As previously reported, the standalone expansion pack is titled Soulstorm. Co-developed by Relic Entertainment and Iron Lore Entertainment for PC, it will bring with it a new campaign and two new payable races, one of which is the Dark Eldar. The other is currently unknown.

News of Iron Lore's involvement with the title does not come as much of a shock, as the Titan Quest developer recently told Shacknews that gamers could expect more action RPGs and RTS titles from the studio.

"In Dawn of War - Soulstorm, we've taken Games Workshop's epic war from one planet to an entire star system," said Relic general manager Tarrnie Williams. "Allowing gamers to play nine unique races, introducing air units and providing multiplayer achievements for the first time creates a tremendous amount of new and challenging strategic gameplay for all players."

Soulstorm hits stores in spring 2008.
