Black Ops 2: Uprising has arrived on the XBL Marketplace. Time to head to Alcatraz and get your zombie shooting fix with Mob of the Dead. Those not into the whole shooting of the undead, can also play on the Magma, Encore, Vertigo, and Studio maps. Season Pass holders need not drop a thing, while others will need put down 1200 Microsoft Points. PC and PS3 users will get to participate in the shooting frenzy once the exclusivity period with Microsoft ends. Check availability for your area through here.
