Ok, things are getting out of hand and the joke’s already a bit spoiled, but if we’re going to be that serious, here’s the real twist — and the fun part was supposed to be how long it would take before anyone noticed…
Every archive from every silo will secretly stash, in its .txt file, all the data addresses from the previous day’s archives of every other silo.
In other words, the chances of a silo actually dying are microscopic. Even if there are holes in the silos, even if one is intact on a particular day, the data chain does not break. So either everyone survives or none survives.… meaning the game is basically unwinnable. Enjoy!
