Details of Batman: Arkham Knight's-exclusive content on PlayStation 4 has been revealed.
The game's product listing on PlayStation shares details on the content:
"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."
Fans got a glimpse of Scarecrow in Arkham Knight during Sony's E3 press conference, delivering a bone-chilling monologue:
"How many more bones will you crush? How many lives will you destroy in pursuit of what you call justice? You are the product of everything you fear; violence, darkness, helplessness. All that remains is for you to watch as I drag your beloved Gotham into oblivion."
Batman: Arkham Knight's launch date was apparently outed as February 24, 2015 earlier this week, but as yet the only confirmed window is 2015.
