Microsoft's promise of unifying its disparate platforms with Windows 10 has even more going for it with some surprise announcements ahead of this week's Gamescom show in Germany. We knew that Xbox Live was coming to the desktop -- for free, even -- but that extends to HoloLens too. That's right: online multiplayer, friends lists and your achievements (anything tied to Redmond's gaming service, from the sounds of it) will be available on the augmented reality headset, according to VRFocus. The site also reports that HoloLens, Windows 10 and Xbox One will share a universal store for apps and the like "in time." Some purchases will also apparently be pay-once-play-anywhere affairs too. And similar to Microsoft's push to get Android and iOS developers to bring their apps to Windows 10, the ID@Xbox program will work to court indie game developers and extend across Redmond's latest operating system, HoloLens and Windows Phone.
