During the Microsoft conference today at E3, there was a feature announced that the community has been asking for, for quite some time. Backward Compatibility is officially coming to Xbox One but not all games available on the Xbox 360 will be available.
At the moment there are only a select few games that actually utilize the backward compatibility feature and only Xbox preview members can take advantage of the feature right now. Everyone else will be getting the feature some time this year and more than 100 games will be available around the holiday season.
Here is the list of games already available:
Banjo Kazooie: N n B
Geometry Wars Evolved
Perfect Dark Zero
Super Meat Boy
Toy Soldiers: Cold War
Viva Piñata: TIP
