Batman: Chaos in Gotham

Batman: Chaos in Gotham centers on the aftermath of a mass breakout from Arkham Asylum. The city's most notorious criminals, such as Poison Ivy, The Penguin, and The Joker, are each causing distinct forms of trouble, leaving the police unable to respond.

While Batman is the primary hero tasked with stopping these villains and returning them to custody, he is not alone. Robin and Nightwing appear in the story, though Batgirl is the only other character a player can directly control. The campaign builds toward a confrontation with a final mystery antagonist whose identity is concealed until the end.
