Dark Crusade features two new playable races, the Tau Empire and the Necrons, bringing the number of totally unique races to an unprecedented seven. In addition to the two new playable races, Dark Crusade features an all-new single player campaign centering on the conquest of a "meta-map," with each territory captured giving tangible rewards to the occupying force. A greatly expanded multiplayer component and a completely unique economy model for the Necrons presents gamers with the most compelling Dawn of War game to-date.
