Eidos has confirmed that The Joker will be an exclusive playable character in the PS3 version of Batman: Arkham Asylum.
He'll be free to download from the PlayStation Store, but will only be playable on the Challenge Maps.
Eidos was unable to tell us what treat may or may not await Xbox 360 owners in response. But we'll let you know what we hear.
That's Batman Asylum, then: a superhero game that might finally live up to its licence. Our recent hands-on impressions can tell you why.
Batman Asylum launches in June on PS3, Xbox 360 and PC.
