Google’s Niantic Labs on Monday announced that it was lifting the invitation-only restriction on its augmented reality game Ingress. The game launched in beta about a year ago, and interested players needed an invitation code to participate. Now all Android users can download the free massively multiplayer game from Google Play. The game will officially exit beta status on Dec. 14. In preparation for the launch, Niantic Labs has organized player events, dubbed “Operation #13MAGNUS,” in 39 cities around the world.
