Although a sequel was already announced to the hugely successful Arkham series, it seems Warner Bros. has finally given title and release date of next Game in series.
The game is going to be a prequel to the other games (which more people really need to play) and is apparently set in the silver age of comics as opposed to golden age of previous games. The game will follow a younger Batman who is still learning the ways of crime fighting and hasn't quite acquired his current convictions made popular by previous Arkham games and Christopher Nolan's film series.
Allies of Batman: James Gordon and Alfred Pennyworth.
Enemies: Black Mask, Deathstroke (Slade from Teen Titans), Penguin (again), and Alberto Falcone.
Reply if you're a fan of the series and want to discuss the future! Arkham City wast favorite game since Resident Evil 4 so I'm definitely rooting for this series to continue its success in the future.
