Sony has revealed new details on Batman: Arkham Knight's PlayStation 4-exclusive content, the Scarecrow Nightmare Pack.
The add-on will re-introduce the Batman: Arkham Asylum villain after his absence in Arkham City.
"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," a description on PlayStation.com reads.
"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."
We first got a glimpse at Scarecrow during gameplay footage shown off at the end of Sony's E3 2014 press conference.
"How many bones will you crush? How many lives will you destroy in pursuit of what you call justice?" Scarecrow growled. "You are the product of everything you fear - violence, darkness, helplessness. All that remains is for you to watch while I drag your beloved Gotham into oblivion."
With this content being platform-exclusive, it's unclear to what extent Scarecrow will feature in the game on other formats.
We've asked Warner Bros. for more information.
