Mortal Kombat vs. DC Universe presents coin-op and comics fans alike with the chance to battle through never-before-seen fantasy grudge matches featuring the most powerful characters from Midway's notoriously brutal fighting series and DC Comics' expansive superhero universe. Although it's not the first fighting game to bring together characters from multiple fictional universes, many of the most recognizable DC heroes are playable in head-to-head bouts for the first time here. The roster of 22 playable characters includes Scorpion, Sub-Zero, Sonya, Raiden, and Kano from the Mortal Kombat games, with Batman, Superman, The Joker, Wonder Woman, and Darkseid from DC. Each character has a particular fighting technique, as well as a distinct, Mortal Kombat-style finishing move. The game's "Freefall Kombat" allows fighters to battle as they fall from one level of an arena to another, and the "Klose Kombat" mechanic handles up-close grappling. An expanded single-player campaign follows a storyline in part by comics writers Jimmy Palmiotti and Justin Gray. Unlike earlier Mortal Kombat console games, Vs. DC Universe receives a rollicking T for "Teen" rating from the ESRB.
