Batman: Arkham Asylum is a 2009 action-adventure video game based on DC Comics' superhero Batman.
Arkham Asylum, written by veteran Batman writer Paul Dini, is based on the long-running comic book mythos, as opposed to most other Batman games, which are adaptations of the character in other media besides the source material. The Joker, Batman's arch enemy, has instigated an elaborate plot from within Arkham Asylum, where many of Batman's other villains 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. The game's main characters are voiced by the actors from the DC Animated Universe, namely Kevin Conroy, Mark Hamill, and Arleen Sorkin reprising their roles as Batman, the Joker, and Harley Quinn, respectively. The game is played as a third-person perspective action-adventure game with a primary focus on Batman's combat abilities, his stealth and detective skills, and an arsenal of gadgets that can be used in both combat and exploration.
