Playing backwards compatible games online.

Hi

This is not true the Xbox One can play quite a few Xbox 360 games through backwards compatibility. Please note the console needs to be online to allow it to download the backwards compatible version of the game.

Black Ops is backwards compatible so it will work on the One, but MW2 is not. You can see all games that are backwards compatible here - https://majornelson.com/blog/xbox-one-backward-compatibility/

You can play Black Ops online on the One and you would be playing with 360 and One players.

Gold is required to play online on the Xbox. So even if it's a free-to-play game, you still need Gold to play online.

As far as the games you have on Disc, you would not get the remastered ones for free, but if they are backwards compatible you can use the discs to play on the Series X (https://www.xbox.com/en-US/xbox-one/backward-compatibility?xr=shellnav)
The Series S will not have a disc drive so backwards compatible discs will not work and the games would have to be purchased digitally.

If i remember it is a backwards compatible game,just the online wont work as the servers were shut down.

Do you have an official hard drive in your console? If not then you will need one to play backwards compatible games.

Hi, no there is no workaround for this. You have to be online to install a backward compatible game, due to the fact that it is the full backward compatible game that downloads from Xbox Live, not just the patch, this is because the game also includes the
emulator to be able to play the game on the Xbox One.
