I really need an answer as soon as possible.
HURRY!!

how do you enter the cheats for this game on the ps2? i cant seem to find any button that allows you to do this

What will I do now, I've found Billy the secret man but I can't use him.
If I kill him with my AK2000 (by the way I found that at the start of the game cause my game is for PS2/PC. For some reason it's both) because Billy's walking around with me.

Is there any button cheats, like R2, L2, R1, L1 or something like that?
