Using a great variety of gadgets you must make your way around the island, and the asylums halls to find and stop the joker. The game uses a 3-button combat system, but with a great number of gadget abilites which Batman can unlock. This makes for a very cinematic combat experience when fighting the Joker's goons.
The Joker, Batman's arch enemy, has instigated an elaborate plot from within Arkham Asylum, where many of Batman's other foes have been incarcerated. Batman investigates and comes to learn that the Joker is trying to create an army of Bane-like creatures to threaten Gotham City, and is forced to put a stop to the Joker's plans. Throughout the night, Batman is forced to deal with the temporarily admitted sane prisoners from Blackgate prison, Scarecrow, Zsasz, Poison Ivy, Bane, Killer Croc and Harley Quinn. By the night's end, all the villains, save Bane, Croc and Crane, are recaptured and placed back in their cells and what remains of the staff try putting the Asylum back in order. Though it is thanks to Batman that the criminally insane are brought back under control, administrator of Arkham, mayoral candidate Quincy Sharp, soon takes advantage and claims the credit himself for bringing the Arkham institution back under control.
