World of Warcraft: Cataclysm, Blizzard's third expansion for the world's most popular subscription-based massively multiplayer online role-playing game, will be released starting on December 7, 2010.

The expansion will be available on PC and Mac and will also be offered as a digital download from the Blizzard Store. A special collector’s edition packed with bonus items will be available exclusively in retail stores.

The first two World of Warcraft expansions, The Burning Crusade and Wrath of the Lich King, each shattered PC game sales records upon their release. In Cataclysm, the face of Azeroth will be forever altered by the return of the corrupted Dragon Aspect Deathwing. Once-familiar areas of the world that have now been reshaped by the devastation and filled with new adventures. In an effort to survive the planet-shattering cataclysm, two new playable races - worgen and goblins - will join the struggle between the Alliance and the Horde. As players journey to the new level cap of 85, they'll discover newly revealed locations, acquire new levels of power and come face to face with Deathwing in a battle to determine the fate of the world.
