"Batman: Arkham Asylum is an action-adventure stealth video game based on DC Comics' Batman for PlayStation 3, Xbox 360 and Microsoft Windows. It was developed by Rocksteady Studios and published by Eidos Interactive in conjunction with Warner Bros. Interactive Entertainment and DC Comics. The PS3 and Xbox versions of the game were released on August 25, 2009 in North America and August 28, 2009 in Europe, and the PC version was released on September 15 in North America and on September 18 in Europe.
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 archenemy, 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 that threaten Gotham City, and is forced to put a stop to the Joker's plans. The game's main characters are voiced by actors from the DC animated universe, namely Kevin Conroy, Mark Hamill, and Arleen Sorkin reprise 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.
The game received extremely high praise from critics, earning a 92% average on GameRankings, a game aggregator. This also earned it a spot in the Guinness World Records for "Most Critically Acclaimed Superhero Game". Sales were also high, selling over 2 million copies within its first two weeks of its console release."
