World of Warcraft: Cataclysm

World of Warcraft: Cataclysm is the upcoming third expansion pack for the massively multiplayer online role-playing game (MMORPG) World of Warcraft, following Wrath of the Lich King and The Burning Crusade. It was officially announced at BlizzCon on August 21, 2009; however details were discovered earlier.

In a February 2010 Activision Blizzard investor call, Blizzard CEO Mike Morhaime revealed that Cataclysm would be released in that same calendar year.

The central plot of the expansion is the return of the evil dragon Deathwing the Destroyer. Last seen in Warcraft II, Deathwing has spent the interim licking his wounds and plotting his fiery return from the elemental plane of Deepholm. His return tears through the dimensional barrier with Azeroth, causing a sweeping cataclysm that reshapes much of the world's surface.
