So a while back we heard that the Joker would be a DLC for B:AA but now we find out he is going to be free. Eidos Interactive and Warner Bros. Interactive Entertainment are delighted that The Joker will be an exclusive playable character in Batman: Arkham Asylum for the PlayStation®3 computer entertainment system. The character will be made available upon release as a free downloadable character through PlayStation®Network for the PLAYSTATION 3 and can be played in Challenge Maps from the game. Sweet!!
