As expected, Google has brought Ingress, Google's near-real time augmented reality where you have to fractions trying to secure or take portals. Or something like that.
The game is now available for iOS users, as of this morning. You can install the app by going to this page. It has been available for Android users since November 15, 2012.
Here is a video from Google on promoting the iOS launch:
Ingress said on Google+:
Over the last year and a half we've seen many inspiring stories of friendship, exploration and adventure from the Ingress community including epic feats like flying into an Alaskan storm on a bush plane, scaling mountains, and coordinating operations across international borders, demonstrating solidarity and friendship, all through something that’s become more than ‘just a game’ for many of us. At Niantic Labs, we’re constantly amazed by these acts that demonstrate the power of community.
Today, we’re welcoming a new group of Agents into the community with the launch of Ingress for the iPhone & iPad: http://goo.gl/4bX9D5. Ingress is now a true cross-platform mobile experience, with Agents across the world playing together in the same shared, global game.
