Ingress is an augmented reality multiplayer online game created by Niantic Labs at first for Android devices and lately also for Apple’s iOS. The game has a science fiction back story and the gameplay consists of two opposing teams fighting between each other. Each team has to establish “portals” at landmarks, monuments, etc., and linking them to create virtual triangular fields over geographic areas. The interface of the game allows the player to see these portals. Progress in the game is measured by the number of “mind units”, people nominally controlled bye each faction. This number can be increased by creating more links or fields between portals.
