Batman: Arkham Asylum and Arkham City developer Rocksteady Studios will next tackle a prequel tale featuring Batman and the DC Universe's Justice League.
The title will be set before Rocksteady's existing series, detailing Batman's first meeting with the Joker.
Set during DC's Silver Age of comicbooks, the Dark Knight will form the Justice League of America with other heroes such as Superman, Wonder Woman, Green Lantern and the Flash, Variety reports.
The game won't launch before 2014 "at the earliest", suggesting Rocksteady is developing the title for the next generation of console hardware.
Warner Bros. is apparently keen to promote other DC characters within Rocksteady's series as it readies new film incarnations of Superman and other Justice League members.
Eurogamer has contacted Warner Bros. for comment on the report - we'll update if we hear back.
