Originally released around 2010, “Firestorm Over Kronus” (now merged with “Firestorm Over Kaurava for “Dawn of War: Soulstorm” and retitled “Purgation of Kaurava”) is a total overhaul mod for “Dawn of War: Dark Crusade” that seeks to completely overhaul the game in order to bring it closer to Games Workshop’s beloved tabletop.
