Control Fields are what Ingress is all about. It is the vehicle that drives the control of mind units for the two factions you are given as option to play in the game: Resistance or Enlightened.
It’s a classic battle of good VS evil, who will win? Well, its not that clear cut and easy, it is a strategic chess game that appears to never end. Tonight we received a juicy bit of information from a @IngressLondonSE claiming that London, England is the home of the largest control field in the game/world. Can this be true?
