Like its predecessors, Warhammer 40,000: Dawn of War - Soulstorm will be a standalone expansion, playable with or without previous iterations; and this time containing 2 new playable factions, one of which is the malicious Dark Eldar, bringing the grand total to 9.

The new chapter will feature an entire intergalactic campaign, spanning not just a planet, but an entire star system - building on the revolutionary meta-game from Dark Crusade. Soulstorm will also introduce air units, additional units for the existing 7 races, and multiplayer achievements to boot.
