there's 3 endings for different route choices in fracture events: "Void" for rejecting the fracture and ignoring it, "Contact" for communicating with it, and "host" for trying to control it, plus what I assume is a 4th ending after you get all 3.
Void is still the hardest of them all to get, because you basically need to get the starter 0.1(1) paranoia production then DO NOT buy ANYTHING that increases paranoia production until you get the next fracture event, then start buying all the paranoia draining upgrades you can to put the production into the negatives.

Sorry for the late reply! I've been busy working on another project. You're right, the Fracture endings were pretty tricky to get, especially Void. I actually just released an update reworking the whole Fracture system, with more player control and clearer choices. Thanks for taking the time to dig into the game and figure all this out!
