Gameplay features real-time strategy interaction. It is a stand-alone game and does not need the original Dawn of War disc to run, but players must have the prior games installed and valid cd-keys in order to play as anything but the two new factions online. Like its predecessors, Soulstorm is based on Games Workshop's tabletop wargame Warhammer 40,000, and introduces a multitude of new features to the Dawn of War series, including two new playable factions in the form of the Imperial Sisters of Battle and the Dark Eldar.
Warhammer 40,000: Dawn of War – Soulstorm is the third expansion to the real-time strategy video game Warhammer 40,000: Dawn of War, developed by Iron Lore Entertainment.
