Batman™ is sure The Joker™ is up to no good so defy Barbara Gordon’s warnings and enter the huge Arkham Asylum! Dash past the police car and through the x-ray security scanner at the entrance. Sneak past the GCPD officers, the head of the ward Aaron Cash and Dr. Harleen Quinzel™. Watch out for the inmates exercising in the yard or eating in the canteen. Track down The Joker™ and send him far away to the Phantom Zone with the Phantom Zone Projector!
