BATMAN: ARKHAM KNIGHT

The Dark Knight returns in a new Batman game this fall. And for the first time ever in the Batman Arkham series, you'll get to drive the Batmobile through the streets of Gotham. 
Batman But it's not just a new Batman game you're playing. It's a whole new Batman. Set one year after Batman: Arkham City, this is no longer a Batman at the beginning of his career.
This is a Batman at the height of his abilities, voiced once again by our favorite Batman ever: Kevin Conroy!

And what would a new Batman game be without some new enemies, including one created specifically for this game: the Arkham Knight. Who is he/she? What kind of plan have they set in motion? How does Alfred get all those stains out of the Batsuit? Hopefully all these questions and more will be answered in Batman: Arkham Knight. And don't forget, you can play as Batman on the PS4, too!
