Included are the Millennium and Infinite Earths Skin Packs, which each feature five new costumes for Batman and one for Robin. The Gotham By Gaslight and Brightest Day packs deliver two additional Batman skins, while the Initiation DLC pack allows players to battle the forces of evil as Bruce Wayne. Most notably, the Season Pass also grants access to an as-yet unnamed expansion pack which is said to expand the plotline found in Batman: Arkham Origins.
Batman: Arkham Origins debuts on the PlayStation 3, PC, Wii U and Xbox 360 on October 25. The Season Pass should appear at the same time.
