Nobody's quite sure if this is a real alternate reality game, a government recruiting effort, or something else entirely. It consists of dead drops around the world, strange phone numbers, obscure message desks, and encrypted messages to "agents" out in the world.
Join us in #ARG at irc.freenode.net as we try to decipher the purpose of this "game" together! If you're not interested in jumping into an IRC channel right away, take some time and read the wiki. It will give you a good background.
