Rocksteady Studios, the developer responsible for towing Batman's star vehicle out of a muddy Gotham ditch. Rocksteady's Batman: Arkham Asylum debuted in 2009 to critical applause and has since shipped over three million copies.
Jamie Walker, studio director of Rocksteady Games, expressed pride in the deal -- the cost of which has not been disclosed. "We are proud to strengthen our association with WBIE, a world class publisher that we have enjoyed working with since we began developing Batman: Arkham Asylum," he said. In addition, games director and excellent sniper position Sefton Hill noted, "The Rocksteady team is very much looking forward to creating more great games based on widely recognized Warner Bros. brands like Batman."
What Warner license will Rocksteady revive next? Whatever it is, it'll have to wait until construction is completed on the unnamed Arkham Asylum sequel.
[Update: Square Enix Europe (Eidos) has confirmed that it still retains a 25.1 percent stake in Rocksteady.]
