I got another cheat - There will not be a sound/sign when this cheat is activated...
Blow body parts off -
S, L1, C, D, L1, R1, T, R, L1, X.
I read that 'Blow body parts off' was going to be in the game until sept 11th, after the tragedy they dicided to take this feature out of the game. Just what i read.
Cheat does work so don't come back and say it doesn't.
