Steam News has word on a new update that's automatically available for Painkiller Resurrection adding Tower of Power, a Steam-exclusive co-op map, to the shooter sequel. Word is: "The Tower of Power is not a battle arena for puny humans, but indeed the proving ground for all of those demons which want to become one of Lucifers [sic] generals. They have to fight their way through a wasteland of burnt demon corpses and lava, a place, where each step can be your last."
