Ingress is finally available to the public. Since its release it has required invites from friends; that restriction has now been lifted. It is good timing as Niantic recently announced a worldwide tour for devoted Ingress fans and players.
If you have been waiting patiently for an invite or just haven't checked it out yet, now is your chance. You will have to choose whether to join the Resistance or the Enlightened. Once you choose, get ready for an amazingly intense, fun and time consuming experience. Ingress has been quite the hit and removing the invite restriction will surely draw many more players in.
