Four years have passed since the aftermath of Warcraft III: Reign of Chaos, and a great tension now smolders throughout the ravaged world of Azeroth. As the battle-worn races begin to rebuild their shattered kingdoms, new threats, both ancient and ominous, arise to plague the world once again. World of Warcraft lets you assume the roles of Warcraft heroes as they explore, adventure, and quest across a vast world. Thousands of players can interact within the same world. Whether adventuring together or fighting against each other in epic battles, you'll form friendships, forge alliances, and compete with enemies for power and glory.
