Warhammer Online

Warhammer Online: Age of Reckoning (officially abbreviated as WAR) is an massively multiplayer online role-playing game based on Games Workshop's Warhammer Fantasy setting. It is developed by Mythic Entertainment and was released simultaneously in North America, Europe, Asia, Australia and New Zealand on September 18, 2008. The game features 22 different player careers each one unique to one of 6 different armies.

The game revolves around the continual worldwide conflict that the Warhammer Fantasy setting is known for, and the game will be geared toward ongoing, constant war.

The Age of Reckoning is a time of war within the Warhammer universe that exists outside the currently established time lines for the sole purpose of the setting of the game. It is a time of massive conflict, the result of the Fall of Karak Eight Peaks to Grumlok and Gazbag with the Greenskins, the Decimation of Praag by the Chaos who are lead by Tchar'zanek, and the attack lead by Malekith in the assault on Lothern against the High Elves.
