Call of Duty: Infinite Warfare players that purchase the game from the Windows 10 app store will be cut off from the larger Call of Duty community. According to Activision's support website, multiplayer servers for those version of Infinite Warfare and Modern Warfare Remastered won't connect to outside services such as Steam.​

One of the questions listed on a FAQ page asks "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," the response reads.

This effectively cuts off Call of Duty: Infinite Warfare and Modern Warfare Remastered players that acquired the game from the Windows Store from a community that Activision has been cultivating since 2003. GameSpot has contacted Microsoft to find out whether there are any plans to lift this restriction.

Call of Duty: Infinite Warfare launches for PC, Xbox One, and PS4 today. In GameSpot's Call of Duty: Infinite Warfare review, Miguel Concepcion awarded the game an 8/10.

"By venturing beyond Earth--and not just to other planets, but to space itself--Call of Duty found a canvas to produce its best story in years," he said. It reinforces the notion that a game's narrative is only as good as its characters. Given the campaign's accomplishments in space combat, it's puzzling that no effort was made to replicate its zero-G sensations in Infinite Warfare's multiplayer.

"Consequently, the well-crafted Zombies mode is a more attractive, time-consuming proposition for those looking to play with friends. While no Call of Duty game has matched the comprehensive excellence of Call of Duty 4: Modern Warfare, the exploits of Reyes and Ethan are at least as memorable and moving as any deeds from “Soap” MacTavish and John Price during from the series' heyday."
