Unknown Armies is: an occult-themed role playing game by John Tynes and Greg Stolze and published by Atlas Games, subtitled "A roleplaying game of power and consequences". Set in an underground society of mages, unnatural creatures and those who chose the red pill, Unknown Armies explores sympathetic magick in an unsympathetic world
The website, www.unknown-armies.com, is full of interesting creations by an active fan following. I have heard this game described as "Quentin Tarantino's Call Of Cthulhu" and it is a must for people who suspect that Deja Vu is a symptom of mind control and JFK was actually killed by a clockwork Jesus sent by the first Mother (and not with a bullet, but with a Ladyshave).
