This mod adds some new winconditions to Dawn of War: Soulstorm. If activated they offer you a totally new mode of gameplay, that may remind you a bit to the Dark Eldar stronghold mission in the Soulstorm campaign. So you will start the game with a bunch of units and without a base, too. Then you have to discover the terrain and find cages controlled and defended by a Dark Eldar player. By destroying a cage you will free a prisoner joining your or your allies SaR team. If players rescue all their prisoners, then they have to bring them back to the drop point to get back up. A team wins by accomplishing this or by killing all enemies SaR teams - except the builders… But there are the "Campaign Buildings"-winconditions, too. If activated each wincondition will spawn the corresponding kind of building randomly on the map. These buildings are each assigned to a strategic point and you can get control over them by capturing this point. In consequence you will get some advantages.
As you can see in this picture, prisoners can also be squads, which you cannot build in a normal game.
