The final DLC release for Call of Duty: Black Ops 2 is "Apocalypse." Available on Xbox 360 tomorrow and other platforms later, the add-on includes four new multiplayer maps and a brand new "Origins" zombie mode.

"Origins" will take players into a WWI-themed zombies campaign, starring the four original heroes from the first Zombies map: Tank, Nikolia, Takeo, and Rictofen. The story promises to explore the origins of the zombie "saga," while giving players access to new supernatural Wonder Weapons, a Mark IV tank, and more--as players try to avoid getting stomped by giant mechs.
