Batman: Arkham Knight is now available on Steam again, and Warner Bros. Interactive Entertainment is doing its best to reward players. In a forum post, WBIE announced that players who have already purchased Arkham Knight, or purchase it before November 16 will receive all of the games in the Batman: Arkham library for free.
That’s Arkham Asylum Game of the Year Edition, Arkham Knight Game of the Year Edition, Arkham Origins and Arkham Origins Blackgate. No date has been specified for the games to appear in your Steam library, but WBIE says they are working with Valve to aim for a December target.
Further, WBIE has announced that developer Rocksteady will be creating a new “Community Challenge Pack” for PC and console owners of the game, for free. PC players will receive the pack a week early when it releases in January 2016.
Finally, until November 16, Valve will be running a special contest through Team Fortress 2 to create Batman: Arkham cosmetic items for Team Fortress 2. The winning items will be given to all owners of Batman: Arkham Knight who have purchased the game before November 16.
