Activision has announced that the "Revolution" map pack, easily the most exciting DLC yet for Black Ops 2, will be released first on Xbox 360 (as usual) on Jan. 29. "Revolution" contains four new maps, one new Zombies map, a new Zombies mode, and a bonus weapons for multiplayer, apparently a first for the series, according to Activision.

A press releas sent out this week described the new maps, which each have some unique attributes:

"Downhill" is set in the ski country of the French Alps, where players fight their way down the slopes and through a ski lodge, while avoiding the moving hazards of the mountain's gondola system. Opponents must dodge the floodwaters in "Hydro" as they contend for dominance of this hydroelectric dam facility in Pakistan, filled with treacherous spillways. "Mirage" pits players in competition amidst the sand dunes of a dilapidated luxury resort in the sandstorm-devastated Gobi Desert, where a range of long-distance and close-quarters combat will mix up the action for all play styles. Finally, "Grind" transports players to the historic birthplace of skateboarding, California's Venice Beach, where they will battle it out through the ramps and half-pipes of this massive, epic skate park in a multiplayer environment comprised of unique curved architecture requiring players to adapt and learn new ways to take cover.

In addition, the new Zombies map, "Die Rise," "transports players to the Far East, where they will attempt to overcome a zombie infestation inside a series of collapsed skyscrapers towering over the remains of an obliterated Chinese city" and "wield powerful, upgradable Wonder Weaponry as well as combine new buildable devices to fight a relentless army of the undead throughout Escher-esque sceneries over a deep and perilous chasm."

The new mode is called "Turned," and it puts a twist on Zombies mode by allowing players to take direct control of the undead. Finally, the new weapon is the "Peacekeeper," a "powerful SMG."

"Revolution" will cost $15 when it launches on Xbox Live. Season pass holders get it for free. PS3 and PC versions should follow in the subsequent weeks.

Interestingly, Activision also noted that as of the time they wrote the press release announcing "Revolution," players had engaged in over 427 million hours of multiplayer gameplay since Black Ops 2's launch. Holy shit, right?
