Wrath of the Lich King Classic is rapidly approaching its release date of Sept. 26, and World of Warcraft fans can dig into the nostalgic re-release with a pre-expansion patch setting the stage starting on Aug. 30.
The Invasion runs until Sept. 26, when Wrath of the Lich King goes live and players can travel back to Northrend to the Howling Fjord or Borean Tundra.
Players can travel to Necropolis throughout the world of Azeroth and defeat waves of Scourge that spawn from crystals.
On Sept. 6, the Zombie Plague event begins, which spreads the mysterious Scourge affliction through capital cities.
