Sony has revealed some details regarding the PlayStation-exclusive content for the forthcoming Batman: Arkham Knight.

PS4 players will be able to take on the sinister Scarecrow, who is using his patented fear toxin to make Gotham even less welcoming than usual:

Gotham falls victim to Scarecrow's fear toxin, transforming the famous city into a twisted, hellish nightmare in the Batman: Arkham Knight Scarecrow Nightmare Pack.

Tear through the city in the all-new batmobile and face off against a towering vision of Scarecrow and his undead army as they spread terror on the streets, available exclusively on Playstation 4.

Arkham Knight is the final entry in Rocksteady's Batman trilogy, and is expected to launch early next year.
