Purely by chance physicists have discovered a trans-dimensional matter that is called XM (exotic matter). For research purposes a new technology by the name of “Ingress” was developed. With the help of the app you have to collect as much XM as possible. You are challenged to occupy areas all over the world and to establish virtual portals, which have to be captured or defended. Portals are marked on Google Maps. You need to decide whether your want to belong the group of The Enlightened, which fights for XM and all it stands for, or if you want to be part of the group called The Resistance.
Naturally, the story is not real – however, you have to go to real places on the map to conquer virtual portals. The result is an augmented reality parallel world. To take part in the game you need a Google+ account that can be verified via a smartphone number, plus an active GPS location. To jointly conquer portals and establish strong units you may communicate and connect with other players via Facebook and Twitter.
