Update: Call of Duty: Black Ops added. The Xbox 360 Games Backwards Compatibile with Xbox One Retail List18 May 2016
With the 12 November 2015 Xbox One Console OS update over 300+ Xbox 360 games have now become compatible to play on your Xbox One Console.
Xbox One Backward Compatibility is easy to use
The digital tiles that you own and are part of the Back Compatible game catalog will automatically show up in the “Ready to Install” section on your Xbox One. For disc-based games that are a part of the Back Compatible game catalog, insert the disc and the console will begin downloading the game to your hard drive. After the game has downloaded to your hard drive, users will still need to keep the game disc in the drive to play.
Below is the current Full Retail Xbox 360 Games which will now work on your Xbox One.
Also check out the Official Xbox Backward Compatibility Page.
Note: Xbox One Games won't work on Xbox 360.
