Soulstorm is something of the redheaded stepchild of the Dawn of War family, but it really isn't that bad of a game. It's most damning characteristics are it's glitches and it's pathfinding. But any and all performance issues and wasted potential are remedied by the Ultimate Apocalypse mod. Seriously, it's great, go get it. The mod, that is. The base game itself is okay and provides an enjoyable enough experience, but you'll get the most bang for your buck if you use Ultimate Apocalypse.
