Google has uploaded a new video to its YouTube channel that previews a game coming to Google+ called Play Your World with Google Maps.
There’s not a whole lot of info about the game that I can see, beyond its YouTube description, which says:
Coming soon, play your world like never before with a game from the Google Maps team on Google+ Games powered by WebGL.
At the end of the video, it says the game will come to Google+ in February.
It links to what appears to be essentially a help center, albeit an interactive one, for Google Maps itself.
