Microsoft have announced that the Xbox One will now support backward compatibility, enabling gamers to play Xbox 360 games on their Xbox One console. The new feature will be available later this year with a limited number of Xbox 360 games being supported initially.
If you want to play Xbox 360 games on your Xbox One, there are two ways of doing so. If you have purchased your games digitally via Xbox Live, it’s as easy as logging in and re-downloading the game onto your Xbox One console without any additional fees. If on the other hand you own a physical copy on a disc, you will need to download the game onto your Xbox One hard-drive.
Microsoft have promised that over 100 titles will be available at the start with hundreds more receiving backwards compatibility in the future. A full list of supported games has not been released yet by Microsoft so stay tuned for any updated from E3! They also stated that 360 games will be able to take advantage of the Xbox One hardware, with Mass Effect being shown running on the Xbox One. Xbox 360 games will also be able to take screenshots, a feature only available on Xbox One.
