Microsoft has officially confirmed Xbox One Backward Compatibility, implying that some Xbox 360 games can be played on the current-gen console. The announcement was made during the Xbox press conference at the ongoing E3 by Xbox Head Phil Spencer.

At launch, the new system will have support for over 100 titles, while more will be added in the future. The compatibility feature will work both on discs as well as digital copies. Digital downloads will start showing up automatically, while for physical discs, the game still needs to be downloaded.

“This fall, we’re launching Xbox One Backward Compatibility so you can play select Xbox 360 games on Xbox One. Best of all, Xbox One Backward Compatibility will be available at no additional charge, so you won’t have to pay to play games you already own. Not only is backward compatibility one of the most-requested fan features, it’s also part of our vision to provide the biggest and best games catalog without limits, so you can get more out of the investment you’ve made in your game collection, and your games library is not limited to just one device,” said Xbox.

The company says that they have built special Xbox 360 simulator for the new console, which allows it to run older titles.

“To play one of the supported titles listed above that you already own, simply go to My Games and Apps and download the game to your Xbox One. Or put the disc in the drive, install the game and start playing,” explained Xbox in a blog post.

Microsoft says not all Xbox 360 titles will be available at launch. Though the company has devised a system based on fan feedback and would ask publishers to make their games available. However, Kinect games will not be supported.

Xbox One Backward Compatibility feature is now available for members of Microsoft’s early release Xbox One preview scheme, while a full rollout is expected by the end of the year.

The Xbox One maker also announced that Xbox One preview program members who are also part of the Windows Insider Program, will be able to use a streaming feature that mirrors their Xbox One dashboard to their Windows 10 tablets and PCs. Along with the streaming functionality, users can also access friends list, achievements, Party Chat, Snap Mode and more.

Meanwhile earlier, Microsoft also announced a redesigned user interface for the Xbox One along with the integration of Cortana on the Xbox One.
