World of Warcraft: Cataclysm is the upcoming third expansion set for the massively multiplayer online role-playing game (MMORPG)World of Warcraft, following the last expansion Wrath of the Lich King. It was officially announced at BlizzCon on August 21, 2009, although details were discovered earlier. On October 4th, Blizzard officially announced the release date of December 7, 2010.
Much content is expected for release in the new expansion including two new races, Goblins for the Horde and Worgen for the Alliance, new and revamped zones, new quests and dungeons, new raids and game mechanics. There will also be new class builds for all races.
The primary feature of the Cataclysm expansion is the redesign of the two continents of Azeroth—areas introduced with the launch of World of Warcraft in 2004. Major changes are being made to both the environment and quests of these zones.
