The second DLC pack for Black Ops 2 released today, containing four new multiplayer maps and a completely new zombie mode experience starring Ray Liotta, Chazz Palminteri, Joe Pantoliano and Michael Madsen. In their zombie adventure, titled "Mob of the Dead" they depict four prohibition-era mobsters trying to escape the inescapable prison island Alcatraz.
Treyarch's studio head had this to say about the release: "Uprising is equal parts creativity and passion, all rolled into four amazing multiplayer maps and an entirely new and ambitious 'mob of the dead' zombie experience. We've packed a ton of gameplay into the multiplayer maps, including game-changing enviromental challenges and opportunities. And with 'mob of the dead', the team has pushed boundaries of the zombies fiction into new territory, anchored by top Hollywood talent."
