World of Warcraft: Cataclysm

World of Warcraft: Cataclysm is the third expansion set for the massively multiplayer online role-playing game (MMORPG) World of Warcraft, following Wrath of the Lich King. It was announced at BlizzCon 2009 on August 21, 2009, though details leaked earlier. It adds a substantial amount of content to the game world, including two new races (Goblins for the Horde, Worgen for the Alliance), new race/class combinations, entirely redesigned zones, flying mounts in Azeroth and guild levelling and achievements. It also raises the level cap to 85.
