Eidos Interactive and Warner Bros. Interactive Entertainment can today confirm that Batman: Arkham Asylum will be released at the end of summer 2009. This additional time will allow us to ensure Batman: Arkham Asylum is of the highest quality for gamers.

First the news of The Joker being a PS3-exclusive character, and now this? Either way, we also have a new video entitled, “FreeFlow Combat.” The trailer showcases Batman utilizing the FreeFlow combat system to chain together unlimited combos seamlessly. The same system also allows you to battle with huge groups of The Joker’s henchmen in brutal melee brawls.
