Cheat mode:

In order to enable these codes you must download the patch. Enter -debug as

a command line parameter to enable cheat mode.

Here’s an easy way of doing this:

You will see something like: c:********exe. Just add -debug to the end of

this command line and then click Apply. Now start the game.

Press ` then enter one of the following case-sensitive codes to activate the

corresponding cheat function.

Hints

Pigsticker:

Finish Level I on Medium Difficutly with 80% or more accuracy, and get the “Pigstick”

Cheat. The “Pigstick” cheat releases about 10 spears from the speargun. EXTREMELY

effective at close range.

Get the Sipemunch:

Getting 10 civilian live head-bites in alien level 1 will get you snipermunch!

You can head-bite from long distences.

Nasty!:

Finish Level II on Medium Difficulty gathering, 25 or more trophies, and get

the “SuperGore” Cheat. The “SuperGore” cheat is self-explanitory. It increases

gore by about 3 or 4 times.

Infinite Grenades in Co-Op Mode:

Start a Co-Op game on a level of your choice. Choose Marine-Grenade as your

class. You have three classes of grenades: Normal, Frag, and Proximity Mine.

Shoot off all rounds of your two least favorite types. After all of two types

of grenades have been fired off, fire off all of your favorite type of grenade.

After you are completely out of grenade ammo, press the button you have set

as secondary fire. You should now have a just about infinite amount of your

favorite type of grenades.
