Ingress is an augmented reality massive multiplayer online video game created by Google and released for Android and iOS devices.
Players of the game belong to one of two factions, “Enlightened” (the good guys, represented in green) and “Resistance” (the bad guys, represented in blue). The game-play allows players to enclose regions of territory on the surface of the earth with virtual links between virtual portals, which are visible in the game software. The top-level goal of the game is for one’s faction to control large numbers of “Mind Units”, the estimated number of humans within the regions of territory controlled by the faction.
The virtual portals can appear on any notable object and most have been created by users and submitted to Google for approval. In the Triangle area (Raleigh/Durham/Chapel Hill) there is at least 1,000 portals active with dozens more being added each week. One can “hack” these portals for in game supplies, regardless of which faction owns the portal. Claiming a portal is done by attaching an item called a Resonator and attacking a portal is done with an item called an XMP Burster.
