Capcom announced that the Xbox 360 exclusive Case West addition to Dead Rising 2 will be releasing in December – word on what day is still lacking.
Teaming Chuck with Dead Rising’s Frank West offers access to Frank’s camera for all your photo taking needs, along with new combo weapons and items. Perhaps more importantly, Capcom mentions that players going through the game solo will take control of Chuck, while Frank will be AI controlled, a mode in which Frank cannot be killed. As for deciding who gets to be Frank in co-op mode, I recommend rock, paper, scissors.
