It's your standard movie tie-in game. In other words it sucks. The story I can't remember precisely but it seems to carry on from where the movie Wanted ended. 'twas lame though, the action is fun for a while but just gets sooo boring.
IMHO: Don't get this game. There are so many better games you could.
Left 4 Dead 2, Dragon Age: Origins, Borderlands just to name a few.
