When part of Gotham is turned into a private reserve for criminals known as Arkham City, all hell is sure to break loose, and the Dark Knight is the only one who can stop it.
During one of Hugo Strange's game-over screens, he will say "So, you failed to live up to his expectations. How predictable." It isn't explained who the "his" is, but it seems likely that he is talking about Quincy Sharp, who believed Batman to be some sort of worthy successor for his work. He's actually talking about Ra's Al Ghul.
Bruce? Where the hell have you been? I thought you were dead.
Batman: Sorry to disappoint you.
The Deadshot side mission ignores all the laws of physics to justify the assassin's ridiculous kill shots. When Batman is hunting Deadshot, his second victim is sniped through a full water tower. Even assuming there was a gun that could still be lethal after shooting through 6 feet of water (and MythBusters confirmed there is not), the bullet's trajectory is completely unaffected. All of Deadshot's bullet trajectories follow straight lines instead of parabolic arcs like they do in real life. Deadshot's bullet trajectories are determined using only a single point of impact, which is impossible. Indeed, the trajectory of Joker's bullet can only be traced using the bullet hole on the floor and the hole in the window. One of Deadshot's victims is killed by a bullet ricochet, something the MythBusters also proved to be impossible.
During the closing credits, the Joker is heard singing "Only You" to Batman.
