Infestation Codes -

Cheat mode:
Start a new game, then type GIVE IT TO ME BABY (case-sensitive) as a name to enable cheat mode. The message "Cheat Activated" will appear to confirm correct code entry. Enter your desired name and start the game. Go into your onboard computer. A cheat menu will now be accessible. Note: When you "Scavenge Level", you will destroy anything you have not researched yet, such as spawners, enemy, buildings, and seismic stablizers.

Hidden weapon:
Successfully complete the game. Any game that you load or start afterwards will have a weapon called "Cranial Implant". This allows you to use anything controlled by a pilot, for example Aliens, Tanks, Quxles, etc. It is used like Guided rockets, and not selectable by the function keys. You can only select it via the "Next/Prev weapon" option.
