Quantum Break for Xbox One has additional content compared to the releases for other platforms. For that platform it is only available as a bundle of two Remedy Entertainment's titles.
For Xbox One and Windows the live-action episodes which are used as story backbone are streamed. For Xbox One it is also possible to optionally download Quantum Break: Episode Pack as optional DLC to store the video content locally instead of streaming. These episodes have different scenes based on the player's choices in the game. The episode pack takes up 75 GB (almost twice the size of the installed base game).
The games are played on the Xbox 360 or one Xbox One via backward compatibility. Unlike the Windows release every copy on Xbox One release of Quantum Break includes a digital copy of Alan Wake and its add-ons. For digital release purchases, buyers were emailed the DLC code while the retail release includes DLC codes in the package.
Quantum Break is not available for the Xbox 360. The platform is only listed here because the bundle of Alan Wake and the two DLC items is provided for the Xbox 360 through this release.
