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.
Set immediately after the events of Dead Rising 2 and available exclusively on Xbox LIVE, Dead Rising 2: CASE WEST sees Frank team up with Chuck Greene for some serious co-op action as the pair embarks on a brand new case set in the Phenotrans Facility on the outskirts of Fortune City.
Here Chuck and Frank will face new challenges and new enemies but will also have access to new weapons, items and the ability to create a number of new Combo weapons such as the janitor's favourite, the 'Zap & Shine' and the ominous sounding 'Reaper'. Just as in the full game, players will have the opportunity to rescue human survivors who have so far escaped the clutches of the zombie horde.
Wherever he finds himself Frank is always ready to capture the moment with his trusty camera and Dead Rising 2: CASE WEST is no exception. Frank AND Chuck are now able to take photographs of key evidence that will provide indisputable proof of Phenotrans' part in the zombie outbreaks, not just in Fortune City, but across the United States. As the story unfolds expect to see cameo appearances from other characters from Dead Rising that will provide further links to the original game.
Scheduled for release next month, Dead Rising 2: CASE WEST continues the Dead Rising 2 experience and sees the return of Frank West as he partners up with Chuck Greene to find the truth behind the Fortune City outbreak.
Available exclusively on Xbox LIVE, Dead Rising 2: CASE WEST delivers brand new and unique content as Chuck and Frank enter the sinister Phenotrans facility to uncover the pharmaceutical company's involvement in the Fortune City outbreak.
