It is July third, 1950. The Korean War is eight days old. National Security Council Report 68 is sitting on Harry Truman’s desk, a grim outline of the Cold War that is to enfold the world for the next 40 years. Alan Turing’s paper “Computing Machinery and Intelligence” is circulating for review. Cinderella is a box office sensation.

And you have invented a computer that can see the future.

Employing cutting-edge Ward-Takahashi identity derivations outside their quantum-theoretical framework, JUGGERNAUT processes enormous data sets, ostensibly in the service of code-breaking once the technology is proven and refined. The unstable geniuses behind the math have reached some curious conclusions that only experimental evidence can confirm. By the numbers, JUGGERNAUT —given enough resources— should be able to crack ciphers before they are even invented.

JUGGERNAUT is a live-action game about free will for 4-6 players and 1-2 hours that plays like a creepy Twilight Zone episode and requires almost no prep. Replay value is high and it is always weird and intense To play.

To play the game, you’ll need a private space and the soundtrack MP3, which simulates the ominous sounds of the machine. Labcoats and other props are optional!

“This game is brilliant, and very fun. Our game was intense and satisfying. My character ended up getting a lot of very personal predictions made … it’s a hard game to talk about without spoiling it, but it was very fun.” —Hans Messersmith

“We played an earlier draft and it was creepy, intense fun. The self-pacing job outputs really add an interesting dynamic, delivering information, bad news, and cryptic warnings in equal measure. Towards the end, we were afraid to draw them! This is one of my most favorite games, and certainly my favorite larp. There’s a lot of really smart things happening here, socially and design-wise.” —Caitlynn Belle

“It is a blast and very replayable. Get it!” —Eric Johnson
