Batman's maniacal archnemesis the Joker will be available as a free download for owners of the PlayStation 3 version of Arkham Asylum.
If you've ever wanted to roam Gotham's streets as The Joker, now's your chance. Owners of the PS3 version of Batman: Arkham Asylum will be able to download the character for free on the game's release date, June 23. While you won't be able to play as The Joker in the game's main storyline, the character will be available for Challenge Maps in the game (no details yet on what Challenge Maps are, but we imagine they will take advantage of The Joker's comical variety of skills).
There is no word yet on whether the Xbox 360 version will also have an exclusive character. I wouldn't mind reeking havic as Bane, or Harley Quinn.
