THQ and Relic Entertainment today announced that a second expansion pack for Warhammer 40,000: Dawn of War is in development. Due for this release this fall, "Dark Crusade" will add the Tau Empire and the Necrons as playable races. The expansion also features a new singleplayer campaign and new multiplayer options.

"With Dark Crusade we have taken a very different and exciting route with the single player game, allowing the player to conquer the globe as any of the seven unique playable races," said Ron Moravek, vice president THQ, general manager Relic Entertainment. "The Dawn of War franchise has become synonymous with innovation and attention to detail and we have drawn on the extensive knowledge base that Games Workshop's exhaustive universe provides us with to bring classic Tau and Necron combatants to the battlefield on Kronos."
