In Batman: Arkham Asylum, BATMAN finds himself trapped inside the confines of Gotham’s psychiatric hospital for the criminally insane, ARKHAM ASYLUM. The Joker has set a trap for the DARK KNIGHT and has conspired with the deranged inmates to eliminate Batman once and for all.

Gamers will move in the shadows, instil fear amongst their enemies and confront The Joker and Gotham City's most notorious villains, including HARLEY QUINN, BANE, KILLER CROC, POISON IVY and SCARECROW, who have taken over the asylum.
