A set of PlayStation 4-exclusive Batman skins for Batman: Arkham Knight, available only on that platform at launch. They are worn by the same Batman navigating the same Halloween night in a Gotham that Scarecrow has emptied of civilians with a fear toxin threat—while the Arkham Knight commands a private militia and a mystery from Batman's past resurfaces through the Joker's legacy. The skins change the look of the character without altering the story.
