I decided to do this after getting Half-Life and beating it for the first time. I know that getting Half-Life in late 2002 is a weird thing but, whatever, never mind. Well, I got amazed with this game, it\'s so... hmm... perfect! So here am I writing this, and I hope you enjoy it! If you have something to tell me, contributions, corrections, whatever, e-mail me at [email protected] 2. PLOT ------- You play as Gordon Freeman, employee of the Black Mesa Research Facility. It all starts like a normal workday, in which you\'ll have to do another of those boring experiences. But something goes wrong and aliens teleport to the Black Mesa complex. Now you\'ll have to find a way out and kill any aliens in your way. When you think you\'re about to escape, the marines come. Not to rescue you, but to cover up this case. And they\'ll do it killing everyone that shows up, including Freeman. So, basically, your mission is kill every alien or marine that you see throughout the game. 3. PLAYING HALF-LIFE -------------------- 3.1. Basic Commands ------------------- If you have ever played a first-person shooter, you shouldn\'t have any problems with the commands. Only the jump techniques require a little training. This training can be done at the Hazard Course. But if you have never played a first-person shooter, here\'s a description of the basic commands of Half-Life, using the default keyboard configuration: Arrow keys - Move forward and backward and turn left or right. < and > keys - Strafe left or right. Mouse movement - Used to look at any direction. Mouse left button - Fire weapon in primary mode. Alternative: Enter. Mouse right button - Fire weapon in secondary mode. Space - Jump. Ctrl - Crouch. E - Use/Talk. F - Flashlight. R - Reload weapon. Shift - Walk slowly. 1 to 5 keys - Choose weapons. F5 - Saves a screenshot from the game. F6 - Quick save. F7 - Quick load. Pause Break - Pauses the game. 3.2. Jump Techniques -------------------- The jumps will be a very important part of your adventure, especially in the alien world of Xen. Normal jump - Just press the Space button. Jump in a direction - Press Space and the direction you want to go. If you want to jump left or right, strafe while jumping. Long jump - Run and press Space. Crouch-jump - Jump and press Ctrl. Very long jump - Requires the long jump module. Run, press Ctrl and quickly press Space. It\'s the most difficult of all the jumps. Requires a lot of training. 3.3. General Tips ----------------- - Don\'t waste ammo. Always ask help from the security guards and don\'t kill weak enemies with potent guns. Weapons that should be used wisely: Gluon gun, Tau cannon, magnum, rocket launcher. - Don\'t engage in unnecessary fights. Some enemies don\'t deserve a bullet; you can just ignore them. - Use your intelligence. Example: if two enemies are near an explosive crate, shoot the crate, not the enemies. - If a marines vs. aliens fight is happening, wait until only one side survives to enter the fight. - And the most important thing: explore everywhere. You can get good surprises at unexpected places. 4. WEAPONS ---------- Statistical information taken from PC Generation magazine (Brazil). Ammo: currently/stored. Crowbar - First weapon that you\'ll find. Ideal for braking things, such as crates, grates and glasses. When you run out of ammo, the crowbar is always useful! The only enemy that the crowbar suits perfectly is the hagworm. Damage: 10 pts/hit Pistol - It\'s a 9mm semi-automatic. The secondary mode fires faster. Good for the first levels, use to kill headcrabs, mawmen, houndeyes and barnacles. Damage: 8 pts/hit Max ammo: 17/250 (shared with the MP5) Grenades - Well you know what\'s a grenade! Ideal for groups of enemies and stationary weapons. Damage: 100 pts/grenade Max ammo: 10 Shotgun - Very powerful for the middle levels. Use against vortiguants and bullsquids. Damage: 5 pts/bullet, max 6 bullets primary mode, max 12 bullets secondary mode Max ammo: 8/125 MP5 - This is the main marines\' weapon. It\'s very quick and useful. Use against marines, snarks and grunts. Damage: 5 pts/shot (primary), 100 pts/grenade (secondary) Max ammo: 50/250 bullets (shared with the pistol), 10 grenades Magnum - This pistol is extremely powerful. It can kill many enemies with one or two shots. Use against marines, grunts, Xen masters. Damage: 40 pts/shot Max ammo: 6/36 Tripmine - This mine sticks to walls and shoots a laser beam forward. If the laser gets interrupted, it explodes. You can find them blocking your way too, so be careful and shoot them from a safe distance. Damage: 150 pts/mine Max ammo: 5 Satchel - These explosives can be dropped and detonated when you want. In the secondary mode, you can drop several of them before the detonation. Damage: 150 pts/satchel Max ammo: 5 Crossbow - This bow is a very powerful weapon. The secondary mode is a powerful zoom. This weapon is perfect against enemies who are standing at a long distance. Damage: 50 pts/arrow Max ammo: 5/50 Snarks - These little creatures are very quick and hard to hit. They explode themselves after 15 seconds or so. Be aware that if you\'re near the place you threw a snark, they could attack you instead of the enemies. Damage: 10 pts/attack Max ammo: 15 Tau cannon - This futuristic weapon is from a secret government project. It\'s very powerful on primary mode, but even more on the secondary, that lets you charge it. But don\'t let it overcharge or you\'ll suffer some damage. Use against powerful enemies, like tanks and helicopters. Damage: 20 pts/shot (primary), high damage secondary Max ammo: 100 (shared with the Gluon gun) Rocket launcher - If you need to do high damage, then use this weapon. You can change the rocket path after its launch using the laser from the secondary mode. Use against tanks, helicopters or the alien bosses. Damage: 100 pts/rocket Max ammo: 1/5 Hivehand - This is the same gun that the alien grunt uses. It has unlimited ammo, but you can only fire eight wasps a time. Using the secondary mode, you fire faster, but the wasps won\'t track the enemies like in the primary mode. Use against weak enemies. Damage: 8 pts/wasp Max ammo: 8 (unlimited) Gluon gun - The most powerful weapon in the game. It can make the enemies disintegrate. Damage: 14 pts/uranium point Max ammo: 100 (shared with the Tau canon) 5. ENEMIES ---------- Statistical information taken from PC Generation magazine (Brazil). Health/damage: easy/medium/hard modes. Headcrab - The most common enemy of Half-Life. Quick and very annoying. Kill them with the pistol. Health: 10/10/20 Damage: 5/10/10 Mawman - This zombie is one of the easiest enemies of the game. Kill with the crowbar or the pistol. Health: 50/50/100 Damage: single hit 10/20/20, double hit 25/40/40 Houndeye - This alien dog is quick and likes to hide in the corners. The pistol will do the work. Health: 20/20/30 Damage: 10/15/15 Vortiguant - This alien shoots green energy rays that do big damage, but it\'s easy to kill. Use the pistol, the shotgun or the MP5. If you\'re quick enough, you can use even the crowbar to kill them. Health: 30/30/60 Damage: minor rake 8/10/10, major rake 25/25/25, electrical bolt 10/10/15 Bullsquid - This alien is very dangerous. Its main attack is spitting acid at you. Use the pistol, the shotgun, the MP5 or the magnum. Health: 40/40/120 Damage: bite 15/25/25, whip 25/35/35, spit 10/15/15 Barnacle - This is a weird alien. It sticks to ceilings and drops down its long and sticky tongue. If you touch the tongue, well you can figure it out... You don\'t need to kill them, just stay away, but you can use the pistol to be safe. And if the barnacle is standing on a small height, then you can use the crowbar too. Health: 10/10/10 Damage: death Stationary weapons - There are many kinds of these guns. But all of them should be destroyed quickly. Use the MP5, the magnum, the shotgun or any explosive weapon. Health: varied Damage: varied Marines - These are the government troops sent to kill everyone and cover up the Black Mesa incident. Some of them carry shotguns; some carry MP5s. Use the magnum, the crossbow or the MP5. Health: 50/50/80 Damage: kick 5/10/10, shotgun (each bullet) 3/5/6, MP5 3/4/5 Tentacle - This is the big monster that you first meet in the Blast Pit level. It won\'t see you; just hear you. So if you walk slowly near it you\'re safe. Only fire kills it. Health: conventional weapons don\'t work against it Damage: 300/300/300 Gargantua - This is the big monster that you first meet in the Power Up level. It can be killed by electricity or explosive weapons (grenades, satchels, rockets). Health: 800/800/1000 Damage: slash 10/30/30, fire varied, ground fire 50/100/100 Hagworm - These small creatures do little damage each one, but in-group they can be very annoying. Use your crowbar. Health: 2/2/2 Damage: 2/2/2 Ichthyosaur - This aquatic dinosaur is very dangerous. Use the crossbow to kill it. Health: 200/200/400 Damage: 20/35/50 Assassin - These are the government Black Ops sent to kill everyone who knows about the Black Mesa incident. They\'re very agile and tough to beat. Use the magnum or the crossbow. Health: 30/50/50 Damage: 8/10/10 Alien grunt - These are the equivalent of the marines on the alien side. Shoot its stomach (or any other unprotected part) to do higher damage. Use the magnum, the crossbow or an energy weapon. Health: 60/90/120 Damage: punch 10/20/20, Hivehand 4/5/8 Helicopters - There are two kinds of them: the Apache and the Osprey. The Osprey doesn\'t shoot, but is constantly unloading marines. Use the rocket launcher or the charged up Tau cannon. Health: Apache 150/250/400, Osprey 400/400/400 Damage: Apache rocket 150/150/150, Apache 12mm gun 8/10/10 Tanks - Very dangerous, should be destroyed quickly and with powerful weapons. Use the rocket launcher or the charged up Tau cannon. Health: varied Damage: varied Snarks - These little and annoying creatures are very quick and should be killed with a high fire rate weapon, like the MP5 or the Hivehand. Health: 2/2/2 Damage: bite 10/10/10, explosion 5/5/5 Xen master - This is probably the toughest of the normal aliens. They can fly and shoot energy balls at you. Use your magnum to put them down. Health: 60/80/100 Damage: 15/25/35 Gonarch - A spider looking alien that has lots of health. It can spawn little headcrabs that are difficult to beat because they\'re very fast. Shoot with powerful weapons at its pouch to kill it. Health: 2100/3150/4200 Damage: slash 50/60/70, blast 100/120/160, radius blast 250/250/275 Nihilanth - The final boss. Actually not that hard for a final boss. It shoots energy balls and portals at you and can spawn some vortiguants and Xen masters. The portals send you to areas in which you have to make your way back to the battle arena. Use the rocket launcher to destroy the healing crystals, any weapon to open its head and the Gluon gun to destroy its brain. Health: 800/800/1000 Damage: 30/30/50 6. WALKTHROUGH -------------- You play as Gordon Freeman. At the long and kind of boring intro you\'ll learn more about you and your workplace. When the train stops, a security guard will unlock the door for you. Remember the last phrase the train radio announcer said, \"Have a very safe and productive day\". Haha... Exit the train and wait for the guard to open the big doors. Oh my God... he moves so slowly. 6.1. Anomalous Materials ------------------------ Enter Sector C and go right. Follow the green line on the wall to come to the locker room. Go left, press the button and vest your HEV. Go to your locker and get an energy cell inside. You can also see a pic of Freeman\'s baby here (at least I think it\'s his baby!). In the toilet to the right you\'ll find a medical station. Use it to recover your health (duh!). Go out and now follow the blue line on the wall. Make your way to the test lab. Inside the test lab, go up the ladder and press the button to activate the rotors. Wait to the specimen to come and push it into the big machine. Oh... something\'s going wrong here! The whole system will collapse and you\'ll be teleported to Xen, the alien world. Don\'t worry; you\'ll get back to Earth in a while. 6.2. Unforeseen Consequences ---------------------------- Look at what you\'ve done Freeman! The whole lab\'s chaotic and almost everyone\'s dead. Go back and open the door. Get the medikit near the scientist and WALK through the next corridor to avoid the computer terminal. Go back and up the elevator. Talk to the scientist and go to the door. He\'ll unlock it for you. Don\'t hurry! A laser will start to blow up the computers. After it blows the door, go ahead (don\'t touch the laser). Go through the hallway and you\'ll come to another laser. Crouch under it. Just run under the second laser. Near the door you\'ll get the crowbar. Break the glass and go to the elevator. After the disaster, break the glass and go up the ladder. Help the guard and kill the mawman. After he kills another mawman, ask him to follow you. Now he\'ll kill any enemies that come to your way! Until he dies, of course. Go back to the locker room. Inside the open locker get two pistol clips. Go back to Sector C entrance and a headcrab will appear. Let the guard kill it and then kill the guard to get his pistol. Enter the hole in the wall and watch out the terminals. Go to the left corner and use the terminal to get to the hole. Keep going and get the ammo from the dead guard. Use the medical station if you need it. In the next room kill the two houndeyes and go left. You\'ll see a man looking at you. Ignore him. Kill two more houndeyes and jump through the window to the left to find a medical station. Exit, go right, enter the door and kill the headcrab. Go up the ladder and shoot the explosive barrels to kill the aliens, but watch out the explosion. Continue through the walkway and kill the mawman. Go back to where you shot the explosive barrels and you\'ll find a scientist in a corner. Ask him to follow you and go back to where you killed the mawman. Get inside the small room, get the ammo and use the medical station. Go to the walkway and jump down. Go left and wait, the door in front of you will be break open by a vortiguant. Kill it and get the ammo inside. Exit the room and go right. Kill the headcrab near the dumpster and use the medical station. Go back and you\'ll see a hole in the ground. Kill the headcrab down in it and the mawman through the fence. Now fall down in the hole. Explore the area and turn the wheel when you find it. The water level will rise and you\'ll have to swim. Quick find a hole in the ceiling (not the one you came from, this one has a grate). You\'ll come to a lift. Get the ammo from the dead guard and use the lever. Jump down onto the lift, go to the corner nearest the wall and crouch there. If you did it correctly, you\'re safe. If you did not, a horde of headcrabs will attack you. Don\'t wait the lift to go completely down, jump onto the platform with the medical station instead. Go down and kill the houndeye. Get ammo from the crates (there\'s another medical station to the right, but I really think you don\'t need it). Go through the tunnel and to the bridge. A bullsquid will teleport and break the bridge. Use the pipes to your right to cross. At the end of the pipes, you can jump directly to the left or use the shaft to the right. Anyway, you\'ll come to an HEV battery. Break the small crates to get more batteries. Look down and you\'ll see a bullsquid killing some headcrabs. Wait until it stops and kill the bullsquid. Fall down to the crate so you don\'t lose health. To the right is a medical station. Enter the canal and find a ladder to the left. Climb it up. There\'s another medical station. Go right through the door and kill the remaining headcrabs (if any) and go to the door. Climb the two ladders and use the hanging crates to get to the other side (if you\'re not perfect at jumps yet, save the game before you do it). Follow the path to the elevator. 6.3. Office Complex ------------------- Go up the elevator and get the medikit and the battery. Enter the shaft to the left, but don\'t get too close to the electrical wire. Go left and then right. Break the grate and get the ammo, avoiding the fan. Now go back and through the other grate. Enter the room and find the door with the \"High Voltage\" sign. Shut down the power and go back through the red doors. The door in the back is locked, so use the table to get through the window. Go left to the storage and kill the mawman that\'ll break the door. Get inside and collect the ammo. Go left to find several crates. Break them all and kill the headcrab. Get the shotgun in the next room. Get near the guard and kill the mawman. Get inside, take the health and ammo and kill another headcrab. Go down the ladder and get a medikit and a battery from the crates. Get back to where you killed the first mawman in this area and get to the lab through the window. Kill the headcrab and get to the switch without touching the floor. There\'s a health station and a battery in this room. There\'s also a shaft here. Throw a grenade inside it to kill the headcrabs then enter. Stay crouched to avoid the fan. Move on and you\'ll fall down. Go back and two headcrabs will fall down too. Kill them and use the crates to get to the ladder. Smash the grate and go down. Kill the headcrab and smash one more grate. There\'s a turret in this room. Wait until the turret goes off and run under it. Switch it off and go through the small door to pick up some ammo. Go back to the turret and through the passage the dead scientist came from. Throw a grenade to kill most of the headcrabs. Go up the stairs to find a guard. Order him to follow you and get the ammo from the crate. Continue through the hallway and enter the first left door. Get a medikit and a battery inside. Advance and let the guard kill the vortiguants. Explore the offices to get ammo and health, but move carefully because they\'re all replete of aliens. Then find the \"Maintenance Access\" sign and shoot the ceiling above it. Go up the ladder and deactivate the turret. Get the ammo, go down and exit this area. Get the medikit from the crate and the health from the station. Go up the stairs and kill the headcrabs. Continue and kill the mawman and the two vortiguants. Go through the red door to find another guard and another medical station. Go down the ramp, kill the bullsquid and get the ammo. When you try to exit two vortiguants will teleport. Kill them; go back and to an area to the left. Kill the mawman and the headcrabs and break the wooden blockade. Go right, kill the two mawmen and use the medical station. Use the lever and get into the freezer. Localize a red switch and activate it. There\'s ammo in a room with a bullsquid. Go back to the freezer entrance. Go up the small ladder and enter the shaft. Continue through the shaft until you can jump to the moving platform. Do so and grab the batteries from the boxes. Now get to the shaft on the other side. Go ahead, kill the headcrab and go right. Grab the battery and the ammo and go backwards to exit the shaft. There\'s a battery to the left. Now go up the ladder and inside the shaft. Go left, kill the headcrab and exit. Go up the stairs and kill the mawmen. Get inside the two left rooms for medikits and ammo. Now go to the back of the corridor. Jump to the ladder and go up to the elevator. 6.4. \"We\'ve Got Hostiles\" ------------------------- Go right to find medical and HEV stations. Continue and stop at the lasers. Destroy the chain gun with a grenade then enter the room. Kill the headcrabs and break the crates to pick a battery. Go to the next hallway and jump over the tripmine. Crouch under the next one. Kill the vortiguant and use the medical station. Go back and down the ramp. RUN past the laser and hide behind the crates. Two vortiguants will teleport behind you, kill them. Throw a grenade at the chain guns to eliminate the problem. Break the crates to get some grenades. Go up the metal crates and shoot the switch near the fire door. RUN through the door, if you do it quick enough you won\'t get shot. Go up the crates and you\'ll come to a wet floor area. Move slowly. Throw grenades to destroy the two chain guns. There are a medical station and some items inside the crates in the corridor. Go up the ladders and you\'ll encounter a marine. Use your MP5 to kill the new enemy. Go down, use the station and pick his ammo. Go up the elevator. Kill all the marines in the next big room. After they\'re all dead, break the crates to get ammo and batteries. There\'s also medical and HEV stations here. Go up the stairs and cross the bridge. Go right to find some conveyor belts. Walk through the first one and you\'ll find medical and HEV stations. Go up the crates and get to the next conveyor belt. The next room has a marine. Kill him, get the ammo and use the medical station. Throw a grenade down to destroy the tripmine, then get through the door before it closes. Kill the marines and go up the stairs. At the uppermost level, go right to a medical station. Now go left, cross the bridge and you\'ll find another room with marines. Kill them and get the batteries from the crates. Use the medical station and go up the elevator. Kill the marines and use another medical station. RUN into the outside and go down the ladder in a small bunker. There, use the stations. Enter the vent access; jump down and to the ladder. Go down and enter the shaft. In its end there\'s a big fan. Jump left to enter the first shaft. In the first right opening there\'s shotgun ammo. Go back and to the right again. Kill the headcrab when you turn and then the marines through the grate. Exit the shaft to pick up some ammo. Go back, right and left. This room has a medical station, batteries and ammo. Go back to the fan. Walk on the edge to the right and enter the next shaft down. There\'s shotgun ammo at the end. Go back to the fan and down to the last shaft. At the end go up the ladder and enter the first shaft. In the room with the scientist, press the button. Go through the door that\'ll open and follow the hallway. 6.5. Blast Pit -------------- Destroy the barricade and kill the aliens. Go right, kill the mawman and take the items. Use the lever and go down the lift. Get onto the cart and go forward at the maximum speed. Near the toxic pool, jump off of the cart. Go to the platform to the right and kill the bullsquid. Crouch under the pipes and go up the ladder. Go left and enter the open pipe. In its end jump off and kill the bullsquid. Go right and jump to the lower pipe. Jump to the pipe and then to the right entrance, avoiding the bullsquid, and collect the medikits and the batteries. Go to the next toxic pool and use the pipes to get to the elevator. Go up, shoot the explosive barrels to kill the bullsquid and go right. Kill all the houndeyes and take the medikits. Continue through the bridge and kill the headcrabs. Enter the door and open the next using the switch. Kill the mawman and enter the control room. To kill the huge tentacle, you must activate the oxygen, the fuel and the power. Continue, go up the ladder and the security guard will tell you to be quiet. If you don\'t make sounds, the tentacle won\'t attack you. Go right, take the grenades and enter the tentacle room. REMEMBER: walk; don\'t run! Get down one level and down the ladder. Enter the door with the barricade and enter another door with a switch. Kill the mawman and get the medikits from the crates. Continue to the right and you\'ll find a ladder. Don\'t climb it down, jump over the fence instead. Quickly break the fence and go down the long ladder. Go left at the junction and up the ladder. Kill the mawman and get the grenades to the left. Open the next door, kill the mawmen and go down the two ladders. Activate the switch and go back up. Jump in the fan and the wind will blow you up. Break the wooden barricade and the grate to enter the shaft. Go ahead killing headcrabs and you\'ll come to a room with three mawmen. Kill them and the headcrab, then activate the oxygen and the fuel. Go up the ladder and open the door. Go back to the tentacle and through the door one level down. Jump over the gap, kill the mawman and unlock the door. Kill the bullsquid and the next houndeyes. In the next room, kill the bullsquid and use the metal boxes to create a bridge over the water pool in the last corridor, so that you can pass without touching the water. You\'ll know its usefulness later. Test it to be sure it\'s working. Use the medical station in the room and use the switch to make an elevator come down. Go down it. When it stops, jump to the ladder to your left. Go down, jump to the platform and use the medical station. Go left, jump on the pipe to cross the toxic leakage and kill the mawman. Use the switch to make the platform go up. Go up the ladder and to the walkway. Don\'t let the platform that\'s out of control touch you or you\'ll die. Go up any of the ladders and activate the switch. Jump over the top and activate the other switch. Now you activated the power and must kill the tentacle. Make your way back to the bridge you made with the metal boxes. The reason you can\'t touch the water is that it\'s now electrified. Now make your way back to the control room past the tentacle. Press the test fire button and watch the tentacle burn. Go back to the tentacle room and all down again. Go down to where the tentacle was and fall down into the water. Exit the water and get the magnum and some ammo for it. Jump back into the water and swim down. Enter one of the holes and make your way to the exit. Go down the ladder and use the stations. Go back up and over the pipes. Make your way to a wheel, turn it completely left and enter the pipe. Jump the gap and turn right, left and right. Now, move carefully. A part of the pipe will collapse; so make sure you land on a crate to smooth your fall. Kill the headcrab and take all the items from the crates. Go through the hallway. 6.6. Power Up ------------- Go into the hall and go to the left of the gargantua (you can kill it now using your grenades, but there\'s a safer way). Go right and kill the vortiguants. Go back and through the left way. Avoid the fire jet and kill the two vortiguants. Kill the headcrabs then drop down. Get ammo from the crates then follow the hallway. Kill all the enemies then use the station. Open the door using the wheel and climb the first ladder. Kill the marine on the upper level and go left to get some ammo. Go up the next ladder and left. Destroy the chain gun, kill the marine and use the station. Then, get ammo from the crates. Go through the hallway and shoot the explosive crates near the marine to kill him. Collect the ammo and go down the ramp. Collect the grenades and use the station. Now go up the other ramp. Kill any marines in the next area then go right. Inside the crates you\'ll find ammo and medikits. Go back and to the left, there are a medikit and an HEV station. Now press the switch near the lift, but don\'t go down it. Instead, shoot the tripmines at the bottom. Now you can go down. Kill any houndeye then go left and down the stairs. At the bottom, kill the mawman and break the crates near the machine. Go up to the next level and activate the power generator. Use the medical station and go back up. The lift will come down with two marines on it. Hide and wait a bit. The marines will be killed by... hmm... I don\'t know. Anyway, go up the lift and kill two more marines. Now backtrack to the gargantua. Run to the big left entrance and make the gargantua follow you. You\'ll find a power station. Activate it and the gargantua will be killed. If it didn\'t follow you, use the door to the right to go back to the gargantua and make it follow you. After it\'s dead, go back to the now empty big room. Use the cart and go forward until it stops. Go back to the part where a bridge collapsed and through the barricade. Use the HEV station, collect the ammo and push the lever. Now you can continue riding your cart. 6.7. On A Rail -------------- Your cart stops. Take the medikits, use the switch and continue onto the cart. The first thing you\'ll find is a battery to your right. When you see some crates to your left, stop the cart and get their ammo (remember not to touch the yellow and electrified part). Continue and crouch under the electrified wire. When you see two houndeyes and a bullsquid, stop and kill them. Continue and change the next marker for straight. There\'s a bullsquid on a platform to the right. Kill it and get the medikit. In the water pool ahead of you there\'s magnum ammo. Past the water pool and to the left there are a battery and grenades. A bit ahead there\'s a bullsquid to the right.

Get behind it for cover. There\'s a healing pool on a floating rock accessible from here. Shoot some rockets at the spider\'s pouch and it\'ll eventually run away. If you run out of rockets, use any high damage rate weapon. Follow Gonarch through the tunnel. You\'ll find more items inside it. Shoot more rockets at the spider and it\'ll run away again. Don\'t follow it yet, fall into the small hole in the left corner instead. Kill the many headcrabs and jump to the left. Use the healing pool then get onto the other platform. Get the items and use the alien pad to get back up. Enter the tunnel Gonarch went too to come to the final battle place. Move slowly or you\'ll fall down. Shoot at the spider a little more and it\'ll break the webbing. If you\'re good at your aim, you can kill it now without going down. Anyway, after it\'s killed, get the items and fall down in the hole it has opened. Use the healing pool and jump into the portal. 6.16. Interloper ---------------- Get out the rock you\'re on and RUN to the other side. Enter the cave to the right, kill the vortiguant and get a battery on the healing pool. Enter the hole, destroy the webbing and follow the tunnel. Kill the headcrabs and continue. In the room, kill the bullsquid and get some items. Break the webbings to the left and a pillar will come down. Go up with it and kill any near aliens. Now you should use the platforms and the alien flying things to get to the portal. Take the battery, exit the cave and go right. Enter the small cave on the other side, avoiding the tentacle. Here you\'ll find a healing pool. Follow the other tunnel to a new cave. Scale up the rocks on the left to get some items. Now exit the cave and kill the aliens outside. Enter the other cave, kill the vortiguants and take all the items. There\'s also a healing pool here. Now exit this cave and go back to the last one. Enter the narrow tunnel, jump over the rocks and you\'ll meet another gargantua. Go right and enter a small hole for some items and protection. You can kill the gargantua using your explosive weapons, but you can also avoid it. When the gargantua goes out of the room, get out of the hole and jump over the rocks ahead of you to come to a new area. On the left side there are a battery and some grenades. Go right, kill the alien grunts, take the items and step on the portal. In this area, the vortiguants won\'t attack you, so don\'t attack them. Take the items on the lower level then go up with the lift. Go right and you\'ll find a healing chamber. Get onto the upper part of the lift and then on the treadmill. Jump to the second one and you\'ll fall down to a toxic pool. Try to land on the ground. Now you should kill all the aliens, even the vortiguants. Fall down to the lower level. Here, you\'ll find some items and a healing chamber. Go up the lift and right. Get past the treadmill and into a new area. Kill the aliens and follow the path. Go up the pillar and into the corridor. There are many aliens here, and some hidden items too. When there\'s a barrel blocking your way, shoot a rocket at it, then finish off the alien grunt.

Kill the aliens then go up the ramp. Use the healing chamber and go up the lift. Kill more aliens and enter the room for some items. Go up one more lift, kill more aliens and use the healing chamber. Take the final lift and jump into the portal. Jump from platform to platform to reach the big portal. 6.17. Nihilanth --------------- This is the final boss, but it\'s not very hard. Actually, it\'s pretty easy. Hide behind the big spikes and destroy the three yellow crystals with your rockets. Without the crystals, Nihilanth can\'t heal itself. Now shoot its head until it opens. Step on the biggest alien pad and use the Gluon gun to destroy Nihilanth\'s brain. And that\'s it; you\'ve beaten Half-Life! At the ending, the government agent you saw throughout the game will explain some things to you and will offer you a job on the government. If you don\'t accept the job, you will be teleported back to Xen and face some alien grunts (but you have no weapons, so you\'re dead!). That\'s it! FIN 7.

EASTER EGGS -------------- In this section I\'ll list the Easter eggs from the game. An Easter egg is any kind of funny or curious situation in the game. If you\'ve discovered an Easter egg that\'s not here, e-mail me at [email protected] - Anomalous Materials: When you passed the doors that lead you into the complex and you stand in front of the desk, the security officer will talk to you. Just step around the desk and press the little button near the keyboard of the computer. It\'s a very little button, so it\'s not easy to find but just give it a try it\'s worth it. (Contributed by guitarhippie.) - Anomalous Materials: Same location. The computer in the corner. Go there and press the button. Another scientist will shout at you and shut it off. Little Easter egg but also an Easter egg. (Also by guitarhippie.) - Anomalous Materials: On your way to the locker room to pick up your suit you\'ll pass a couple of scientist sitting and drinking coffee or something. Press the microwave oven several times until whatever\'s on the inside blows up. (Contributed by Per Ekholm) - Anomalous Materials: When you enter Freeman\'s locker, you can see some books and a picture of a baby (I think it\'s a girl, but I\'m not sure). I suppose it\'s a programmer\'s baby, but if you can confirm/correct this, e-mail me please. - Unforeseen Consequences: At the lobby where the security guard told you to go to the test chamber, take your crowbar to the panel by the door you came in (in the beginning) and smash it. The door will half open and on the other side you will see a scared scientist. Walk a little onto the bridge then back off. The scientist will say \"Gordon!!!\", the bridge will collapse and he will jump onto the wire and slip off. (Thanks to Austin Christensen for this one.) 9. FAQ ------ 1 - Q. What about the several Half-Life mods? Are they all expansion packs to the original Half-Life? A. As far as I know, there are only two official single player expansion packs: Opposing Force and Blue Shift. In Opposing Force you play as one of the marines. It\'s very good and I really recommend it. In Blue Shift you play as a security guard. But it has a short time of gameplay, so it\'s not what you could expect from an expansion pack. But it has also a high definition pack for Half-Life, so you might be interested on it. There are several other good mods available, but none of them are official single player releases. 10.
