Gamespot have announced that Call of Duty: Black Ops for the Xbox 360 is now compatible with the Xbox One. This means that you can now put your Black Ops disc into your Xbox One and play it on there.Idiotproof.
Multi-disc Xbox 360 games are also beginning to be supported, in case you want to play any other games that aren't Call of Duty (but why would you?)
Don't forget - if you want to play Black Ops or any other CoD game with people then drop a request here!
Until next time,implying there'll be a next time
