Batman: Arkham City

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

Plot
It's been one year after the events of Arkham Asylum and Quincy Sharp has taking full credit for ending The Joker's reign of terror on Arkham Island. This has gotten him a lot of support from the city officials of Gotham and has resulted in him becoming Mayor of Gotham City. His first act in office he declared that Arkham Asylum and Black Gate Prison are unfit to hold the inmates. He then proceeds to buy off a portion of Gotham city slums and names the area Arkham City. He walls of the entire City and contracts a mercenary group named Tyger to defend the perimeter of the City. Sharp announces that there is one rule and one rule only: “Don’t try and escape” the penalty for this action is death. This though is the only rule of the City. Prisoners are free to do what ever they wish and with Hugo Strange now in charge things get messy.

Batman believes this is a ticking time bomb and has been keeping a watchful eye on Arkham City for months now, looking for any excuse to break into the well-guarded prison city.

Recently Two-Face gets put into Arkham City and realizes he needs to make a huge impact on the current inmates to prevent himself from being eaten alive. He then captures Catwoman and proceeds to announce an execution; believing this will accomplish his goal of making him a powerful figure in the City.

Given their past, Batman has no choice but to enter this hellish domain to save her and uncover what's really going on. With an all-new bag of tricks, he may just survive the night
