Rocksteady's Batman: Arkham series is widely recognized as one of the most influential superhero games ever made, thanks to its innovative approach to combat and stealth as well as its engaging overarching narrative. More recent superhero titles, like Insomniac's Marvel's Spider-Man franchise, have even gone on to utilize some of Batman: Arkham's best features. Now, Rocksteady has just released its highly anticipated Batman: Arkham spin-off, Suicide Squad: Kill the Justice League.
