Valve today announced a partnership with Ubisoft for launching Dark Messiah of Might & Magic via Steam. The game will be released this October and carries a SRP of $50. The game will introduce players to the world of Ashan, the new setting for all future Might & Magic games. Ashan is a dark and unforgiving world, scarred by a bloody history and threatened by an apocalyptic prophecy: the Dark Messiah. Players will have the choice to become expert warriors, mages or assassins, each with their own cache of devastating weapons and spells to use in battling huge and vicious enemies. Through combat, players will unlock new skills and equipment. We have a single-player demo that you can download here, so try it now if you haven't done so yet.
