Activison announces the Xbox 360 exclusivity of the Revolution DLC for Call of Duty: Black Ops II will end on February 28th with the release of the pack for the Windows and PlayStation 3 editions of Treyarch's Cold War shooter sequel. Here's word on the four new multiplayer maps this adds:

• Hydro: Located in Pakistan, this hydro-electric plant comes complete with a lethal spillway that floods with very little warning.
• Grind: Set in a skate park in Venice Beach (the birthplace of skateboarding!), quarter-pipes and curved surfaces drive players away from easy cover and into intense firefights.
• Downhill: A ski resort in the French Alps, this snowy map is complete with a moving gondola system that can both offer cover and crush you to death.
• Mirage: Located in China's Gobi Desert, this luxury resort has been ravaged by a sandstorm.

Zombies fans get a terrifying double-dose of undead action in Revolution. First, the new map, "Die Rise," drops players inside a maze of crumbling skyscrapers amidst a ravaged Chinese city, where all-new Wonder Weaponry will play a crucial role as they make a valiant stand against the impending zombie hoard. Additionally, Revolution's new Zombies mode, "Turned," flips this new fan-favorite mode around, allowing players to become the undead and play as a zombie, offering an entirely new style of bragging rights.

Fans can either purchase Revolution as a standalone Map Pack for a suggested retail price of $14.99, or they can purchase the Call of Duty: Black Ops II DLC Season Pass. Season Pass holders not only get all four epic DLC Map Packs** for the discounted suggested retail price of $49.99*, but they also get the Nuketown Zombies bonus map, plus an exclusive in-game calling card.
