Hint: We've Got Hostiles Quickly

Updated 25 Sep
Hint: Completing We've Got Hostiles Quickly

As soon as you enter the "We've Got Hostiles" level, turn to your right and use the noclip code to float through the glass window with the security guard being eaten by the zombie. When you are in there, press the switch that opens the Silo and the Silo door will open. Float back out of the room, disable the noclip code, then go through the Silo door to start the next level.

The following commands are available in console:

/GOD - god mode.
/NOCLIP - walk through walls/fly.
/MAP xxxx - go to map xxxx. Map names are of the format c#a#,

Do not use the cheat codes unless you have been stuck
somewhere for longer than many days. They WILL spoil
the game.

Glitch: Invincible Scientist

Updated 25 Sep
The beginning of the game also has the following glitch. There is a scientist sitting in front of a damaged instrument panel, in the area of the first scientist who opened a door for you. This scientist is invincible. You can shoot or beat him with a crowbar, and all he will do is whine. This also saturates the area with a large amount of blood.

Glitch: Cheats On First Level

Updated 24 Sep
If the all weapons and ammo cheat code is used in the first level of the game, on the train, an error message stating that the hev suit fell out of level will appear. The game will automatically quit.

Hint: Starting Tips

Updated 24 Sep
After the "accident", you will discover a scientist giving CPR to a security guard. Wait 15 to 20 seconds to see the outcome, which usually results in the security guard being revived. He is not useful at this time, but return to him after getting the crowbar. Kill him with the crowbar so he can not fire back to get his gun and ammunition.

Soon after this, you will ride an elevator upward. Have the gun ready. Shoot the monster attacking the security guard; a couple of shots should do it. This security guard can cover you until you reach the main entrance area.

One important tactic in the early game is to use your "allies" to your advantage. When you no longer require the services of a security guard, kill him and take his ammunition. A scientist is also useful in drawing enemy attack. Be careful not to harm an ally when another security guard is present, as he will attack you. Also be aware that monsters can sense your allies; and even if you crawl, monsters can hear your allies' walk.

Spaw A Grunt

Updated 13 Aug
Type "Impulse 76" into the console, it has to be done once, then reload the map, and then you can make grunts.

Impulse Cheat

Updated 24 Jan
impulse 101 - god, noclip, sodacan, suit, tripmine.
