Batman: Arkham Asylum is an original adventure with fast action and large-scale combat sequences, played from a close third-person perspective in a dark, survival horror-styled setting. The game begins as Batman delivers the Joker to Arkham Asylum, Gotham City's psychiatric hospital for the criminally insane. The villain springs a trap and takes over the institution, with an army of thugs and a host of dangerous inmates to back him up. The twisted plot plays out in a freely explored re-creation of the asylum and surrounding island. In addition to prowling the corridors of Arkham, Batman can explore the outdoor areas, using his equipment to reach high spots and glide safely back down.
