Eidos Interactive and Warner Bros. announced today that gamers will get a chance to play as the Joker in Batman: Arkham Asylum - but only if you buy the PS3 version.

Once the game launches, you'll be able to download a file off PSN allowing you to play the infamous trickster in the standalone Challenge Maps. Nope, you can't play him in the single-player campaign. He's the ultimate villain of the campaign so that would've gotten a bit confusing.

Arkham Asylum will be released in June for the PS3, Xbox 360, and PC.
