All I knew previously was that Warhammer is one of those games where people paint little miniature figurines, and that the Warhammer 40k universe is a sci-fi fantasy blend where you can have orks (Warhammer's spelling) in space. Now, thanks to this third and final expansion pack, Dawn of War has become a crazy sci-fi real-time strategy game with a staggering nine armies to play around with--which is a great crash course for the Warhammer 40k universe.
Soulstorm, like previous installments for Dawn of War, is a full RTS game on its own; it has a campaign, multiplayer capability, skirmish mode, and nine armies to choose from. However, when you play in multiplayer, you can only use the Soulstorm-specific armies; to play as one of the other seven armies requires the game that has them (Dawn of War shipped with four, the Winter Assault expansion added one, and Dark Crusade added two)."
