The Batman: Arkham Knightseason pass will include all content for the game, including the packs exclusive to specific retailers.
The news was confirmed on a post on the Warner Bros. forums, following initial confusion from concerned gamers.
The post reads: “Throughout the 6 months of additional Batman: Arkham Knight content, Premium and Season Pass owners will receive all in-game content that is offered through various retail pre-order incentives. This includes the Harley Quinn and Red Hood Story Packs, as well as any Batmobile or Booster Pack that was available as early bonuses for pre-order of the game.
“For those who did not receive the content with their game, these items will become available when their respective exclusivity windows expire in August/September.”
The post concluded: “The tl;dr version of this is: Premium Edition & Season Pass owners will receive all retail exclusive DLC after their respective early access periods expire.”
Batman: Arkham Knight is released on the PlayStation 4 and Xbox One on Tuesday, June 23rd, 2015.
