Maybe don’t buy Call of Duty: Infinite Warfare from the Windows 10 Store

Call of Duty players who purchase a PC copy of Call of Duty: Infinite Warfare and Call of Duty: Modern Warfare Remastered from the Windows Store on Windows 10 won’t be able to play with people on other platforms, like Steam, according to an update on Activision’s support website.

Infinite Warfare and Modern Warfare Remastered won’t support cross-platform play between Windows PC and Xbox One — the titles aren’t part of Microsoft’s Xbox Play Anywhere program. That’s not much of a surprise; the majority of Xbox Play Anywhere supported titles are developed or published by Microsoft.

More surprising, however, is the lack of cross-platform compatibility on PC. Buying the games for Windows 10 from the Windows Store will apparently restrict players from playing with PC gamers who purchase it elsewhere. From Activision’s support website, via NeoGAF:

Can I play Call of Duty: Infinite Warfare or Call of Duty: Modern Warfare Remastered for Windows 10 on Windows Store with my friends that are playing on another PC platform?

No, you can only play these titles with other users of Windows 10 on Windows Store.

If accurate, that restriction would apparently block players who purchase the game from Windows Store from playing with millions of people who have played the recent Modern Warfare and Black Ops games on Steam.

Call of Duty: Infinite Warfare is not currently listed for pre-order or sale on the Windows Store. The only title in the franchise currently available in Microsoft’s store on the eve of Infinite Warfare’s launch is free-to-play game Call of Duty: Heroes.
