xbox backward compatible


Microsoft has announced that the Xbox One will receive backwards compatibility with Xbox 360 games, starting later this year.It means that owners of both physical and digital copies of last-generation console games will be able to play them on the Xbox One and there’s no work required on the part of developers, meaning you’ll likely see a whole lot of titles become compatible with your console.
The inability to play games from Xbox 360 or PS3 titles on newer, current generation consoles has been one of the biggest complaints from gamers since the PS4 and Xbox One were announced back in 2013. Microsoft has resolved this on at this year’s E3, announcing backward compatibility, with over 100 titles available this holiday. Though it’s unclear which titles are currently supported.
Furthermore, the new feature won’t just benefit owners of digital Xbox 360 games, but also those with physical copies. According to Microsoft, you’ll simply slide in the Xbox 360 disk and a digital version of the game will start downloading.
Developers won’t need to actively port their games over to the current generation system, but will simply have to approve their titles for backwards compatibility.However members of Microsoft’s Xbox One preview program can take advantage of the feature now , and it will become available to everyone this holiday.
