Here are all the cheats for AvP.
AvP Gameplay Cheats
These cheats can be used in the AvP Cheat version of the game. You can only play on levels that you've already completed, and you cannot open up any new levels playing in the Cheat mode. To use them, bring down the console (with the ~ key), and type in the code you want to use. Make sure they are in all capitals.
Also note that sometimes creating bots can cause the game to crash.
OBSERVER - Makes you invisible to all enemies except facehuggers and the Queen. You can still attack to some extent; Aliens can headbite, Marines and Predators can use their active weapon. Good for exploring levels.
GOD - Makes you immortal. Your health will go to zero, but you won't die. Also, if a facehugger gets you, it'll just stick to your field of vision for a while, then disappear. This is good for exploring levels.
GIVEALLWEAPONS - This gives you all the weapons available in the game for your species.
GIMME_CHARGE - This can only be used by the Predator. It restores your field charge completely.
SHOWFPS - Shows the current frame-rate per second on the screen.

Objective Cheats
These can be earned by playing either Realistic or Director's Cut modes and completing certain objectives. The cheats will then be made available in the main menu in both AvP and AvP Cheat modes. Click the available links to see an example of the cheat (if I've unlocked it, that is)!
Alien Episode I - Temple
Cheat: Sniper Munch
Objective: Ten live civilian head bites
This cheat lets you head bite people from very far away. It's fairly easy to get... just watch out that the civilians with the Molotov cocktails don't kill themselves.
Alien Episode II - Escape
Cheat: Nausea
Objective: Complete level in under two minutes
This cheat causes the entire screen to kind of wave around. It's aptly named; you'll get motion sickness trying to play the level with this one! To get it, you just have to know the level and run!
Alien Episode III - Ferarco
Cheat: Pipecleaner
Objective: Fifteen dead civilian head bites
This makes all your enemies have pipe cleaners wrapped around them! What fun! This one is fairly easy to get; just make sure you use your tail to kill the civilians, or you risk knocking their heads off.
Alien Episode IV - Gateway
Cheat: Motion Blur
Objective: Complete the level in under four minutes with an average speed of more than nine meters-per-second
This cheat makes everything that moves kinda blurry and see-through. Learn the level and run!
Alien Episode V - Earthbound
Cheat: Mirror
Objective: One live Predator head bite
This mirrors the level. It's easy to get. A fully charged tail strike will drop him to his knees, then head bite him before he self-destructs.
Alien Bonus II - Derelict
Cheat: Impossible Mission
Objective: Twenty live Marine head bites
This cheat means that you'll take more damage. This is a hard one to get... just try to sneak up on all the Marines or you'll get torn apart. It helps if you destroy the lights. Also, because the Marines respawn, you can keep searching around and/or wait for them to come to you. Just remember to save every five or so headbites.
Marine Episode I - Derelict
Cheat: John Woo Mode
Objective: Eighty per cent head shots
This cheat makes the level move slowly. The best way to get it is to kill one or two Aliens with head shots, then run away the rest of the time. It's not hard because there's only a few Aliens in this level anyway.
Marine Episode II - Colony
Cheat: Grenade
Objective: Forty per cent accuracy
This cheat gives you ninety-nine grenades in your Pulse Rifle, no bullets, and you can’t pick up any other weapons. Using your Smartgun will really help you get this one. You might have to wait until the Aliens are right near you to assure you don’t miss them. Or, you could shoot a few Aliens and try to avoid the rest.
Marine Episode III - Invasion
Cheat: Warp Speed
Objective: Finish in under four minutes
This cheat will speed up things (as opposed to the John Woo Mode cheat). To get this you need to know the level, and have a little bit of luck on your side. If you avoid as many Aliens as you can, you can reach the hangar in three minutes, and it takes about 20 seconds for the ship to come.
Marine Episode IV - Orbital
Cheat: Land of the Giants
Objective: Less than twenty shots
Makes you small, but you're as strong as you were before. Use the Pulse Rifle's grenades and the SADAR if you have to fight, but otherwise just try to avoid battle.
Marine Episode V - Tyrargo
Cheat: Slug Trail
Objective: Thirty-two Alien kills
This cheat makes all Aliens start off with a missing leg, so they all crawl around and leave little trails. This one isn’t too hard to get, considering the amount of Aliens that’ll be attacking you!
Marine Bonus I - Temple
Cheat: Free Fall
Objective: Complete the level with under 100% damage
This cheat changes gravity every so often, so you'll be falling all over the place. To get it, don't pick up any Medikits, only Armour. Using your Flamethrower is also a good idea.
Marine Bonus II - Vaults
Cheat: Under Water
Objective: Complete the level with under sixty per cent damage
This cheat makes it like you're underwater. Things are a little wavy, there’s a bluish tint, and you fall slower. Just don't pick up any Medikits if you want to get this cheat. There aren't too many Aliens in this level anyway, but I don't advise running from them. Take your time and methodically kill them all so you'll be safe.
Predator Episode I - Waterfall
Cheat: Pigsticking
Objective: Eighty per cent accuracy
This cheat makes your Speargun have infinite ammo and shoots a bunch of spears at a time, in a shotgun spread. Just use your Shoulder Cannon all the time to get it.
Predator Episode II - Area 52
Cheat: Super Gore
Objective: Get twenty-five Marine trophies
This makes your kills bloodier. Just don't use your shoulder cannon to kill Marines because it blows them apart. Once you run out of spears, use your Wristblades to kill the rest of the Marines you need for the trophies.
Predator Episode III - Vaults
Cheat: Disco Inferno
Objective: Complete the level with under 100% damage
This cheat makes all the walls glow with bright rainbow colours. Don't use your Medicomp to get it. Use the Pistol a lot and keep your distance, or just run away from the enemies.
Predator Episode IV - Fury 161
Cheat: Balls of Fire
Objective: Forty Alien kills
This cheat transforms all your enemies into flames. Explore the level and kill all the Aliens you can to get it.
Predator Episode V - Caverns
Cheat: Rainbow Blood
Objective: Be spotted less than fifteen times
This cheat makes blood, lights, smoke, and similar things all rainbow coloured and flashing. Your best plan of action is to cloak and run through the level as fast as possible. You can also try to just sniper Marines with your Speargun.
Predator Bonus I - Invasion
Cheat: Ticker Tape
Objective: Get fifteen Alien trophies
This makes all Aliens leave a trail behind them. This is the hardest cheat to get, as there are only seventeen Aliens in the level, Aliens tend to blow up when you kill them, and their corpses fade away really quickly. Hit them near the feet with your Pistol so they don’t explode, then quickly get its head with your Wristblades. Save every couple of trophies you get, also.
Predator Bonus II - Escape
Cheat: TripTastic
Objective: Get ten civilian trophies
This cheat makes everything all wavy and rainbow coloured, like an LSD trip. Kill the civilians with your Pistol to avoid knocking their heads off, or shoot them in the feet with your Speargun.
