Ingress is a game/app for Android and iOS devices. It is technically an AUGMENTED REALITY MASSIVELY MULTIPLAYER ONLINE ROLE PLAYING LOCATION-BASED game (which is a real mouthful!)
Developed by Niantic Labs, a start-up within Google, it uses Google Maps as the basis of the game. It has a big, multi-layered plot that has been developing over the last few years.
The gameplay consists of establishing “portals” at places of cultural significance, such as public art, landmarks, monuments, etc., and linking them to create virtual triangular “control fields” over geographical areas. Progress in the game is measured by the number of “mind units” (MUs) captured via such control fields, i.e. people nominally controlled by each faction (as illustrated on the Intel Map).
The necessary links between portals may range from yards to miles or even hundreds of miles and teams of people across the entire world work together to complete control fields (for their side) or to block or disrupt control fields belonging to the opposing team.
Events take place where hundreds of players will gather together, representing both teams, and these are often tied in with charitable events or other sponsored activities. There is a definite community that has been built up around this game, which is taking place “invisibly” around us at all times.
