Batman: Arkham Asylum is a 2009 action-adventure video game developed by Rocksteady Studios and published by Eidos Interactive in conjunction with Warner Bros. Interactive Entertainment. Based on the DC Comics superhero Batman, and written by veteran Batman writer Paul Dini, Arkham Asylum is inspired by the long-running comic book mythos. In the game's main storyline, Batman's archenemy, the Joker, instigates an elaborate plot to seize control of Arkham Asylum and trap Batman inside with many of his incarcerated foes. With Joker threatening to detonate hidden bombs around fictional Gotham City, Batman is forced to fight his way through the asylum's inmates and put an end to the Joker's plans. Most of the game's leading characters are voiced by actors who have appeared in other media based on the DC Animated Universe; Kevin Conroy, Mark Hamill, and Arleen Sorkin reprised their roles as Batman, the Joker, and his sidekick Harley Quinn respectively.
