Batman: Arkham City - Exclusive Digital (2011-)

While newly elected Mayor Sharp is the public face of Arkham City, the secret manipulator behind the scenes is the nefarious Dr. Hugo Strange. Sharp presents the walled encampment as Gotham's ultimate solution to crime, but Strange has a secret, darker agenda. He's recruiting his own security force—one that will answer only to him and whose ultimate goal is the death of Batman.
