Developing: Next Batman game a Silver Age Arkham Asylum prequel.

Variety is reporting that the next Batman from Rocksteady, makers of the Arkham series, is going back to the chromatic ’50s. 

New, highly stylized title is being developed as a prequel that revolves around Batman’s first meeting with the Joker. It’s based on the Silver Age of DC’s comicbooks from the 1950s when the Caped Crusader teamed with other heroes like Superman and founded the Justice League of America.

Sources are vague, but it makes sense following the rampant success of the Avengers mashup.
