World of Warcraft: Cataclysm je masivní multiplayerové RPG z roku 2010, kde se Azeroth dramaticky mění s návratem Deathwinga. Hráči prozkoumávají nově přetvořené zóny, osvojují si nové rasy (Worgen a Gobliny) a využívají nové prvky jako létání v původních oblastech a profesi Archeologie. Příběh se soustředí na odvrácení apokalyptické Hody soumraku a řešení frakčních sporů.
At the peak of his insanity, Deathwing the Destroyer fought to drive the world into twilight - a devastated future bereft of all life. The Dragon Soul, a powerful artifact lost in the past, was the only weapon capable of truly stopping Deathwing, and so the guardians of Azeroth - the Dragon Aspects - sent a number of valiant heroes racing through time to retrieve it. Despite being attacked by the mysterious Infinite Dragonflight as they travelled the timeways, the champions returned the artifact to the present and delivered it to the wise shaman Thrall. With his aid, the Dragon Soul was deployed against the Destroyer during a brutal battle that began in Azeroth's skies and continued into the roiling heart of the Maelstrom at the center of the world. Through the combined efforts of the Aspects and their allies, the madness of Deathwing was finally brought to an end.
After a ferocious series of battles, Azeroth's heroes banished Ragnaros the Firelord and his elemental minions from Mount Hyjal. Yet, threats to Hyjal persisted, including traitorous druids who had abandoned their allies and joined forces with the elementals. Fearing another elemental invasion, the defenders of Azeroth made a daring assault into Ragnaros' blazing realm: the Firelands. Among the seething flames of this elemental domain, Ragnaros was at his most powerful; only the greatest champions of the Horde and the Alliance, aided by druidic champions like Malfurion Stormrage, could dare hope to defeat the Firelord.
Alarmed by the terrible losses of life among all trolls, the Zandalari tribe traveled around the world to reunite their race and rebuild their once-powerful empire. The Zandalari restored the fallen cities of Zul'Gurub and Zul'Aman, and begun to conduct bloody raids on territories that had once been "theirs." The burgeoning troll force hoped to lead a great war against the other races of Azeroth, but the honorable Vol'jin of the Darkspear tribe stood against their murderous agenda, and recruited champions from both the Horde and the Alliance to invade the ancient cities and stop the onslaught.
