@RedBackLoggd: That's correct; if I recall correctly, I encountered the first possible ending about 2-3 hours into my playthrough. Without delving into spoilers, I was given the opportunity to escape the colony in a sneaky fashion early on. Even though there were a few other loose narrative threads still hanging, I took my chances and got out of there. It was a welcome surprise to load my save and find that I could keep going. Glad I kept going as there's two additional possible endings that arise from that arc that were much more edifying.
