Dead Rising 2: Case West is slated to arrive "next month." As of this writing, it's just barely still November, so it would seem Frank West will return to Dead Rising in time for Christmas. In-game photography will also be making a comeback; presumably, nabbing erotic photos should be much easier this time around.
Unfortunately, Capcom still hasn't announced a price. For now, you'll just have to settle for the new screens in the gallery below.
Update 2: Following up with Capcom, a representative informed Joystiq: "Case West will be a standalone just like Case Zero."
Update: Find a Case West trailer after the break.
