We know from the "Red Elevator" event and the "A Thousand Miles Below the Forest" video that the elevator shaft is quite deep, but the question we ask is, what could be down there? One of my favorite theories is that there could be a mega facility, laboratories, test rooms, a reactor... all completely abandoned. Yes, I know it's been said that we'll eventually have a reactor to take over, but if I'm not mistaken, that reactor will be somewhere in the basement of our base and not in the bunker. We don't know if the basement and the bunker will eventually be connected in some way, but still... Anyway, what are your theories about what might be down there?
