Batman Arkham Asylum is the first game in the Batman Arkham Series. The game is about the Joker's attempt to escape from Arkham prison and build an army to take over Gotham City. In the series Joker is very different from his role in The Dark Knight. The Joker weapon in Dark Knight is not used, but the Joker in the Arkham series uses a weapon. This Joker in the Arkham series is pretty crazy and obviously a bad guy. The game attracted a lot of attention and was liked by users. It has received very good grades by review sites.
