If you already own (or decide to buy) these games, they’ll show up in the Ready to Download area of the My Games and Apps section on your Xbox One. You can download and play them like any other game.
There are now more than 170 games in the Xbox One’s backwards compatibility library. You can see all of the Xbox 360 games you can currently play on an Xbox One here.
New games are added to the mix whenever they are ready, not on a set schedule. There are five games confirmed to be coming to the program but not delivered yet. These are Call of Duty: Black Ops, BioShock, BioShock 2, BioShock Infinite, and Skate 3.
