There are several sites that have them, but they are all fake and for the ones for Evolution and Predator. Are there any real ones? I just want unlimited ammo because I like this game, but has the terrible burden of ammo famine.

ill hook u up ammo/UnleashHell evolution/FerralAttack infinite adreline/BloodLust heal /ImJackCarver

any clue about the access cards

has anyone figured out the cheat codes yet? Those dont work...

Why do people keep offering the fake codes?
It has already been established that:
"Bloodlust"
"UnleashHell"
"ImJackCarver"
"FeralAttack"

are all 100% malicious fakes which actually have the power to damage both the game and the Wii unit itself.

Only "GiveMeTheMaps" has been confirmed as a real code, though its value is uncertain as it cannot be un-enabled except by profile deletion.
