During the reveal of the new Uprising map pack for Call of Duty: Black Ops II, Treyarch revealed a new zombie mode called Mob of the Dead. The new scenario takes place in Alcatraz as zombies take over the infamous prison.

Interestingly enough, Treyarch will be attempting to make its zombie mode more of a psychological horror game this time around, instead of the tower defense/survival gameplay of past zombie modes.

Mob of the Dead will be available on Xbox Live first as part of the Uprising map pack on April 16.
