The game is based in the Warhammer 40K universe. Each player forms a Retinue led by a heroic Inquisitor, a devious Chaos agent or one of a selection of other protagonists. They pit their forces against one or more other Retinues for possession of a chosen objective, or just for the rush of bloody combat.
