I found out recently that I won a contest for Crackdown 2 (Xbox360 game). The contest wanted some graffiti art to be placed around their city. So I sent them 3 drawings. The reply said I won, though i'm not sure if all three of them will appear in the game or just one. My name will also be in the credits. Here's the link to the artwork [link]
There isnt a set date release for Crackdown 2 yet, only a "before July" statement.
