attack key to maximize precision. The tranquilizers
will usually take out a soldier or alien slave with one shot, no matter where
you hit them or what difficulty level you\'re playing on. Therefore, a shot in
the foot might down a G.I. more quickly than a shot to the head. Pay close
attention to your ammo, though. There are not that many tranquilizer clips in
the game and it takes quite a while to load darts and even more time to reload
a clip.

Also note that if you load a saved game while the crossbow\'s sniper scope is
on, then it will remain on no matter what weapon you have readied. However,
this can be inconvenient, so either ready the crossbow and hit the secondary
fire button a couple of times, or just quit and rerun the entire game.

First Sighting: Apprehension

Snarks are little aliens that you get to deploy somewhat like grenades. They
run around searching for anything living. Once prey is found, they swarm on it
until they either kill it or expire. You can carry up to 15 snarks.

Snarks are great for disturbing squads of soldiers. Let some run loose in a
military outpost or command center while you\'re hiding nearby and they will do
most of the work. Watch out for snarks yourself, though. Once they are released
they will attack anything, including you. Snarks will expire and explode
after 10 seconds or so.

Experimental Gauss Gun (Tao Cannon)
-----------------------------------

The gauss gun is an experimental weapon that fires a powerful laser that
incinerates whatever it comes in contact with. It is based on
chemical/nuclear-batteries that come in protective boxes. Power is based on
percentage values. Therefore, you have a max of 100 percent power with no
reloading required. Battery power is shared with the experimental egon gun.

The gauss gun is particularly cool because of its particle effects. You can
fire in a rapid-fire mode, which rapidly fires the laser beam at your target,
sending off glowing embers. The power-up mode (hold down the secondary attack
key) is very powerful. It takes about 12 percent of your battery power to fully
power up the gauss gun. A powered-up shot will instantly atomize all but the
most powerful enemies. Be careful, though; if you try to hold the power-up
charge too long without releasing it, the gauss gun will backfire and cause
severe damage to you.

First Sighting: Questionable Ethics


Rocket-Propelled Grenade Launcher (RPG)
---------------------------------------

The RPG works only with single rockets at a time, +5 rockets max. It cannot be
used underwater.

The RPG is probably the coolest and the most powerful weapon in Half-Life. It
has two modes that you can switch between by hitting the secondary fire key.
The first is a straightforward (dumb-fire) launch of a rocket-propelled grenade.
Aim and fire, and no matter where your sights move to, the rocket will hit its
original target.

The other fire mode is a laser-guided launch, where a laser directs the
targeting of the rocket even after it\'s been launched. Hence, if you target a
moving enemy, fire and track the laser sight along the path of the enemy so
that the rocket intercepts him when it gets within range. Be careful of firing
a rocket at something close to you; the explosions can do severe damage. It\'s
because of this and the scarcity of rocket ammo that you should save all of
your rockets for big targets like military helicopters and tanks.

First Sighting: Surface Tension


Hornet Gun (Hivehand)
---------------------

The hornet gun is the standard weapon of alien grunts. The weapon fits over
your hand and is an actual nest of hornets. It holds up to 8 hornets at any
given time and automatically regenerates hornets whenever they run out. In
theory, you have infinite hornets at your disposal.

The hornet gun is especially nice, as the hornets will track their prey around
corners, up stairs, and through doorways. Hornets will also often hit enemies
on the other sides of closed doors and walls. All you have to do is aim them
in your enemy\'s general vicinity and the hornets will do their best to
contribute to your success. The hornets themselves will do quite a bit of
damage when they hit.

The hornet gun\'s secondary attack mode is also useful, since it very quickly
fires hornets in a straight line. It won\'t track enemies, but this mode is
useful for blowing up explosive containers at a distance, and can kill an
enemy more quickly than the regular fire mode can if you fire straight at him.

First Sighting: Surface Tension


Experimental Egon Gun
---------------------

The Egon gun, like its companion the gauss gun, is very powerful. It fires a
concentrated electrical beam at a target. It runs on battery power that can be
collected from small yellow-and-gray containers. Battery power is out of 100%
and there is no need to reload.

The Egon gun is powerful enough to disable entire groupings of enemies.
Anything that runs through or is hit by the beam loses a lot of life. Therefore
if you have quite a swarm around you, grab your Egon gun and start circling.
You receive this weapon late in the game, but there are still several times
when it\'s the best weapon for the job.

0003.5                          Enemies
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------


Headcrabs
---------

Headcrabs are the simplest enemy that will do damage to you. They make an odd
screaming noise and lunge at your head and upper torso. If they are able to
kill their victim, headcrabs will latch on and assume control of the victim\'s
body, effectively turning him into a zombie. Headcrabs are simple to deal with.
Avoid their lunges and drop about 3 shots into their main body to get rid of
them.

One way to kill headcrabs without using any ammo is to strafe out of the way
when they leap at you, then quickly run up to them and whack them with the
crowbar. They can\'t jump backwards or sideways, and it takes them awhile to
turn in place and prepare for another jump.

First Sighting: Unforeseen Consequences


Zombies (Hybrids, Mawmen)
-------------------------

A zombie is the end-product of a head crab�s efforts. Zombies are much more
powerful than headcrabs, but they can never be as fast. Zombies are very slow,
so you can easily out-maneuver them. Their main form of combat is a two-slash
combination attack, which can be very dangerous. Avoid any attacks and aim for
the head. Zombies will usually go down in two or three shots from the shotgun.

To kill a zombie with the crowbar, run up to him and whack him once, then back
off quickly. If he starts his slow two-arm swing attack, move in as soon as he
swings his second arm and get in two or three good whacks before retreating.
If he uses his faster attack, you should only risk one crowbar hit after it.

First Sighting: Unforeseen Consequences


Houndeyes
---------

Houndeyes are small, puppy-like creatures that curiously bounce around you.
Once they get close enough, they will give off a shrill scream and fire a
crippling sonic burst at you. Houndeyes tend to attack in packs. Be careful
not to fall for their rather clever little traps.

Quite often, a single houndeye will approach, maybe fire off a sonic burst,
and then run away. If you chase him, you might find yourself in the good
company of an entire group of houndeyes. Just be on the alert and pay attention
to seemingly simple situations. Houndeyes will usually die after a single
shotgun blast. If a houndeye is powering up his sonic burst, aim for him first.

First Sighting: Unforeseen Consequences


Alien Slaves (Vortigaunts)
--------------------------

Alien slaves are the first real bipedal opponents. They are the first to act
in true squads and are the first to really try to outsmart you. They will run
away from weapon fire, they will hide behind doorways and in shadows, they will
try and draw you into traps, and they will search for you.

They can fight hand-to-hand with a powerful slashing attack, and they have a
very powerful electrical discharge that can quickly cut your health and armor
down. The electrical bolt that they fire requires them to conjure up enough
power before firing. Be sure to target whichever alien slave is furthest into
his power-up. One or two shotgun blasts will usually take care of an alien
slave.

A note for Difficult-level players is that the slaves\' power-up time is cut in
half, allowing them to fire much faster.

First Sighting: Unforeseen Consequences


Bullchickens (Bullsquids)
-------------------------

Bullchickens are probably the most unpredictable creatures you will meet in the
game. They can charge and attack you up close, or they can fire a glob of
corrosive mucus at you from a distance. Sometimes, bullchickens will remain
oblivious to you until you get really close or fire at them. Sometimes they
will just fire their green mucus at you. Other times they will charge you for
no reason other than to spit at you up close or throw you around with their
facial tentacles.

Occasionally, bullchickens will deal with other aliens or humans before getting
to you. Two to three shotgun blasts to the main body mass of a bullchicken
will kill it.

First Sighting: Unforeseen Consequences


Barnacles
---------

Barnacles are the quiet killers. They attach themselves above any route of
travel, be it room or cavern. A long grey tongue hangs down from their toothed
jaws. If an unsuspecting victim stumbles into one of their tongues, the tongue
latches on and drags the victim up and into the jaws of the barnacle. One or
two shotgun blasts to the mouth will kill a barnacle. The tongue does not pose
a threat after the barnacle is dead.

If you do get caught in a barnacle\'s tongue, try to free yourself before you
get pulled up too high. If you do reach the jaws of the barnacle, switch to
the crowbar and start beating the barnacle until he lets go. Hopefully you will
survive the fall. (Remember that falling any distance into any amount of water
never hurts you.)

First Sighting: Unforeseen Consequences


Military Turrets
----------------

These are automated target-seeking machines that the military has set around
for automated defense. They can\'t walk around, but they can swivel 360 degrees.
hey start out dormant, but activate and scan for targets when you (or someone
else) walk through their red laser alarm beam, brush up against them, or start
damaging them.

The best way to take one of these things out is to shoot it in the leg or in
the top of its \"head\" while keeping something solid between you and it so that
it can\'t shoot you. Bouncing a grenade around a corner also works well.

First Sighting: \"We\'ve Got Hostiles\"


Soldiers (Marines, Grunts)
--------------------------

Soldiers are the most versatile enemies in the game. They can have a variety
of weapons. Generally, soldiers carry Mp5\'s and standard issue grenades. Some
soldiers carry shotguns and some carry Mp5 grenades in addition to their Mp5
machine gun. Occasionally, soldiers will have special or mounted weapons such
as rocket launching platforms; high-powered, floor-mounted machine-guns; and
firebombs.

Soldiers will always work in squads. They will cover vast amounts of terrain
looking for you. They know where to look and how to sneak up on you. Once they
find you, they will work to out-flank you by breaking apart into two groups,
to flush you out of hiding by banking grenades around corners, and to get into
those hard to reach areas by rapelling out of helicopters. Soldiers will duck
in and out of cover and they will watch, listen, and react to anything that
occurs. They make for some very interesting opponents.

You tend to have much more health than the average soldier does, so you will
almost always win a face-to-face firefight against a single soldier. Be careful
when you are dealing with entire squads, though. Always concentrate fire on a
single soldier until he goes down. Don\'t try spraying the entire squad; you
will waste a lot of ammo and only do a little damage. Any weapon will work,
but the Mp5 will generally be the best bet, as it takes a bit of fire power to
kill a soldier, and you want to do so quickly.

First Sighting: \"We\'ve Got Hostiles\"


Giant Tentacles
---------------

Giant tentacles are one of the most dangerous enemies you will meet. They have
very sharp \"beaks\" that they pierce flesh with. They attack anything living or
moving in their respective areas. The only advantages that you have are that
they\'re rooted to one spot and that they can only hear their prey nearby; they
can\'t see.

Hence, moving past tentacles is just a matter of staying quiet. Use the walk
modifier or crouch-walk to avoid detection. Toss grenades to distract the
tentacles away from you. Conventional weapons will only make tentacles sink
into the ground very briefly. You need to find an alternate method to destroy
tentacles permanently in the one case where you have to destroy a tentacle to
progress in the game.

First Sighting: Blast Pit


Gargantuas
----------

Gargantuas are huge, powerful aliens that are almost solid armor. They mainly
fire pyrotechnic bolts at you. These bolts will quickly eat away at your
health, so don\'t go close to one unless you have to. Also watch out for the
red globs of energy that gargantuas can fire at you from a distance.

Gargantuas do not react to generic weapon fire except to become angrier. You
can blow up a Gargantua with hand grenades if you have enough, but it takes 9
or 10 even on Easy difficulty. You basically need to dodge gargantuas until
you can find an alternate method of destroying them.

First Sighting: Power Up


Larvae (Hagworms, Leeches)
--------------------------

Larvae are a very basic form of alien, and look like small wriggly worms. They
reside solely in water and they tend to attack in small swarms. A single
crowbar swipe will destroy a larva. You do not have to worry too much about
larvae except when they swarm on you.

First Sighting: Power Up


Ichthyosaurs
------------

Ichthyosaurs are very much like sharks. They reside solely in water, though
they tend to skim the surface as they pace around their environment.
Ichthyosaurs attack with their jaws, but not until they circle you at least
once. Once they hit you, you will become disoriented, so try not to let them
get close.

You can kill an ichthyosaur from safely on shore by firing at it with your Mp5,
shotgun, or whatever whenever you see it swimming on the surface. If you ever
have to kill one while in the water with it, use the crossbow, as it was made
for that sort of thing. If the ichthyosaur is a considerable distance from you,
use the targeting sight and fire a bit below the beast (a necessary adjustment
when sniping underwater).

First Sighting: Apprehension


Military Assassins
------------------

Military assassins can be very difficult. They are quite stealthy, quick, and
precise. They will usually see you before you see them. You will never be able
to get close enough to them to fight up close. They will back flip out of your
reach the second you try it.

Instead of chasing after them, find some relative cover and listen for their
footsteps. Wait for them to approach and then fire an Mp5 grenade or just fire
at them until they go down. Watch for the flash of light given off by their
weapons in order to locate them in darker areas. You will only have to deal
with assassins twice in the game, but they can be very quick and agile, making
them very difficult to kill.

Note that on Difficult level, assassins have a cloaking device they can use to
make them even harder to track.

First Sighting: Apprehension


Alien Grunts (Xen Soldiers)
---------------------------

Alien grunts are the powerhouse alien fighters. They carry hornet guns that
they put to good use firing around corners and up stairwells. Alien grunts are
very powerful creatures, and it takes quite a bit to take one out.

Aim for the head of an alien grunt to maximize damage. They wear body armor on
most of their body that protects them from damage. Alien grunts work in squads
and are excellent trackers. They will search you out and find you once they
know you are nearby. Listen for their footsteps to help you figure out exactly
where they are.

First Sighting: Questionable Ethics


Alien Controllers (Xen Masters)
-------------------------------

Alien controllers are perhaps the most annoying aliens you will meet. They
attack in swarms, flying around and unleashing strings of glowing orbs that
can do a bit of damage. Try to keep track of where the controllers actually
are. This can be difficult, as the glowing orbs can block your view and
disorient you.

Try to concentrate on one controller at a time rather than worrying about all
of the controllers around you. Work on weakening the swarm of controllers
until you have defeated them entirely. Any weapon works well, but the Mp5 is
very useful in taking them out since it\'s usually easy to follow their flight
path with it and riddle them with bullets. The Egon gun can be even more
effective with large groups of controllers that you have to take down fast.

and other factors.

0004.1      Anomalous Materials
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------

When you begin you will start out in a tram car.  This will take you past
various locations in the Black Mesa facility.  Eventually it will stop and a
security guard will come to open the door for you.  Exit the tram and wait at
the door for the security guard to open it for you.  Go past the security
desk where you find out that you are needed for some type of experiment.
Anyway follow the green line on the wall to the locker room where you can get
your Hazardous Environment Suit, HEV.  Press the middle button on the control
panel in front of it to open the chamber.  In the locker room you can open
the locker that says Freeman. Get the power module and go out of the locker
room and follow the green line until you see the blue line.  Follow that to a
door where a security guard will open the door for you. Follow the blue line
on either side and get into the elevator.

Follow the corridor until you see a group of scientists.  They will talk to
you for a moment about the experiment.  Eventually one of them will walk over
to the other door and use the retinal scanner to allow you access to the next
corridor.  Follow it until you get to an elevator and eventually you will get
to a small room.  The scientists will talk to you again and give you some more
information.  You will be handling a rare and very unstable \"sample\".  Oh,
don\'t worry \"nothing will go wrong.\"  Well...not really.

Enter the chamber and follow the instructions of the scientists.  Climb up
the ladder and press the button on the control panel to start the \"anti-mass
spectrometer\".  Go back down and wait by the cage for the sample to arrive.
Uh-oh there is a small discrepancy in the system, you know what happens next.
Well, push the sample into the beam and let the shit hit the fan.  You will
see some freaky scenes (well, maybe I\'m just a wuss...okay I am!) with aliens
but you better get used to it, you\'re going to see a lot of them for the rest
of the game.

Exit the test chamber to find the facility in disarray.  Shed a tear for the
fallen heroes if you wish.  Now retrace your steps back until you get to a
room that overlooks the test chamber, the one in which the scientists talked
to you.  Now wait until a green beam crashes through the window and then duck
under it or run past between bursts.  Follow the path until you get to an
elevator door  get your first weapon of the game, the crowbar.  Now open the
door and watch the people in the elevator plunge to their deaths.  Climb down
the ladder and get the power pack.  Climb back up and go all the way up where
you will see a Barney fighting an alien.  Use the crowbar to smash the alien
and get the pistol from the fallen Barney if he died, if he didn\'t smash him
a few times and he will drop it.

Walk up the corridor and you will see an alien walking at you.  Use either
the crowbar or the pistol, but the crowbar is the best course of action as it
uses no ammo.  If you want to go back to the locker room there is pistol ammo
and a power pack.  Go to the security desk.  You will see a small hole  on
the wall, crawl through it and kill the two headcrabs.  Jump up onto the
angled platform on the other side of the room and crawl through the small
duct.  Get out your pistol and shoot the bullhounds as they come at you.  Go
to the left and you will find two more bullhounds.  The room they came out of
has a first aid station.

Go forward and open the door to the right.  There is a headcrab here.  Follow
his until you come to a ladder, go up until you can just see over the edge.
See those silver cylinders?  Guess what they do...that\'s right they explode!
Fire a bullet into one of them to trigger the explosion, that will kill
anything in the room.  Go to the right once you get off the ladder and get the
scientist to follow you.  Go on the walkways until you see another explosive
cylinder fire a bullet at the creature near the back of the room to make him
stand up, now you can either empty your clip into him or you can wait for him
to get near the explosive cylinder  and fire a bullet into it.  But make sure
that you are standing as far away from it as possible.  Anyway, let the
scientist open the door with the retinal scanner and get all the ammo inside.
Use the first aid station if you need to.

Retrace your steps out of the room and go back to where you were when you
killed the bull hounds, go farther into the corridor.  You should hear the
sound of something being teleported to a location near you, if you wait a
while you can shoot the vile creature but if you move quickly enough you won\'t
have to use your ammo.  When you near a dumpster you should see a scientist
poking his head out of it.  Behind the dumpster is a first aid station.  See
the small hole in the floor near the barred section?  Yes, of course you do.

Look down into the hole and shoot the headcrab.  Now look past the bars and
there should be another alien there, shoot him so that you won\'t have to deal
with him later.  Anyway drop down and now the directions that I give you
correspond to how they would be if you had dropped down facing the bars.  Go
left, right, right, right, left, left.  See the small wheel? turn it and the
tunnels will fill with water.  Now turn around and find a small hole in the
roof, make sure it isn\'t the one you just entered.  When you come out you
should be on the other side of the bars.

Follow the tunnel until you get into a large room, go up the walkways and you
should see a lever.  Press it and the lift should tart moving, go down and
jump onto the elevator before it gets too far below you.  Wait until it gets
near the bottom. Fight off the headcrabs as they come down, most will fall off
but some will stay, so get out your crowbar and waste them.  When it gets near
the bottom throw a grenade down there to kill most of the headcrabs.  Use the
crowbar to kill anything that remains.  Thee is a first aid station to the right
of the elevator.  Break open the boxes to find some ammo.  Follow the path to
the catwalk and stop just before you get on it.  An alien will spawn destroying
the bridge.  You will have to find another way around.  Look to the right and
jump onto the pipes.

Follow the pipes until you see a small vent opening on the right.  Smash it
open with the crowbar and follow it to the SECOND opening in the floor.  Smash
it and smash open the crates for several power cells.  Open the door and go down
the ladder.  Open the door take out any aliens around.  Jump into the sewage
canal and swim to the left.  Follow it until you end up by a first aid station.
Use it if you need to.  Open the door and open the next door.  Follow the
passage to a large room with hanging crates.

Climb up the ladders and hop onto the first crate.  Hop from crate to crate
until you get to the end.  I suggest that you quick-save after you land on each
one.  Follow the path corridor to a door, open it and follow that corridor to
a ladder.  Climb it and follow that to another door.  Open it and you should
find yourself on the other side of the large gap. follow the corridor to an
elevator.  Get on and start it.

-------------------------------------------------------------------------------

0004.3        Office Complex
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------

Get out of the elevator and you will meet a gruesome scene.  There is a
scientist being eaten by a creature in the ceiling and an electrical wire is
sending body parts flying.  To the left of the elevator is a couple of headcrabs,
shoot them and break open the vent on the right.  Enter it and go to the right.
Break open the cover and enter the room.  Be careful not to stray near the
barnacles.  There is a power switch in the small room. Open it and shut the
power off.

Exit the room through the doors and go past where you first broke into the
vent.  Follow the hallway until you get to an area with a lot of boxes.  Break
through them to get to the other side.  There is a headcrab just past the last
box, be careful.  Grab the shotgun from the case and walk towards the Barney.
A monster will attack him, help him and he will let you in once the monster is
dead.  Grab all the ammo you can and get the med pack and power cell from the
area below.  Get Barney to follow you.  Head back and you should see a small
room with water on the floor.

Enter the room and quickly get to the other side on the left to the power
switch to stop the electrical current.  Use the first aid station if you need
to and bash open the vent.  Some headcrabs will come through, kill them and
enter the vent.  Crawl under the fan.  When you come out you will fall through
the ceiling.  Open the door so that barney can come through and help you with
the headcrabs.  Push the crates together so that you can jump up onto a ladder.
Get onto the  platform and you should fall through the roof to another level
just below.  Kill the headcrab.  Follow the vent to the end but don\'t just yet
enter the room.  You will see a gun of some sort slaughter everything in the
room.  Wait until all is dead and wait until you hear the sound of a machine
retracting.  Quickly exit the vent and duck behind a box.  Stay crouched and
push the box to the end of the room and you should see a small switch.  Pull it
and the gun should stop.  Go into the small room at the back and get ammo for
the pistol and the shotgun.

Toss a grenade into the hallway to kill a group of about seven headcrabs. Go up
the stairs.  Get Barney to follow you, get out your shotgun and be prepared to
kill fast.  This area is infested with voltigores.  Quickly go through and
blast them quickly.  Some will spawn in different areas and you will have to
reload several times.  Make sure that you take cover when you do this or else
you will die quite quickly.  Try to use double shots this will kill them with a
direct hit.  There is a first aid station midway through and a health pack on a
desk.  When you exit there will be another health station by the scientist.
Be sure to go around or shoot the barnacle.

Go up the stairs and run all the way up.  Stop beneath the sentry gun and
reload if you need to.  Kill the madman in the hallway and reload again, there
are two voltigores here.  Reload again and continue on.  Kill the Mawmen and
enter the door, use the first aid station of you need to.  Get the security guard
to follow you and go into the door here.  Have Barney shoot the headcrabs that
fall through the ceiling.  Smash the wooden planks that are across the doorway
and kill the Mawmen and go into the freezer room.  Go through and kill all the
enemies.  Get the ammo and somewhere you should find a switch with a red light.
Use it this will start a platform moving overhead.

Go back into where you first entered and climb up the ladder.  Do a duck jump
into the vent shaft after you have smashed the cover.  Follow it until you get
to an edge by the area where the platform is crossing.  Wait for it to move in
front of you and quickly step on.  Smash the crates on it and collect the power
cells.  Get into the vent on the other side.  Follow this until you get to a
room with vents and barnacles all over the place.  Make your way up and be
careful not to fall within the clutches of any barnacles.  One shotgun blast to
the mouth on each will do, to be safe.

Get into the vent and follow it until you get to another vent covering, you
should see a 2 Barney\'s and a scientist, get out of the vent and turn to where
the scientist ran, see the mawman coming around the corner?   Well, shoot it
already!  Go through the door.  Wait a minute...I was just here!  Yes, you
were.  Follow the passages to a place with a fan.  Climb up the ladder and wait
for the fan to turn to a place where one of the blades has broken off.  Jump
through to the other side.

Now follow the corridors until you get to a room where a zombie is trying to
break through the glass above the floor.   A scientist should jump through the
window.  Kill the zombies and proceed to collect the ammo in the two rooms.
Now go to the open elevator shaft.  Jump across to the ladder and climb up all
the way until you are on top of an elevator car.  Break the panel on the top
and jump in, press the button to open the doors.


-------------------------------------------------------------------------------

0004.4        We\'ve got hostiles
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------

When the doors open you will see a scientist frantically trying to reach the
security guard in the other room, but he will get attacked by a madman.  Ignore
the scientist and he will go get himself killed, which is to your benefit,
although it seems sick to say.  For now just charge up your suit and health
and proceed to where the scientist was killed.

Run through the trip wires and quickly duck behind a box.  Kill the two
headcrabs that spawn and then push the box so that you can get close to the
turret without getting harmed.  Jump out from behind it and quickly pump a
shotgun shell into the top part of it.  Now break open the boxes if you wish
for a power cell.  Head crabs will spawn one at a time so get out of here
before you waste a lot of ammo.

Jump over the tripmine and crouch under the next one.  Kill the two voltiguants
and recharge your health if you need to.  Proceed down the hall.  Use grenades
to take out the next two turrets.  Throw one right between them for maximum
efficiency.  Now there are two turrets on the other side of the green crates.
You can get one trough a crack with a double blast from the shotgun.  The other
is taken care of with a grenade toss over the crates.  Now break the glass on
the blast door, as headcrabs will spawn near you and thus saving you ammo as
they get caught on the other side.  Now jump over the crates and slowly proceed
over the floor because the floor is wet.  Now as you come around the corner
issue two double blasts from the shotgun into the turrets, on each.

Use the health station if you need to and now proceed into the next room.  A
scientist will run to the marine and the marine will attack the scientist.
Well, that wasn\'t polite!  Anyway he will attack you too as you are a scientist
too.  So dispatch him with the shotgun and grab his ammo and gun, get on the
elevator and turn around.  More marines will attack you when you come out so
quickly dispatch them all and proceed through to the next corridor, near the
top.  There is also a health station on the top level, use it if you need to.

This next room is also swarming with marines so kill them all and proceed.
These marines will use grenades a lot so be extra careful.  Use the health
station and get on the elevator labeled \"Surface Access\".  Now you will hear
explosions and there is a helicopter flying around, from which many marines
are descending.  Run to the bunker in the center of the area killing any
marines that you may encounter, get on the ladder and climb down.

Get whatever you need from the HEV and health stations and go out the door here
two marines will rappel into the shaft and fire at you.  Kill them and go down
the ladders to the big vent shaft at the bottom.  Enter it and you will find a
large fan at the end.  The first and second shafts don\'t contain much only some
ammo and a health station and they also threw in a headcrab just for fun in the
first one.  Unless you need ammo or health drop down on the right side,
diagonally from where the ladder is.  Enter the shaft on the bottom and proceed
forward, you will find that you did a complete circle from where this part
started.  Anyway listen to the scientist\'s advice and open the silo access door
Get anything that is left from the HEV and health stations and proceed down the
hall.

0004.5        Blast Pit
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------

Smash your way past the crates and you will find a bullsquid and two headcrabs,
kill them all and proceed into the small control center at the top of the ramp,
a headcrab will come at you from behind here so watch out.  Push the lever and
look to your right.  A mawman is breaking through the steel door, give him a
double blast in the chest with the shotgun and go down to the elevator that
you activated earlier.  Get on and push the button to move it.

Get on the rail car and activate it by pressing the USE button and then
accelerate by pressing W up to 4 times for different speeds.  Crouch and stay
behind the control panel until you are accelerating towards a concrete stop.
When your tram hits it you will be flung out towards a group of boxes.  Try to
land on one of them in order to prevent a loss of life from the toxic waste
pool.  Kill the bullsquid shooting at you and jump towards the other side of
the pool.  Climb the ladder and get into the pipe.  Follow it to another
opening.  Duck-jump out and shoot the bullsquid here.  Take the top pipe and
jump to the pipes that extend away from the pipe that you were in.  Now kill
the bullsquid in the toxic pool below and get a running start to get on the
platform below.  Grab any health packs and power cells that you need and follow
the corridor ahead.

Jump onto the pipe and follow it until you get to another pipe that goes
towards the platform in the middle, jump onto it and kill the bullsquid below.
Jump on the elevator and proceed upwards by pressing the button.

Get off the elevator and look right, shoot the bullsquid in the ass and get
onto the walkway.  Oh, look, the houndeyes want to play!  You know what to do.
Dispatch them and proceed ahead.  Of you shoot the containers by the green
houndeye you will blow out part of the bridge and you will have to jump over a
large gap.  So unless you want to do the previously mentioned shoot the
houndeye itself and then take out the headcrabs.  Grab the health packs to the
right if you need to.  Enter the silo door and turn the lever.

Immediately a mawman will come at you and you\'ll have to shoot him.  Do so and
proceed forward.  Hey, what\'s that noise?  Walk forward and you will see a
scientist running around, he will be attacked by a big, worm-like creature
with a beak.  Anyway, you will see a button that says \"Test Fire\".  It is
broken so guess what you get to do, that\'s right you get to fix it.  Now push
the button if you want but it won\'t work, just like I said, proceed down the
corridor and look up.  Shoot the barnacle and climb up the ladder.  You will
see a Barney.  He\'ll say, \"Be quiet, it can hear you.\"  Now turn the corner and
watch the other Barney get smashed by the giant tentacle.  Now, get out your
grenades and you will need to throw a few here.  crouch and walk all the way
through this part.

Throw a grenade towards the boxes by the ladder once you are down to the next
level.  The boxes should explode and the tentacles will come and bash the area.
Now look to the next level see the opening with the boards over it?  Throw a
grenade there to open it up.  Now get on the ladder and climb down a level.
Look down to the bottom level and throw a grenade towards the last boarded
entrance.  Now go in through the entrance on this level.

Open the silo entrance and shoot the mawman on the bridge.  Follow the corridor
to a ladder.  At the bottom there are two mawmen.  Shoot them from above or use
a precious grenade.  Go down the ladder and smash open the hatch.  Proceed down
the ladder and you should find yourself in a tunnel with water on the floor.
Stay on the pipe and go left at the fork.  Climb up the ladder and shoot the
mawman at the top.  Grab some grenades from the side room and open the door
ahead with the keypad.  Shoot the two mawmen and climb down the ladders.  Press
the button down by the base of the large fan and immediately climb up past the
swinging fan blades.

When the fan reaches full speed, jump out over it, no I\'m not crazy.  The wind
will take you up to the top of the room, smash through the boards and get into
the vent on the side.  Smash the opening and beware of the headcrab.  Proceed
through the vent until you get to a room.  Shoot the mawmen and activate the
fuel and oxygen lines.  Two lights should appear on the control panel.  Climb
up the ladder and go out the door using the keypad.  Now exit the silo and go
back to where the giant tentacles are.  Throw a grenade to distract them and
climb down to the next opening.  When you enter it go to the right and shoot
the mawman.

Open the entrance to the silo.  Shoot the bullsquid and proceed to the hallway.
Now when you get to the large open space move the metal crates on the floor to
the water puddle that you passed and line them all up so that you could walk
over them without touching the water.  You\'ll see why later.

Press the button for the elevator, but do not get on the elevator, use the
ladder to the right, the elevator will fall all the way down the shaft if you
operate it.  Hop up on the railing and jump over to it.  Climb down and proceed
past the scientist to the other big shaft.  Press the button on the platform
and it will move you to the ladder on the other side.  Climb up, beware of the
malfunctioning platform up here, do not get hit by it or you will die.  Climb
up the ladder and press the button on the side of generator.  Ignore the
scientist on top of the platform.  Push the button on the other side and the
generator will activate.  The scientist will yell, \"Oh dear!\"  Well, he\'s
screwed.  Proceed down the ladder and avoid the platform.  Go down to the next
level and activate the platform to bring you back to the area with the
scientist.  Climb up the ladder and get on the platform on top.  Jump to the
top of the elevator and jump back down to the platform.

When you head back you will see that the puddle of water that you saw is now
electrified.  One touch would kill on contact.  Now aren\'t you glad you
followed my advice?  Exit the silo and get back to the area with the giant
tentacles.  Climb upwards to the top while distracting them with grenades.  Now
go back to the room where the scientist was attacked.  Now since you activated
all the systems th engine now works.  Now can you guess what we\'re gonna do?
Have a barbeque!  I hope you like your meat well done!  Well push the button
and watch the tentacles cook.

Now go into the pit that the tentacles were in.  Make sure you land in the
water.  Grab Barney\'s Magnum and swim down through the holes and up the side
of it.  Now, if you need health, or HEV power grab some from the bottom of the
ladder.  Get onto the pipes and follow them to a large gap in the pipes.  Jump
over and spin the wheel.  Get in and follow it until it breaks and you fall
into a room.  You will lose a bunch of health, but there is enough health packs
in the crates to make up for it.  You will also get a few tripmines.  Follow
the corridor down.

0004.6           Power Up
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------

Run past the gargantua and into the hallway on the left, take the left fork and
stop right where the bridge starts. When the bridge collapses, jump to the
bottom and take out the headcrabs.  The ladder leads to a room with an injured
Barney and an HEV station.  Go down the hall and kill whatever beings may lurk
here, use the first aid station if you want to.  You will come to a marine
behind a bunker which is conveniently located next to explosive crates.  You
know what to do here.  Go through the area shooting the marines and you should
eventually come to a set of winding stairs, go all the way down and you will
come to a water filled basement, See the boxes blocking the generator?  Smash
them with the crowbar and the generator should start.  Now go up one level
after killing the mawman.  Push the button on the generator and a green light
will show up.  Now go to the staircase and go up between the power surges.

Now when you go back to the elevator you will see two marines descending.   Use
an MP5 grenade and that should kill them both.  Now head back to the Gargantua,
head into the corridor to the left, make the gargantua follow you, and press
the power switch at the end.  The Gargantua should die a horrible and painful
death.

Get on the tram car and make it go to the switch track.  Now go back to the
control room and pull the lever.  Get back on the tram car and proceed forward.

0004.7        On a Rail
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------

I hate this part.

You will come to a Barney and he will tell you that you have to activate a
rocket and more stuff.  Jump off the tram and pull the lever to raise the gate.
Proceed forward.  You don\'t have to kill the barnacles on the ceiling ahead so
save your ammo.  All I can say now is use your gun to change the direction by
shooting the signs with the arrows.  Kill all the Marines and voltiguants.  Use
the switches to lift up the gates and obstacles.

Eventually you will come to an area that has two marines.  They\'ll start
talking about you.  Use an MP5 grenade right in between them to shit them up.
Now go through the blast doors.  Use MP5 grenades to blast the marines on the
other side of the door.  When you go into the room you will see 3 trip wires.
Push the long metal box to the other one so that you can climb up and go
along the edge of the room, above the tripwires.  When you go through the door,
use an MP5 grenade just around the corner to get two marines.  Now go into
the control center and push the \"Launch\" button.  When the launch stops go back
the way you came and use the first aid station of you need to.  Go through the
blast doors and to the left, go down the ladder and get all the ammo.  Get on
the tram and proceed.

0004.8           Apprehension
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------

Get off the Tram car after the corner and let it keep going.  It will crash
over the water pit.  Kill the marines. Eventually in the water pit some barrels
will float up making a bridge.  Cross it and kill the two mawmen.  Use the
first aid station and go to the other side of the water pit.  Jump in the water
and swim along the corridor, enter the side room for air.  When you come to a
room with bars on the windows go into the other opening in the wall opposite the
door.  You will come to a room with a large pool of water and then you\'ll see a
scientist get eaten by some kind of shark creature.  Go to the ladder and the
scientist will tell you to get the crossbow.  Use the HEV and health stations
and then drop into the shark cage from above.  It will fall eventually and then
you can take safe shots from inside the cage.

When he is dead go into the small tunnel that has to be opened by turning the
wheel, it will take you to a room with a large amount of barnacles.  When you
smash the boxes two voltiguants will spawn and will attack you promptly.  Kill
them with the shotgun and go into the next room, another pool of water, but
this time it has two ichthyosaurs.  Well when they come up to the surface you
can shoot them or if you prefer a  more direct approach you can jump in the
water and see what you can do before they kill you.

Now jump through the hole in the fence.  Swim through the passage and you\'ll
find yourself in a room with 3 vertical structures, climb up the ladder and go
to the control center, activate the machinery and kill the bullsquids while you
are waiting.  Now jump from each platform until you get across the room. Now
proceed forward.  Kill the three voltiguants and the headcrab and the scientist
will open the door.  Remember to recharge your HEV suit.  Enter the freezer.

Run like mad through the freezer because it is frigid, ignore the enemies as
best you can and eventually you should find a ladder go down.  Kill the three
voltiguants and watch for the one behind you.  You will find an elevator.  Go
up.

Uh, oh!  Looks like somebody is here to get you.  Hmmm, what are those
footsteps?  They are from the military assassins.  These are fast little
mothers.  You can either use MP5 grenades when they get close to you or you can
fire at them with the normal fire, but that takes a lot of ammo.  There are
three that you have to kill.  When they are all dead go up to the top platform
and pull the surface access switch.  You\'ll see a first aid station, go to it
and the screen will go black.  Listen to the cut scene.

When you come to, you\'ll find yourself amid some boxes.  Then the walls will
start closing in on you.  It\'s a giant trash compactor!  Well, you\'ll have to
jump up using the boxes and then crouch and go onto the small ledge.  Wait for
the compactor to stop and cross the room via the top of the walls.  Get the
crowbar to the left and go down into the pipe on the floor.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------

Exit the pipe and go to the right.  Two headcrabs will spawn, so eliminate
them and proceed onward.  Turn the wheel on the side of the tower and climb up
the ladder quickly.  Drop down onto the descending platform and crawl into the
pipe when it stops.  Get out and follow the Barney he will get eaten by a
barnacle and he will drop his 9mm handgun pick it up.  Go down the stairs ahead
after shooting the barnacle and use the HEV station, watch the two headcrabs
under the stairs.  Go back to where you first saw Barney.  Climb up the ladder
and jump from chunk to chunk to get into the vent.  Follow the vent until you
get to another area with tanks.  Jump on the moving platforms to get to the
vent on the other side if the room, to the vent, follow the pipe that you are
on and jump to the next pipe at the last possible moment.  Follow it and get
on the conveyor belt in the next room.

Drop into the pool of water and swim under the opening in the wall.  Jump out
and pass this next obstacle and get back in the water.  Follow the passage and
swim down.  Crouch and swim under the obstacle that is spinning up ahead.  Go
to the right to use the first aid station, otherwise continue ahead.  Get out
of the water and grab the Magnum shoot the bullsquid and if you need to use
the first aid station.  Go to the room next tot he smashers and pull the leer
to reverse the direction of the middle belt if you plan on using that one.  Now
this gets a little tricky.  Press the switch in the room with the Barney and
hop on the conveyor belt to bring you past the mashers before you get squashed
when they start up again.

Hop onto the double belt and let it take you to some hazardous machinery.  Make
your way past them and hop onto the single belt that moves towards your right.
Get on the belt that moves to your left and shoot out the tripmine before you
hit it.  This also contains another tripmine, but you have to shoot it out
quite close to yourself, this will take away about 10 life points.  Now , when
you get to the end of this one do not drop straight down, move off to the side.
Drop down onto the conveyor belt in between mashes.  Run and jump onto the
ladder.  Climb up and proceed through the corridor.

Smash the grating and throw a satchel up on top.  Detonate it to kill a bunch
of houndeyes.  When you get out be prepared to kill anything that remains.  Go
into the next room.  When the alien grunt breaks through the glass kill him
with 3 shots with the magnum.  Smash the cover over the button to open the door
  Now you\'ll see a group of headcrabs that are contained within a cage.  Move
to the control center and push the button.  Mwahaha!!  Now kill the marine who
came to investigate the noise.  Take his MP5 and go into the reception area with
Barney following you.

Kill the marines and proceed through the tunnels when you get to a lab with
trip mines shoot them and hide.  Wait for the battle to end and wipe up the
survivors.  Now proceed upwards and kill the marines after the battle is done.
Activate all the power switches to turn on the lasers.  When you turn on the
one by the explosive crates there will be a conversation that goes like this,

Barney-\"What\'s this?\"

Scientist-\"Put that down its still experimental.\"

Barney-\"Whoa!  Why aren\'t we using this?\"

Scientist-\"It\'s much too unpredictable.  Don\'t let it overcharge!!\"

Both-\"Aaaarrh!!\"

Get the gauss gun from the room.  When all the lasers have been activated push
the crate in the room to the edge of the testing platform, by the wall.  Push
the button on the control panel to test the laser.  The laser shield will come
down but the crate will block it and it will go back up.  The laser will blast
right through the wall.  Jump down and go into the room.  Three scientists
will be there.  Stop the operating equipment and get one of the scientists to
follow you back to the reception area so that he can operate the retinal
scanner.  Go out through the revolving door.  Kill the marine to your left and
toss few MP5 grenades on the roof to disable the turrets.  Blow up the
explosive crates and open the door.

-------------------------------------------------------------------------------

Kill the marines in here by utilizing the conveniently placed explosive barrels
and proceed onward. A helicopter will appear, to shoot it down use two fully
charged gauss shots.  Jump into the water and climb up the tower, use the first
aid station and turn off the turbines.  Kill the ichthyosaur and open the
grating with the wheel.  Follow the channel to some pipes get in and follow
them.  Kill the headcrabs to the left and get the health pack.  There is ammo in
the crates by the ladder.  Shoot down the helicopter with two gauss shots.
Jump across the gap to get 4 power cells and a bunch of ammo and a life pack
or two.

Crawl through the small opening in the rock and go right.  Kill the marines and
open the drain hatch.  Go to the opening and go forward.  Kill the headcrab
that comes out of the ground and Uh Oh!  There are mines here!  Throw some MP5
grenades around to set off the mines.  Jump into the hatch and go down.  Crawl
through the pipe and you should see a jet go by.

Stand just outside of the surface of the pipe and snipe out the marine below
and the turret.  Make your way down carefully and shoot the marines as you go.
You will come to a large door where you will pick up the rocket launcher.  Now
you can either shoot down the helicopter with the rockets or the gauss gun.

Now make your way up the canyon wall and let the headcrab in the pipe jump up
into nothing.  Crawl in the pipe and go right at the intersection.  Go into
the water and go left into the pipe, go right and climb up, you should end
up at the back end of a tank. Kill the marines as they come towards you and
then you can take care of the tank, either with satchels thrown underneath it
or about 4 rockets.  Now if you need ammo go around and collect all of it from
the surrounding area.  Use the two health stations and open the door with the
button by the guard station.

******************************************************************************
I recieved this e-mail on October 18, 2003 asking about a problem that
happened to me in the exact same place.  So I assume that it is a glitch.  The
solution to this turned out to be to reload a saved game from earlier and play
through until he passed that part of the game.


Anyhow...to get to my point..I\'m having something strange happen to me when I
play this game. I get stuck at a certain point. My character will not move...I\\
can swing the crowbar, shoot guns, etc...but he just will not move. I do not
know if it\'s part of the game or what??

The point in your walkthru I am in is section 4.11

\"Surface Tension\" - I\'m in the tunnel at the top of the mountain. I killed
that headcrab, and turn right at the intersection. (you can ONLY turn right,
as there is no other way thru the tunnel) and then I get to the red light
section of the tunnel and the game loads the next part...after it loads the
next part..this is where my character gets stuck. I can sometimes hear the
marines say stuff...but like i said..I dont know if this is part of the game
or what??

Can you please help?

******************************************************************************

Now here is tank number two.  Sneak up on it and stay crouched right near it.
Throw satchels underneath it and detonate them.  Now fire rockets at it.
Once it is down go through the hole in the fence.  Kill the marines and get
the health packs and ammo.  Go through the door by the tank and go forward.

An alien grunt will drop down so kill him and go to the right.  Throw grenades
towards the tripmines and detonate them, look up at the end and toss an MP5
grenade towards the netting to kill a would be attacker.  Now go forward and
toss a few MP5 grenades or normal grenades to detonate the mines.  Before you
have to crouch to go under the wire throw another MP5 grenade towards the
netting above to kill another attacker.

Crouch and go under the wire and throw a grenade towards the explosive barrels
to the left.  That will blow up the circuit breakers that are sending
electricity through the support towers.  Now climb up the tower and get on the
roof.  Drop down through the hole and listen to the scientist.  Well, look out
the door, hmm...tripmines, so what?  Well It turns out that this building
houses 2 nuclear warheads and one exploding tripmine will set off all of them
and would lead to the detonation of the nukes.  Now why would someone do this?
It\'s beyond me.  But, they did it so you\'ll have to deal with it.

There are three headcrabs in this area so shoot them before they set off a
tripmine.  Crouch and go past the smoking security guard.  smash the box on the
elevator below the tripmine.  Now go up the stairs to the control center.
Shoot the headcrab and pull up the elevator.  Now, see why I told you to smash
the box?  Jump from the elevator to the elevator below.  Push the button to
send it down.  Get the hive hand and eliminate the guards that are chasing
after Barney.  In the truck is a turret so beware.  Now proceed forward and
you will hear an explosion.

Slowly crawl up the ramp and look to the right.  Fire charged up shots at the
tank until it explodes, shoot the marines and break open the boxes.  When you
go into the alleyway take car of the gunner above you, behind the netting.  Kill
the marines inside the building and get Barney to open the door to the locked
room.  (starts drooling)  Now stock up on your ammo.  Fill up all your weapons
because this will be a very rare occurrence during the game.  Jump out the
window by the stairs.  Get onto the ledge and follow it inside the alley.  Jump
to the top of the circuit panel and climb up the ladder.

Shoot the marines below and jump over to the other side of the room via the
small ledges.  Wait for the helicopter to appear and eventually two marines
will battle with some alien grunts.  Let the marines kill the grunts and then
go into the shed that they came out of.  Man the rocket launcher atop and blast
through the other shed wall.  Proceed through the new doorway.

Man the machine gun and fire bullets at the slaves until they quit spawning.
Use the jump pad to get to the upper level.  Wait for the battle between the
aliens and the marines to end and then kill the survivors.  Enter the vent and
shoot the creatures as they come down the vent.  Continue on until you see
bullets flying through the vent.  Kill the marines below and open the door but
run away quickly as it will blow up.  This should open up an entrance for you.
Press the button to bring down the car elevator and press it again and get on,
it will go up.  Kill the marines and man the missile lancer, blast open the
door and kill the grunts as they come out.

Go down the passage that they came out of.  Wait for the battle to end and
kill the two grunts that remain.  The room below you has ammo and some power
cells.  Kill the vortiguant and use the health station here.  Go forward and
you will see a marine get tossed through a wall.  Kill the grunt and now fire
a grenade at the marines below to kill them.  Snipe out the marine on top of
the building with the crossbow and if there is a grunt left kill it.  Use the
jump pad to get to the top of the building and jump through the hole into the
water.

Jump into the pipe and go about halfway down.  A marine will throw a satchel in
the pipe.  Get the hell out of there!  duck under the water and wait for the
flames to stop.  Get back into the pipe and kill the marine to the right.
Ignore the battle below and jump to the pipe by the red wheel.  Turn the wheel
and the hatch will swing open knocking you to the floor with the headcrabs if
you don\'t move out of the way.  Get into the pipe and kill the marine at the
bottom of the stairs.  Go up the stairs and get Barney to follow you, have him
open the door and go outside.  Kill the vortiguant in the small alley to the
right and the one at the bottom of the ramp.  Now get Barney to open the
security door past the jump pad.

Enter and have Barney attack the Gargantua while you run away.  Hehe!  Now run
down the corridor and grab the health packs if you need to.  Use the jump pad
to get into the water on the other side if the wall.  Climb up onto the
platform to hear a message.  Now use the targeting map to call in strikes on
targets.  Bomb the comm tower to have it fall towards the left.  Now bomb the
area behind the walls to the left break open the walls and the entrance with
the bombs.  Go down the corridor and up the stairs.

Avoid the rock falling from the ceiling by first going to the right and waiting
until it is all down and then jumping atop the fallen rock to go in the
entrance.  Run to the far side of the room and get the grunt to follow you.
Get back into the room where you heard the radio transmission and activate the
sentry gun with the lever.  Now go back and kill the vortiguant and smash the
boxes.  Proceed down the hallway, ignoring the spawning enemies behind you.
Kill the voltiguants and open the hatch in the floor and let the creatures fall
in.

Climb down.  Go into the second canal and push the box into the canal. Use the
box to climb over the fence.  Shoot the two barnacles and proceed.  Go right
at the fork, and get onto the floor and kill the headcrab.  Go into the water
and past the small waterfall.  Go past the obstacles and shoot the turret
before it sees you.  Kill the marine ducking in the corner.  Gather as many
rockets here as you can.  Climb up the ladder and shoot three marines, staying
out of sight of the tank.  Then quickly use your rocket launcher to jump out
and take a shot at the tank and jump back behind cover.  Once it is destroyed
go into the room with the first aid kit, watch out for the sentry gun on the
left.  Get on the elevator and push the button.

When you come out you will be in a radioactive area.  Try not to walk in any
green spots or you will lose health.  Cautiously go around to the stairs and
kill the marines before they can fire at you.  Go up and out to the balcony
and back in again.  Wait for the battle to end and kill the surviving beings.
Fire the tank to blast through the door and get out your gauss gun and fire
away because it kills fast.  When the grunts and voltiguants are dead slowly
creep out and look to the right use your Magnum to kill the grunt.  Now look
left and use a charged up gauss shot to destroy the cannon.  Kill the grunts
either with the magnum or gauss and go forward.  Open the two doors.

Press the button on the control panel and get on the cargo lift.  Kill the
headcrabs and the bullsquid and smash the boxes for some ammo.  Use the first
aid station after you are sure that there are no headcrabs floating around.
get the grenades and go down the ladder you will come out in a warehouse.  Uh
oh, this looks familiar, looks like there are more of those damn assassins
again.  Well you know what to do, make sure that you get the ones on the
catwalks and the in the stairwells as well.  Use the first aid and HEV, I\'m
sure you\'ll need them, stations and get on the elevator in the shadows by the
catwalks.

Kill the four grunts and the scientist will open the door.  Listen to his
little speech and then let him open the door using the retinal scanner.  Now
charge up with the HEV and health stations and go to the right, get the Egon
gun.  I suggest that you conserve your ammo, so don\'t bother shooting the
headcrabs.  Get on the elevator.  Go down the ramps and you will need to
activate two pumps.

Pump one- When you go down the first corridor a vortiguant will spawn right
behind you.  Get out your Egon gun and disintegrate the grunts inside the
room, there is one on the catwalk, climb up the ladder and go through the door.
Three voltiguants will spawn inside this room so watch for them.  Pill the
switch and exit.  Jump into the water to save some time and go down the
corridor you came.

Pump two- Go down and the ceiling will partially cave in, crawl through the gap
left and enter the door.  Kill the grunts and climb up the ladder, another
grunt will spawn but he will fall right through the walkway.  Jump over the
gap and shoot the barnacles if you wish.  Enter the door and shut off the
steam with the wheel.  Go forward and enter the room.  Kill the headcrabs and
the barnacles , pull the lever on the machine below and the pump will start.
Climb up the ladder and go back, kill the grunt with the magnum.  Jump into
the water and climb out to save some time.  Go out through the passage you
came.

Go to the maintenance station to stock up on ammo and use the HEV and health
station.  Go to the rector core on the other end of the hallway and use your
Egon gun and the magnum to take out the grunts.  Jump into the pool and swim
along the tunnels.  Grab a breath of air here and turn the wheel on either
side.  Wait until the level stops rising and then turn the other wheel.  Climb
up the ladder and shoot the vortiguant.  Climb up the next ladder, avoiding
the electrical beams coming out of the generator.  Shoot the other vortiguant
and enter the door.

Use the ladder in the elevator shaft ad jump to the opening on the next floor.
Get Barney to follow you and use the first aid station if you need to.  Turn
on the steam with the wheel and go forward.  A vortiguant will spawn and a
grunt will come they will both be weakened by the steam a lot, this will make
your job easier.  Now go past the steam after turning it off and kill the last
two grunts with a few shots from the magnum, enter the portal room.

Now you will have to use the portals to get all the way up to the top.  Get
into the portals when the receiving portal is on top of the next platform
above you.  Some portals lead to other places that can get you ammo or health
or other things.

Portal 1- a shitload of headcrabs coming at you.

Portal 2- Go up to next level

Portal 3- ammo, health, power cells

Portal 4- go up to next level

Portal 5- power cells, health packs

Portal 6- a long drop into a portal, health loss

Portal 7- your next objective

Portal 8- HEV station and two voltiguants

Portal 9- portal malfunction, death

Go up through the portals and when you enter portal 7 you will be in a room
with revolving platforms and a vertically moving platforms.  You need to push
two buttons to open this portal.  Get on the revolving platform and then onto
the vertical on.  Go past the blockage and then use the revolving platforms to
go and push the button, now do the same on the opposite side if the room, enter
the portal.

Go out the door and climb up the ladder, avoid the headcrab.  Now wait for the
scientist to open the door for you, now stock up on everything.  This is the
last time you will get an appreciable amount of ammunition in the game.  Get
the long jump module and top off your health and HEV suit.  Go into the portal
room.  Now wait for the scientist to open the portal.  Ah crap, some Xen
masters will appear and now you have to shoot them down before they kill you.
When the scientist gives the OK jump into the portal quickly.

0004.14         Xen
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------

Jump from platform to platform, kill the vortiguant when they spawn and jump
down on the moving platforms.  When you make it down to the main structure
avoid the purple things hanging on the ceilings, they aren\'t street lamps.
They are kind of like sentry guns, just thy can\'t be destroyed.  Enter the
cave by breaking the netting with your crowbar.  Smash the netting around the
butterfly like things to release them.  Press the use key on all of the
claw like structures to open them, the butterflies will drop in there and they
will combine to form a portal.  Jump in.

0004.15         Gonarch\'s Lair
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-------------------------------------------------------------------------------

Shoot the sac on the bottom of the huge ass spider creature known as Gonarch.
Occasionally he will spawn out mini headcrabs,  these can be taken care of
with a simple smash with the crowbar.  Just focus your Egon gun on the sac
and fire away, eventually he will run away down a tunnel.  Drop down onto an
outcrop through the netting and get onto the jump pad.  Stay on the jump pad
and fire short bursts at him so that he cannot attack you.  He will run and
jump down into a shaft after this.  Now just fire away from above and he will
fall into a netting and smash a hole in the ground.  Jump in and use the
health pool and enter the portal.

******************************************************************************
I got this e-mail on December 2, 2003.  It complains about a glitch in the
game that happens quite often.  If you find that you have the same problem
the just load up your last save-game and play through again.  That will
usually resolve the problem and if it doesn\'t then er.... you are screwed.


I am on the gonarch\'s lair part of the game.  He ran away from me twice and
is down in a cave thing.  when i go down i fight him but then slide backwards
and down into some pit thing.  He never follows me.  according to
walkthroughs he is supposed to fall down and create a hole in the ground.
After attempting many times and dieing or getting stuck down below with
nothing to kill me, i turned on godmode, noclip and all weapons and proceeded
to unload everyhting on the spiders sack.  No kill, no hole, he just stands
there and leaks out green goop everytime i shoot his thing.  I have no idea
why he wont fall and make the hole.

Now you need to get atop one of those really tall platforms that move
vertically.  Try to stay alive until one of them descends.  When you are atop
one start hopping down to the moving platforms, your goal being the purple
spaceships.  Get atop one and ride to the portal on the floating platform.

Move to a cave and go out the other entrance, use the Egon gun on the
gargantua and then long jump over the gap in the rocks.  Oh look are old
friends from Blast Pit.  Well you know how to get by these things.  Jump up
and use the elevated land to get across.  Kill the two grunts and get into the
portal.

Now kill the enemies quickly in this area or you will die promptly.  So I
won\'t really say much about enemies here.  Get on the moving platform and get
up to the next level.  Get on the upper part of this platform when it descends.
When it rises up get onto the conveyor belt and onto the middle platform.  Use
the other conveyor belt to drop into a pool of muck.  Get out and go across the
double belt.  Now for these voltiguants use the magnum it is a one shot kill,
the masters take two shots but it is the most efficient way to kill.

Get onto the rising platform in the corner and go into the hall.  Throw a
grenade at the container and then take out the grunt.  Kill the grunts,
masters, and voltiguants until you get to the portal.  BTW, the blue things
act as healing pools.

Well get out your magnum our crossbow and snipe out as many voltiguants and
masters as you can.  The get on the platforms and go upwards towards the
portal.  A bunch of masters will attack you once you get near the top, so
conserve ammo.

Now, jump from platform to platform and get into the mean looking portal at
the end.

This is the massive being that the scientist was talking about.  Looks kind of
like a baby, not what you expected, eh?  he has a few attacks, one is he will
fire a barrage of white energy balls at you and they will deal massive damage.
He will also fire a green ball at you which will transport you to some useless
puzzle room which you will have to get out of.  So avoid his attacks by staying
behind the columns.  Also, some common aliens will spawn in this room, you
will have to divert your attention to them and kill them before proceeding.
Also, one more thing, save often during this.

Well, this is pretty simple, see the yellow crystals?  Fire two rockets into
each one.  Or a few gauss shots.  When all three are destroyed, fire at his
head and it will open up.  Then use the jump pad to get inside his head.  Fire
gauss and whatever else you have at the crystal inside his head and he will
die.

******************************************************************************
I recieved this e-mail on Novemner 8, 2003.  It asks about another glitch in
the game.  It can be resolved in the same way as I explained for the Gonarch.
Just load up a previous save-game and play through again.


I was at big baby dude, and I broke the crystals, and  then I blasted him
until green and blue bolts exploded out of him, but he\'s not dead.  I was
using cheats during this.  will he not die?

Well, this is somewhat of an anti-climax.  You may have seen this guy walking
around during the game, in fact I have seen him in about 50 different places
during the game.  So listen to his little proposition and then make your
choice.  If you save right when the door opens you can get both endings.  Both
are somewhat good, I suppose.

0005                              Cheats

-------------------------------------------------------------------------------
===============================================================================

CREATING A CONSOLE SHORTCUT: Before running the game, add the -console
parameter to the call to HL.EXE. To do that, right-click on the shortcut for
Half-Life that you want to edit and choose \"Properties.\" Then, in the \"Target\"
field, leave what\'s there and add a space and \"-console\" (w/o the quote marks),
then click on the Okay button. Now run the game using the shortcut you just
edited. (Note that you can also add -dev to the parameter list to get more
debug-style messages, but it\'s not really useful.)

Or if you\'ve installed Opposing Force also, you should have two Half-Life
shortcuts to run the game with, one of which is called \"Half-Life Console.\"
Run it instead of the regular one if you want to use any of the cheats. Note
that the shortcut on your desktop won\'t be a console shortcut. Either copy and
paste the console shortcut from the Programs menu, or use the instructions in
the prior paragraph to turn a regular Half-Life shortcut into a console
shortcut.

Either way, when the game comes up, you\'ll have a new option at the top of the
main menu called \"Console\" that you can click on. You can also bring down the
console while playing by pressing the ~ (tilde) key.

To get the cheats to work, you need to bring down the console, type
\"sv_cheats 1\" and then \"map c0a0\" (w/o quotes), then use the main menu to start
a new game or load a saved game. Once you do all that, all of the following
codes should work:

* god - god mode toggle
* noclip - no-clip mode toggle
* notarget - invisibility toggle
* impulse 76 - type this code and then load a save; now you can type it again
and again to spawn new marines (note that they attack you unless you have
\"notarget\" in effect)
* impulse 101 - gives an HEV and all weapons
* impulse 203 - deletes the NPC or monster you\'re aiming at

* sv_gravity # - replace # with a number; 800 is regular, and 150 is moon-like
* r_fullbright # - replace # with a 1 to eliminate shadows; a 0 restores to
normal
* thirdperson - switches to third-person view
* firstperson - switches to first-person view
* +cammousemove - mouse moves the camera in third-person mode
* -cammousemove - returns camera control to normal
* chase_active # - chase mode in third-person (1 activates, 0 deactivates)

* give $ - gives the item you replace the $ with from the following list:

   item_healthkit            item_longjump            item_suit
   item_battery              item_antidote
   weapon_357                weapon_9mmhandgun        weapon_9mmAR
   weapon_crossbow           weapon_crowbar           weapon_egon
   weapon_gauss              weapon_handgrenade       weapon_hornetgun
   weapon_rpg                weapon_satchel           weapon_shotgun
   weapon_snark              weapon_tripmine
   ammo_357                  ammo_9mmAR               ammo_mp5clip
   ammo_ARgrenades           ammo_buckshot            ammo_crossbow
   ammo_egonclip             ammo_gaussclip           ammo_rpgclip

The \"map\" command can be used to instantly start a new game in a certain part
of a certain chapter. You start without anything, including the HEV suit, so
you\'ll want to use the \"give\" command or \"impulse 101\" to get that and some
weapons and ammo. Below are the map codes that you can use. Note that not
everything will work properly when you use some of these codes, and you could
easily end up getting stuck (unless you use other cheats like \"noclip\" to
progress).

You can use the \"bind\" command to bind a cheat command to a key. For instance,
to be able to press G to get some Mp5 grenades, type: bind g
\"give ammo_ARgrenades\". (Note that quote marks are necessary there.)

Another way to bind keys to codes is to edit the CONFIG.CFG file that\'s in the
VALVE directory under your Half-Life directory. It\'s a plain text file, so if
you load it up in Microsoft Word, be sure to load it as an MS-DOS format text
file. Find the BIND command section right at the top and modify and/or add
bind statements as desired. For instance, you could add a line that binds the
\"sv_cheats 1\" command to the H key, \"god\" to the G key, \"noclip\" to the N key,
etc.
