Half-Life Cheats

Half-Life cheats

Console Codes:
Load the game using the '-DEV ?TOCONSOLE' (HL.EXE ?DEV ?TOCONSOLE) command line parameters. If the text does not disappear press the tilde key '~'.

During game-play press the tilde key '~' and type 'sv cheats' at the console window to activate cheat mode. For this code to take effect you must either die or reload your game.

All Weapons and Ammo:
Enable Cheat mode. Then press '~' and enter '/impulse 101' at the console window.

How to get all weapons

Press ~ and type in sv_cheats 1 to enable cheats. Then type in impulse 101.

Addition to monster spawn

I made a mistake in my "Monster spawn" submitted cheat. I wrote "gonore" in the monster list but it should be "gonome". Sorry for that.

I also forgot to write this one:
Ichthyosaur

A cool cheat

You gotta try this one!

-sk_plr_(weapon)(skill) x

Replace (weapon) with any weapon like these: (The number is the default power so don't type it in yet)

Rpg 100
Satchel 150
Tripmine 150
Crowbar 10
Buckshot 5 (shotgun ammo)
Gauss 20

Replace (skill) with the current difficulty level you play 1 = easy, 2 = normal, 3 = hard. This one is necessary.

Replace x with a number. The number you type in is the ammount of damage the weapon can cause. If you simply put in -sk_plr_(weapon)(skill) you will se the default power for the wepons.

It will look like this if you change the crowbar while playing on easy:
-sk_plr_crowbar1 10

Note: Try replacing the power of the satchel with 100000000. Now take one out and detonate it. It will kill everyone and everything onscreen, even you unless you use god mode.

Note 2: Here's the coolest thing. Try replacing the power of the crowbar (10) with a negative number like -20. Now ask yourself: What happens if one causes negative damage to a target? Well, it will actually HEAL the target!! Amazing, huh? This way you can change the health of a target from their original energy to more than 10000 if you want to.

Regular cheats

These are the regular cheats found in Half-life:

God = Invincible on/off
Notarget = NPC's can't see you (Invisible on/off)
Impulse 101 = Spawn all weapons, ammo, a hazard suit and a battery
Noclip = No clipping (can fly and phase through walls)
Kill = Suicide

Note: You don't need to use capitals while typing in the cheats.

Monster spawn

Did you know that you can spawn monsters? Now you do!

-give monster_x

Replace x with any of the following:
Scientist
Barney
Gman
Headcrab
Zombie
Alien_slave
Alien_grunt
Bullchicken
Gargantua
Human_grunt
Alien_controller
Houndeye
Snark
Cockroach
Apache
Osprey
Human_assassin
Tentacle
Barnacle
Bigmomma
Babycrab
Nihilanth
The following ones are only for Opposing force:
Op4loader
Alien_voltigore
Baby_voltigore
Shocktrooper
Shockroach
Blkop_apache
Male_assassin
Cleansuit_scientist
Otis
Human_grunt_ally
Human_torch_ally
Human_medic_ally
Recruit
Drillsergeant
Pitworm
Geneworm
Zombie_barney
Zombie_grunt
Gonore

Note 1: The impulse 106 command will help a lot about figuring out what an enemy is called.
Note 2: If you try to spawn a Non Playable Character (NPC) in an area where they do not already excist the game will freeze, like spawning a gargantua in the tram ride in the beginning of the game or if you try to spawn a scientist while fighting nihilanth.
However: There IS a way to get around it. By spawning NPC's at an area where they already excist you can spawn it right in front of a loading checkpoint and walk through it. In 8 out of 10 times, the NPC will be transferred to the next loading area too. This way, I was able to bring a headcrab all the way back to the beginning of the sector C area (where the game starts) even before the huge catastrophe.

Hope you appreciate my work in writing all of this. Bye!

Impulse commands

Here are all impulse commands I know about:

Impulse 76: Use Grunt-o-matic. Type in the command and quickload the game and it will work, If you don't quickload the game will freeze if you type it more than once.
Impulse 100: Turn on or off flashlight.
Impulse 101: Spawn weapons and ammo.
Impulse 102: Spawn Giblets.
Impulse 103: Check NPC status when looking at them with the crosshair for any weapon. The crowbar has a crosshair but it's invisible.
Impulse 104: Check global entities list.
Impulse 105: Turn stepsound on or off. On = Default.
Impulse 106: Check sprite or NPC status.
Impulse 107: Texture information.
Impulse 109: Controll on-screen NPC. (May not work in some versions)
Impulse 195-198: AI nodes (guidelines).
Impulse 201: Spray logo.
Impulse 202: Blood spray.
Impulse 203: Delete NPC's when looking at them.

Extra command:
Instead of bringing up the console screen all the time you can perform a quickbutton for all commands. bind 0 "impulse 101"
Bind 9 god
Bind 8 "sv_gravity 800"
It works with all commands like noclip, notarget, sv_gravity x or impulses.
Note: If the command has a space in it you need to use "quotes" with the word.
Of course you can assign them to any key.

World physiques

Here are some of the cosole commands that can change the physiques in the Half-life world:

-sv_gravity x
Replace x with numbers: 0 = No gravity, 800 = Default, -800 = Reversed gravity.
Note: It's gravity the way you want it

-sv_accelerate x
Replace x with numbers: Changing the numbers higher than 10 won't affect your speed. But try to put in negative numbers like -200 and your speed will certainly be affected but it will also revers your controller so up means down etc.
Note: Revers your controller before using the accelerating code and there will be no reversed controll.

-host_framerate x
Replace x with numbers: 0 = Default, 0.2 - 100 = Faster and faster gameplay, 0.02 and down to 0.001 = True matrix style (ultra slow).
Note: Combine -host framerate 0.002 with -sv_accelerate 20000 and the game will play really slow but you'll be so quick that you're almost invisible. With this speed you can even outrun a crossbow dart.

-sv_friction x
Replace x with numbers: 4 = Default, 1 = Slippery, 0 = To slippery to stop,
-4 = So slippery that you'll go faster and faster.
Note: The name says it all.

-sv_stepsize x
Replace x blah, blah: 18 = Default
Note: the higher the number, the higher you can walk over. Type in 18000 and you can walk straight up any building. Type in 0 and you can't even go up a stair.

Have fun!

Cheat Action
/god invisibility
/impulse 101 gives weapons and stuff.
/give item
eg. /give_9mmhandgun 357

If it says command unknown that means you wrote it wrong and if it does nothing that means you have to right sv_cheats 1 and save it and load it.

Please note: Some items may not be available in some areas.

Also, If you are using NOCLIP mode and shoot at the floor, you might just
end up stuck in walls, between levels, and really lost.

Camera Changes

This is cool! Call up the console by pressing
the ~ button and type any of these. They do all sorts of camera things:

"chase_active 1" - puts the camera on "Tomb Raider Mode"

"thirdperson" - Puts the camera in a "Third Person Mode" where the next
2 codes are useful.

"+cammouseactive" - activates "Camera Looking Around Mode" which can change your view in
"Third Person Mode"

"-cammouseactive" - deactivates "Camera Looking Around Mode"

"chase_active 0" - deactivates "Tomb Raider Mode"

"firstperson" - returns you to "First Person" mode.

impulse 101 -weapons and ammo-type again and again until it reaches full ammo(if you want).
