Microsoft has confirmed that the company's Xbox Play Anywhere program is scheduled to launch on Sept. 13. It will allow games to buy a select number of Xbox One games and get the Windows 10 version for free, and vice-versa.
"The Windows 10 Anniversary Update and the related Xbox update coming this summer enable the Windows Store on Windows 10 and Xbox One to support Xbox Play Anywhere games," a Microsoft spokesperson told Polygon. "Then, beginning with the launch of ReCore this fall and continuing with Forza Horizon 3, Gears of War 4, Halo Wars 2 and others, when you digitally purchase a game that supports Xbox Play Anywhere, you have access to the game on both Xbox One and Windows 10 PCs for one price and your progress, game saves and achievements are shared seamlessly across both platforms."
ReCore will be the first official Xbox Play Anywhere game, which will be available on September 13. Microsoft already allowed people who pre-ordered Quantum Break on the Xbox One to get the Windows 10 version for free. In addition, the free-to-play fighting game Killer Instinct already allows players to purchase fighters and items on the Xbox One version and they are available on the Windows 10 port, and vice-versa.
While Xbox Live Anywhere does support cross-buy, along with saving progress, game saves and achievements, only some of those games support cross-platform multiplayer between the Xbox One and Windows 10 versions.
