That’s because, like the second expansion Dark Crusade, Soulstorm is a stand alone product – unlike some expansions for other games it’ll work without the need for you to have the title proper. While there’s little doubt that gamers who already own Warhammer 40,000: Dawn of War will find Soulstorm of most interest, you don’t have to have the main game installed on your hard drive in order to play the upcoming expansion.
