Batman: Arkham City

Batman: Arkham City is an upcoming sequel to Batman: Arkham Asylum.

Plot
One year after the events of Arkham Asylum caused by the Joker occurred, Quincy Sharp took full credit for ending it. This has gotten him a lot of support from the city-officials and has resulted in him becoming the mayor of Gotham City. His first act in office is declaring that Arkham Asylum and Blackgate Prison are unfit to hold the inmates. He then proceeds to buy off a portion of Gotham City and names it "Arkham City." He places walls around the city and contracts a group named "Tyger" to guard it. "Tyger" is an enemy to the villains of Arkham, Blackgate and Batman. Then, Quincy Sharp announces that there is only one rule: “Don’t try to escape, for the penalty for this action is death." In this case, the prisoners in Arkham City are free to do whatever they want to besides escaping incarceration, but things get homely when Professor Hugo Strange becomes in charge. However, Batman believes this is a ticking time-bomb and subsequently keeps a watchful eye on Arkham City, looking for any excuse to break into it. Eventually, Two-Face gets incarcerated in Arkham City and realizes that he needs to make a huge impact on the other inmates to prevent himself from being defeated. He then captures Catwoman and proceeds to announce an execution, believing this will accomplish his goal of making him a powerful figure in Arkham City. Given their past, Batman has no choice but to enter the prison to save her and uncover what's really going on. With a brand-new bag of tricks, he might just survive the night.
