TL;DR: go to Xbox.com
[Update:To clarify, while you’re able to’t purchase DLC via your Xbox One, youcanstill buy Xbox 360 DLC via the 360 store, or via Xbox.com.]
Microsoft has detailed how DLC will work for thosebackward compatible Xbox 360 games.
“Right now, Backward Compatibility does not emulate the Xbox 360 store and new Xbox 360 games can be purchased on your Xbox 360 or via Xbox.com,” a Microsoft representative said toGameInformer. “We will support both digital and disc-based entitlements for Xbox 360 games running on Xbox One.”
Which is a fancy way of saying if you already own the DLC from when you first played the game on Xbox 360, all your DLC should be ready and waiting for you … but if you didn’t pick up the add-on the first time around, you won’t be able to buy it via the Xbox Store on your Xbox One.
If you do have DLC and are not sure where to find it to download, head to ‘Ready to Install’ for each game and click on ‘Manage Game’ to access any pre-bought add-ons.
