Batman: Arkham City is without a doubt an epic adventure filled with the most illustrious villains to cross paths with the caped crusader. Harley Quinn plans to step up as a force to be reckoned with in the upcoming Harley Quinn’s Revenge DLC pack.

Rocksteady Games says Harley’s revenge will add another two hours of gameplay to Batman’s latest adventure. With Harley as the new boss of Arkham City, she is not please with what Batman has done to Joker. Robin is not one to sit things out and will join Batman in the fight against the leather clad loony.

Is she a real psychopath or just misunderstood? Harley Quinn’s Revenge DLC pack will set things straight on 30 May, 2012. Or, if you can wait until 7 September, the Batman: Arkham City Game of the Year Edition will include all previous maps, playable characters and Batman skins. Harley Quinn’s Revenge will also be bundled into the GOTY Edition.
