Xbox exclusivity on the latest Call of Duty: Black Ops 2 DLC has ended, meaning PC and PS3 players can now nab the "Revolution" pack. For $14.99, "Revolution" collects four multiplayer maps, a new Zombies locale – with a mode in which you play as the undead – and the Peacekeeper sub-machine gun.
The map pack is also included in the Black Ops 2 season pass, which promises four DLC map packs throughout 2013, in addition to Nuketown Zombies, the first DLC released for Black Ops 2 so far.
