Warhammer 40,000: Dawn of War III

In a return to the massive battles from Dawn of War I, DoWIII takes the series back to its roots with a base-building RTS that now adds gigantic war machines like the Imperial Knights to the battlefield. New features include DLC and collectible, customizable elite units. In addition to multiplayer and coop modes, players will play a three faction campaign that alternates missions between the player controlling the Space Marines, Orks and Eldar. (Source: User Summary)
