It appears that Google might be in preparation to launch a gaming service, similar to Apple's Game Center.
The folks at Android Police who regularly feature APK tear downs of new Android apps, got their
hands on the backend for an extensive multiplayer gaming service while going through the contents of MyGlass, the Google Glass companion app, that was released recently.
According to the website, Google usually ships apps with a few Google-powered components that some apps depend on to work but Google accidentally shipped all of them, even though the service has no connection with Google Glass.
The underground Games service will feature support for real-time multiplayer games allowing users to play games with other connected players, as per the website. It would also apparently support turn-based multiplayer games such as board games where players take chances to play, and the teardown reveals that users will also get notifications when it's their turn.
Users would also be able to chat with other players within the game in real-time multiplayer mode, in addition to offering leader boards and allowing users to keep a track of achievements.
The game service will bring in the ability to invite friends and will come with a 'Lobbies' feature through which users will be able to chat before a game begins, plan strategies, rules, and choose teams.
The report clarifies that the app will just pass data between the user and a server where all the actual processing is expected to take place. It doesn't reveal an Interface as well since that might be dependent on the game developer or come with a new version of the Google Play Services app. It's name is also not known. However, it does point out that the service seems nearly finished so an announcement can be expected at Google's upcoming I/O event.
