Batman: Arkham City – Harley Quinn’s Revenge Review | Game Insider

Game Insider: "The DLC’s biggest issue is its existence. Rocksteady, in providing another taste of the city, another lens with which to view it, and another relationship to explore has left more questions and cravings; I wanted to explore Arkham City as Robin, fight alongside Batman in combat, and get to know more about Robin’s origins…one can't help but feel just a little disappointed."
