Batman Arkham Knight is the explosive, epic finale to Rocksteady's Arkham series, where Batman faces Scarecrow, who unites Gotham's villains (Penguin, Two-Face, Harley Quinn) to take over the city with fear toxin, introducing the fully playable, weaponized Batmobile for the first time in the franchise as Batman fights for his mind and the city's future. The game expands the open world of Gotham, deepens the psychological narrative exploring Batman's psyche with Joker hallucinations, and features a new, militaristic villain, the Arkham Knight, who becomes a key part of the story!
