Def Jam: Vendetta/Cheats

Cash, cash and more cash
If you want to buy more pictures and max out your stats, play in any mode with the exception near the last level vs D-Mob of Story Mode. The most effective is survival mode with you against the people available to fight that you unlocked through story mode whether you started or not.

Girls for free
Choose the girl whom your going to stay with throughout the story mode. The girl you stick with up to the point in which you get back at D-Mob and the pictures will be unlocked without any trouble.
