DEADRISING 2
Case West
From Wikia: Dead Rising 2: Case West is an upcoming Xbox 360-exclusive DLC game that takes place after the events of Dead Rising 2, which was announced at the Tokyo Game Show by Keiji Inafune. This game will feature Chuck Greene and Frank West working side-by-side in a factory like setting.
As taken from Capcom-Europe's announcement: "In co-op mode, Xbox LIVE Gold members will see the two protagonists delve deeper into the reasons behind the Fortune City outbreak and provide further links to the Willamette incident."
"The Xbox Live exclusive will provide an epilogue for "Dead Rising 2." As far as whether or not that means the game's DLC train will end there, we'll have to wait and see. Capcom could always squeeze another character or a "further adventures of Chuck and Frank"-style pack into the marketplace."
