The Subnautica Backrooms

[@MonikaCinnyRoll]

These backrooms are relic from when Subnautica was originally planned to have a procedurally generated world. The backrooms were at one point procedural but now they seem to be set in stone. Although, with having every single mod installed, I have encountered many oddities.

I remember discovering this exact spot back in the late 2016 early access build. The lava zone was still in development and it didn’t load properly and I ended up here. My curiosity got the best of me and soon triggered my anxiety. Considering it’s an empty space it’s incredibly tense and frankly horrific

[@Los_Alamos_Quadrobist]

Dang. I have heard about the glitch through the wall but never in any other Subnautica video I’ve come across have I seen the backrooms or the cube. This actually made the hairs on my neck stand up. Awesome video nevertheless.

[@Dimidibus]

I recently tried exploring the “back rooms” and I found that if you place a scanner room you can see some of the cube areas through the walls. Using this I found a large one and used console commands to get to it. The walls showed up on my sea glide hologram, but they where invisible and had no collision, though strangely they had out crops on it and there where a LOT of those random schools of fish you can’t interact with that are placed for ambiance.

[@mr.fn.brownstone]

This implies that normal Reefbacks have their own backrooms, which sort of make sense, because of how big their arteries and digestive tracks would be. So this actually.. Makes.. Sense?

[@thegappleknight3910]

I always glitch in the back rooms because I am a console player and at most I make a base there because it’s safe but it’s not when the other leviathans come with you

[@thereaperslayer9732]

im pretty sure i was exploring the lava zone in creative when i saw it. a wall... with a patch of almost pitch black stuff? i went through, and im pretty sure i ended up in what looked like the backrooms. im pretty sure after i saw what it was like and how dark it was i noped out of there before i lost the entrance.

[@thatrandomdood3625]

I've actually gotten here by going down into the void. I thought that my game was bugging out and it just wasn't rendering properly. It was one of the most terrifying things though as I couldn't find my way out and the background music scared me to death. Somehow though I realized I could make a base(This was in creative as I wanted to go down to the bottom of the void) and I made a fully functioning base with farms and bioreactor

Warper: *You're not supposed to be here.*

[@idk-ej3gt]

I were in backrooms and the reason of these biomes music, ambience and pda messages playing there is because its the bottom of the map and music that plays there is dependent on which biome is in top of it. So when in backrooms you have dunes music and ambience, you are under dunes. when you have bulb zone music and ambience you are under bulb zone. It is just a way how biomes work in this game they have limites x and z axis but not y. More interesting is fact that behind the front of aurora head, biomes ids are copied and in empty void (behing the void, there arent ghosts) you can still hear ambiences from e.g. bulbzone or dunes (not music and pda messages) maybe its bug but there are some videos on yt that shows strange sound in void (which is sound from bulb zone) but it isnt under the bulb zone it is in empty water with nothing ,behind the void behind the front of aurora head just with bulb zone id. Also water color changes in both backrooms and this place in void. Edit: That scary ambience from bulb zone is since 2014 early access so it is since 2 oldest version of game

[@shadowscythes]

I actually did explore these areas in creative a while ago, it's very strange and also unexpected cause I previously thought the bottom of the void was flat everywhere except the Lava Zone. Would be a really discreet base location though, I might try building in one of those areas sometime.

[@thegappleknight3910]

It’s a very safe place though probably because I am a console player it’s easy to glitch in just save and you got an entrance just make sure you don’t do it in a leviathan zone or any hostile area they can also glitch in with you

[@antmoundsock1122]

2:21 it has a one-way wall because of backface culling, where the game doesn't waste time rendering the back side of geometry that the player shouldn't see. As for why it exists, Subnautica uses dual contouring to polygonise a signed distance field that can represent the terrain, and uses an Octree for chunking. I suspect it was a mistake on a level designer's part where they accidentally cleared an octree node. I used to use the console to turn up the movement speed really high, and I've found at least two other cubic caverns like this that use the save shallows rock texture.

[@Jhoggie]

That's awesome appreciate the knowledge

I’m pretty sure this glitch is present in Below Zero as well. I used the teleport command to get to the Crystal Caverns and was instead transported to a bottomless pit with a wall. I thought it might be the void, but when looking up, I saw a ceiling. The wall texture looked the same as here too. Wonder why these box-backrooms exist?

I know the awnser, the devs of the terrain of the game first create cubes where the map will be inside, there are none of those cubes or "walls" where there wont be any part of the map. That is why you are able to reach the void walls at the bottom and there isnt anything under those cubes. Please Reply to my comment if im wrong

[@JewelyPop_]

I found this by accident once, but not by going through the lava zone. I was messing around in creative and went to the void around the south-eastern section of the crater, and started going down. Eventually, I found that the void just.... stopped. and started moving inwards. I was terrified, rightfully so, so i constructed a scanner room to see if the wall just hadnt loaded (I was playing on xbox at the time, it was VERY slow.) even scarier still, the scanner room was trying to tell me that the wall... was still THERE. I pondered about this for a bit, even swimming under it a little, spawning a cyclops even. I didn't dare go further inside than what I did. I had no idea that I found the exit to the backrooms.

[@ronanmachin6914]

Try disabling quarantine enforcement platform whilst the sunbeam animation is happening and see if it lands. In the animation it arrives and gets shot, just disable is when it is attempting to land but hasn’t been shot yet

Maybe it was supposed to be a another biome, but it got removed, or they didnt have enough time, or they didnt have the budget, or something else

I think they might be to decrease the amount of terrain that loads.

I think that the weird ups and downs are similar to Chunks in Minecraft, the devs edited base blocks of terrain to create the Subnautica world we play in

[@Reir0o]

That "maze" was built like that because it made it easier to build the actual playing zones, thats it lol. The developers didnt bother making a bugged zone where you would just die. It's too much work and waste of money.

[@terratherat]

Funny story, I once traveled from underneath the map in the Dunes Biome all the way to the cube beneath the lava zone that's being discussed here. :) It was in creative mode, but all I really had was an upgraded prawn suit. That's all you really need to hang out in the Subnautica Backrooms lol

[@adrianaguilera8701]

getting teleported would make sense as for there is only one person in the backrooms that made it out and found the exit now on each floor it has a astronomically small chance to spawn in for you and even if it does it teleports you somewhere random on the world

[@sillygoofygoober74]

Holy hell...... the other day i found this box under the map while exploring with my cyclops..... i thought it was unique. Looks like its actually directly under the lava zone. I had no idea.

[@lukesaylor6742]

Just so everyone knows, you can safely get down here with a cyclops using sonar. You'll wanna carry ALOT of ion power cells. I carried like 2 full sets plus the power upgrade. It'll last you a good while. At certain points the walls do actually go deeper than the safe crush depth. I'm planning a voyage down with even more power cells and I'll use the shield generator to go deeper. Running both the shield and the sonar at the same time will eat my battery so quick so I'm gonna need probably a few full lockers of ion power cells. Also the part where he mentioned a flat place for a base is another spot I found. It's this ledge thing. Only walls on 2 sides and the rest is open water. Interesting shit.

One time, awhile ago, in an earlier version of the game, I was walking on the area above the Quarantine Enforcement Platform (the really big gun; not actually on the gun but on the part of the building where the roof and the island meet.) Only some part of the building didn’t load properly, and I fell through the building and wound up in a little land-locked dungeon underneath the building, and couldn’t get out. Most of it was under water, but there was one tiny crevice I could go to to catch my breath. But at this point, I was panicking, because I hadn’t saved in hours. I was prevented from going back to the proper side by invisible or land walls all around me. Right when I was about to give up, and was going to cry, a Warper who was very close to the building sensed my presence and came flying over. I have never been so grateful to be attacked before! He threw a portal at the wall, and it touched me and teleported me back to his side. Of course, I had to swim away fast, or he would’ve killed me, but man! He has no idea how helpful he was to me.
