This week Activision and Treyarch released a bit of information on the upcoming downloadable content (DLC) for Call of Duty: Black Ops II.

“With Black Ops II, the team set out to challenge assumptions about what fans should expect from Call of Duty, and there’s no exception with Revolution,” said Mark Lamia, Treyarch studio head.

Titled “Revolution,” the add-on will include four new multiplayer maps, “Downhill,” “Hydro,” “Mirage,” and “Grind.” A new map for zombies mode called “Die Rise” will also be included. It pits players against the zombies inside of collapsed skyscrapers in a ruined Chinese city.

In addition to the new maps, a new SMG called the “Peacekeeper” has been added for multiplayer, and a new zombies mode called “Turned” will allow players to take on the role of zombies themselves.

The DLC will be available first on the Xbox 360. On January 29 fans can download the update via Xbox LIVE for 1200 Microsoft Points.
