Really great game combines all of the Justice league and gives them a bad side, because the game play takes place in a alternate universe were the main villain is superman and the hero is joker. but dose give a really good back story as to all super hero games combines a story line game to a mortal combat type game in simple terms, the downloads and upgrades are pretty nice, as well as the many different stories you can unlock by playing each super hero or villain.
over all the only better game then this is part 2
