The Dead World introduces the Empire of the Dead, a new faction that allows players to lead the dead to grim victory or design their own undead armies. Instead of relying on food like mortals, undead empires spread cemeteries, mausoleums, and the bodies of slain enemies to grow their population.

Terrifying new enemies await players in The Dead World. Morrigan the Risen has returned from the buried fortress of Grazna to lead the Empire of the Dead. Powerful Hellknights and the undead, half-spider Risen Brood threaten the frontiers of growing empires.

The Dead World also includes a new hand-crafted map that holds carefully placed secrets to discover. In addition, undead casters enjoy all-new spells including the abilities to feed on the lifeforce of friendly units and raise an undead army anywhere in the world.
