Activision World of Warcraft: Cataclysm Expansion Pack PC

You've toppled the undead armies of the Lich King and brought Arthas to his knees. Now the breaker of worlds, Deathwing, has burst forth from the heart of the Maelstrom and unleashed his rage upon the land and sea. Azeroth has been changed forever, and you must enter the elemental planes in an epic quest to stop the Destroyer from shattering the world itself.
