Earlier this year Activision finally released Call of Duty: Black Ops II on the Xbox One via their backwards compatibility program, allowing people to reunite themselves with the game on the latest console.
Today they can reunite themselves with another game published by Activision in the Call of Duty series and that is Call of Duty: Ghosts, which was also launched on the backwards compatibility program, allowing gamers to get back into the game on the Xbox One.
You can download it at no extra cost today if you previously purchased it on the Xbox 360 and if you already still have an Xbox 360 disc you can just pop that into your Xbox One to get started.
Of course, there is already a version that was specifically made for the Xbox One, so you might prefer that.
Alternatively, you can pick it up from the Xbox Store today.
