So, you know that strange area near the map when you go out of bounds? What exactly is it? If you noclip inside, it just blares an ominous sound that sounds like a broken alarm mixed with static or something.
Is it connected to anything? Is there any lore besides whats seen in the comic? Where did the audio even come from?
To me, the sound that blares could be the sound that blared back when the bunker still held astronauts and what not. The alarm either happened because some unknown creature native to Pluto's moon entered, one of the many pipes or machinery broke down and resulted in a complete melt down, or something else entirely. And due to how broken it sounded, it could have happened while the event was ongoing, which could explain why we don't see any corpses or what not; the alarm blared a little too late, and whatever happened in the bunker wiped out all living beings inside, but then what about the locked rooms? What about the bricked off and metal gates? They could lead to deeper parts of the bunker we haven't seen yet. The bricked off walls were probably rooms that were in the bunker for a long time, but due to something happening in said areas, it had to be bricked off. Not sure what could've happened in those rooms, but it sure was something. Then we have the rooms themselves which could give us info on what the astronauts did in the bunker, there's a library, elevators, a washing room, a kitchen, various bedrooms/cells, and oddly placed bathrooms. What I think is that the bunker could've been a place where astronauts lived and/or worked to gather resources from Pluto's moon and analyze them to send the information they gathered back to Earth. And the bunker is BIG so that only adds on more weight that this was some compound people either lived and/or worked in, but then I got stumped when I asked myself another question;
if this was a place where people lived, why is the entrance completely open and does not have a door? Surely there's no breathable oxygen on the moon, so how did they live, or WHAT lived there if it wasn't humans?
Now lets touch on the other noclip/secret areas, and even if a certain someone said it was beta content, they could still hold some valuable info. First there's the small room you can find by breaking a wall in one of the first rooms you can enter, nothing much is notable beside some stains, but to me it could be one of the rooms that was bricked/sealed off. It could be a room someone, or SOMETHING hid in. Next is the shut off shower room, again, not much is notable but it was shut off for a reason. Next is the area with the long vent and small upper level. This can tell us the bunker had various levels, which is a no duh cuz of the elevator. Next is the painting room found in one of the downstair room/cells, nothing besides a single painting, which honestly to me doesn't mean anything. And finally I'll touch on the area in the middle of the elevator shaft, which is by far the biggest secret area. It has various sealed off gates and rooms, and oddly enough every light source you try to put in said area doesn't work unless you get the key that's in the vent you can break open. Again, not much to go by besides there being more in the bunker, however, there is an office area that proves more of the bunker being a place of work. There's multiple sealed off doors, and one last door that's locked, and maybe in the future when the game updates, it can be unlocked with another key.
Another secret area is the one with the dented, sealed off wall, which can prove more of that someTHING entered the bunker instead of the melt down due to the wall being dented, and if you go beyond the wall, there's another door, meaning the wall could've sealed down just in time before the THING got there, which can explain the dents, and due to how close the area is to the normal one, the thing that caused the bunkers collapse could be nearby and hinted at more in future updates.
Then again, all of my rambling could be stupid, and this is just a cool, spoopy, map.
