The even loster river

Since it’s at the bottom of the map and the area is so large, I imagine it was supposed to be for the single celled biome. Especially with how weird the sounds are

What makes this all even MORE interesting, isthat the prawn suit was ORIGINALLY meant to have a mark 3 depth module (that can still be accessed in the game's files)... imagine if the developers HAD left this "lost zone" in the game, and some player is just desperately trying to flee from one of the sea dragons, when they fall into a deep, deep hole, filled with nothing but darkness... and the sounds of something VERY, very new, lurking amongst the shadows, watching them.

That area was actually the sea dragon nesting zone, it was basically the lava lakes back in the betas where the PCF was meant to be entered from, while the lava lakes had a moonpool esque area like at the gun building, but they decided to scrap the area and just keep the lava lakes Source: memories of playing through 90% of the betas

We have the Lost River, now get ready for *_The Forgotten Cavern_*

"There's two spooky holes in the Lava zone that have weird noises and unused assets! Some people even made clips on these." "Woah cool! Can we see it?" "No."

Dude they need to talk about this when starting work on Subnautica 3. Who else is gonna try and get it on release?

I remember a long time ago while the terrain manipulator was in the game you could dig down overly far and find isolated caves that were otherwise inaccessible. Dont think any of them exist anymore, but it was cool.

Would explain the prawn suits depth

The only thing below 150 meters is sand, nightmares beyond your comprehension, and a mind fucking dark abyss

Idk why they didn’t just freecam under the map to look

Wild how you made this and didn't show the clips

The holes that are mentioned are probably the remanences of when there was a tunnel leading from the Aurora directly into the lava lakes as this tunnel was later sealed up in future builds.

Yes, you can also see this in below zero. Below zero is also technically the original game and they just diverged and started making unique assets for it. You are most likely seeing the bridge where they stopped developing one game and put those assets into the new game. A lot of creatures went through a few redesigns in early below zero development and no longer look like their first iteration such as the mantis lobsters.

Something cool you can do is if you place a scanner at the lava castle base and have all max range on it you can see some sort of big box outside the map that has nothing there, and it’s not the alien base. Try it for yourself

“Alright one last short before bed” *the short in question*

back in a day in aearly access I was playing a lot in subnautica, when they added active lava zone, there was for a short time TWO enters to the lava zone, 1 in lost river as it is now and 1 enterance was just next to the front of Aurora in the direction of the mountains biome

Recently I was fighting a sea dragon in my prawn suit and wasn't paying attention and started plummeting down this hole I had never noticed before. My prawn descended below the crush depth even with the max depth module. I jumped out and drowned while watching my prawn get crushed at what must have been below 1900m. Wasn't able to find where it was again

If you falling in the void(if for some reasion you want to do that) at a point if you open map in your seaglight you will see that the map show a biome was there. But there is not thing but the void. So ye, there is a cutted biome

Having pulled the game map from the files myself, I don’t believe so. I’ve never seen any evidence of an additional underground biome, but there is some remains of the old lava tunnel that found beneath the Aurora. If there were plans for something beneath the inactive lava zone, I’m betting it was just more lava zone. There are also a number of inconspicuous empty boxes floating underneath the map. A number of people have theorized that these were testing rooms, but I don’t think so. These out of bounds boxes happen to be placed relatively close to both locations where the lost river transitions to the inactive lava zone. This gives me two theories on what they are: 1. They are old attempts to sculpt the lava zone entrances, but these attempts went nowhere because the location of the entrances were moved. 2. They are just visual markers for where the triggers to load parts of the map should generally be placed. At least, that’s my theories. It doesn’t make sense for those boxes to be testing rooms. Typically you would put a testing room in a completely different Unity scene and as far as I know, Subnautica only has one, the scene it initializes in on launch.

I would be cool if it was a biome full of darkness with just one leviathan

I recall Markiplier playing it during Beta builds and just glitching down into an area with left over test stuff. This fricking T-posing player model stanfing on sand surrounded by total darkness remains one of the scariest things I have seen in games. It was so out of left field and sudden.

Fun fact: There are 3 unused biomes that were all of course scrapped but then later added to the sequel, below zero. The biomes are called Arctic, Lilypad Islands, and Twisty Bridges

I remember there being a biome in the early access game that was very deep i think, or maybe that was the early blood kelp zone that im remembering

This is a cut area, the Sea Dragon nesting area, which originally took the place of the Lava Zone. It was accesible from the surface, however it was blocked by the Aurora. I was unaware there was remains of it in the release however, figured it was fully deleted from the betas. There are multiple videos documenting it.

There was a terrifying big maw of a cavern entrance that was so big it looked like it would house a ginormous creature. It was past the butt of the ship toward the grand reef. It was in an early version of the game and it still freaks me out.

“Detecting leviathan class life forms in the region, are you sure whatever you’re doing is worth it?” Is something my pda told me right after a reaper leviathan attacked me

Remember the living biome...

As someone who has probably explored every square meter of this game's map, I can say with complete confidence that what you are talking about is an utter hoax. There are no holes in the floor of the ILZ. There WERE large areas of square, geometric terrain underneath the map at one point. These were basically underneath the whole map and required going into the void to access them. I assume they were a placeholder for a biome that was never added. They no longer exist however, last I checked. That is about the closest thing to what is mentioned here that I actually know existed at one point.

Glad to see this game still being played and adored.

When adventuring in the dead zone, at some point, my seaglide showed me a weird terrain on it’s map. Maybe it is the lost zone.

I've never had this nightmare, but I've had something...adjacent. I had a recurring fever dream as a kid. In the dream I had no body. Basically, my entire vision was filled with an unfathomable mass of white putty. The texture was almost exactly like Prestik. And somewhere in this malignant mass, a single thin, disgusting strand stuck out from the surface. It would already be pulling out of the putty, drawing some of the stuff along with it. The mass would sort of shift around sometimes, but the strand would never be pulled out, always limply straining against the hold of the mass. This putty, somehow, was my brain. I could feel it, the tension as the strand strained through it, and the sensation of the scene felt like a cold blade pressed onto the core of my brain. Or what I imagine pulling on my eyeballs would feel like. In the background, but also permeating the entire sensory experience, a muted droning/buzzing energy would complete the maddening sensation. Its intensity varied, but the whole scene as well as my brain droned along with it. It was inescapable, as real as the insane white mountain in front of me. Later I discovered that the sensation persisted somewhat even after waking up. It would mostly stop if I got up and walked around, but continue the moment I lay down and closed my eyes.

No, these areas do not have unused assets, and no there are zero unused sounds still in the game. Ive gone through every audio files, including ones that are not used and have found that the unused files are in fact unused.

Radiated biome?

Ngl 3 biomes that had to be added to subnautica would be the single cell biome , active lava Zone and a really deep biome in the void

I saw a guy go into the void and at a certain point he picked up a landmass on his radar I think somewhere around 4000 meters deep

The found river

Theres no hidden area, the "holes" area just empty areas of geometry from where the cross section cut through pillars

When using a max range 3d map in the map room while in the lava zone, you will find square-like shapes on the edges. They look like large rooms, but I could never glitch out to see.

It’s mysterious things like this that got me into subnautica, I wish I could use brain bleach to get rid of my memories of watching KZfaqrs play subnautica so I could experience it myself

is there anything that confirms this wasn't just something they ended up using in Below Zero?

Free guy in subnautica

Somthing like the cristal zone from subnatica below zero

A fact that if you go around 3000 meters deep in the void and use a seaglide map it will show terrain hinting that there could be a biome that was cancelled

Was fun back in the day using game engine tools to open Half life maps, and other game maps. You'd find locations devs stuck stuff, lost stuff, or just forgot it was there. Usually just a room at the edge of the map.

i remember this in the betas. it was some kind of nest or secret habitat for the sea emperor (presumably), which had an even deeper hole that just went straight down for a couple hundred meters and then stopped. markiplier actually has this documented in one of his old subnautica videos where he explored the area in the beta. it also has some other weird assets, like a copy of the players model on top of a rock in some corner. pretty spooky stuff.

i remember when the forest was still EA, i could glitch through walls in caves and i could circumvent parts of caves that way. the caves were so eery it felt like i found different caves every time lol

This reminded me of that hole you could find in the Below Zero early access. The map was fine and all but in one of the ravines or whatever there was a hole where they later put the Shadow Leviathan in I think, but before they did that it was a normal hole that led you UNDER the map, the depth would go on forever and would lead you to the dead zone I believe.

Oh hey, yeah I lost my entire save there because the PRAWN glitched inside. This was over 8 years ago

That would explain why the prawn has a 1700 meters of depth resistance at max when the max deepness is 1600 if stretched with the containment facility of the emperor.

I just started and I’m terrified to go into even the caves with the pink worm thingies. I keep chickening out once I make like 20 meters into it 😅

Back before the official release, before the lava zone existed, at the far end of the cave, there was a hole that was maybe a 100m deep. It was the lowest point of the map excluding the crater edge.

After thoroughly exploring the mentioned "holes" i can with 100% confidence, state that there is nothing there and that this is a hoax. Theyre not holes they are pillars/cave supports. I even went into ghost mode, theres nothing there at all

I like the idea that there are still some places unexplored on the map. I genuinely love when games can do that. I’ve played Skyrim a disgusting number of times and I still find things and places that I’ve never seen before. To think that such places and things could be in Subnautica is fun.

The deepest biomes in Subnautica were some of my favorite ones, especially the inactive lava zone/lava lakes. The thought of a place like that being underwater was so cool to me. I totally wouldn't have minded if there were several more biomes that just went deeper into the core of that planet. Even if it was nothing more than a pitch-black cavern (sort of like what the beta version of the inactive lava zone looked like), I'd be cool with that

So there's no extra biome and it was all a conspiracy theory

Oh that's just fred. Everyone say Hi to fred. He works hard.

This makes me excited for the sequel. I hope it's their biggest and best yet.

Years ago when I was playing subnautica for the first time, I believe 2018-19, I found a giant hole in the side wall of the ILZ. It led straight into the void. Afterwards I got an update to the game and never found it again… Some may think im lying but i am not. I definitly got straight into the void from the ILZ.

Sea Dragon Leviathan egg chambers maybe?

I can confirm the sighting of an unrecorded biome. In a creative world on below zero, I read the databank entry of a chelicerate. I thought it would be fun if I patrolled a peice of the sector too, or rather the entire thing. Way behind the half of sector zero that sticks out of the water, I found a strange biome filled with cubic terrain errors. One cube was shallow and made of sand, another towered above the water. They have various sizes. If you decide to go find it remember this was us below zero, and it took me hours to find my way back home so I recommend using a pc so you have console commands to speed things up. Also don’t use the console unless you don’t want below zero steam achievements, I learned the hard way that if you use the console in a creative file, you can’t earn achievements even if you switch to a genuine survival world.

How can this still be a "mystery" if people can use cheat commands to noclip to places?

In the early beta you could explore A LOT of areas like that. I followed a hole twice as deep as we can go in the live game. A lot was removed since then sadly.

Finally, the active lava zone

So, just stating for the record, subnautica's devs at multiple points used long straight tubes to go directly down into the caverns, before they finalized the entry transitions. It's been a long time since they existed, but there used to be a shortcut to I believe the lost river at the intersection of the safe shallows, the red grass biome with the seamoth bay in it, and one of the creepvine forests. There is this slope that you can walk down that often has a big drillable salt. Walking down the slope, the red grass is ahead of you, there is a large cliff above you to the right with creepvine on top, and the safe shallows are on your left. Along the wall leading up to the safe shallows, you'll find a large bowl shaped indent that has multiple little openings to shallows caves. Right in the bottom of that, there used to be a hole, and in older release versions, you can even use the seaglide's map or the scanner room to see a sealed inaccessible tube.

I remember accidentally clipping through the floor near the inactive lava zone and freaking out I was gonna lose it all (was using grappling in my prawn suit, Nintendo switch)

I remember there was a large cave like entrance near the front of the ship during the early access years which seemingly went down forever

Glad to see you using subnauticas best interactive map.

That would make sense, because I think in the game as released, the biggest depth upgrade is useless. So, it would make sense if a greater depth was planned at some point.

Imagine u fall down into it and its a entrance to a even more massive cave zone with something new modded or not. like a shadow leviathan or gargantuan. Man that would suck.

I wish I didn't look up where to go on my first play through, but at the time I had no idea where I was supposed to be going

Incroyable ! Un chat vs une armée de chiens, d'ours et tout ce que vous voulez et le chat gagne !

Obviously there is cut content in EVERY game

Yeah I love it when I’m travelling around and then get grabbed by a reaper my favourite activity

Nice time to bring up the cute ice biome

Remember when there was a hole around the Aurora, leading directly to the Lava zone?

The shadow glitch at the beginning😂😂😂

“Full of fantastical creatures” POV turns around sees a ghost leviathan

man i love this game i wish there was more normally dlcs are shorter so i was kinda upset there wasnt enough the game is so cool i hope they make a subnautica 2 with todays graphics and coding

Wiki: it's impossible to get down there Subnautica players: hold my beer

I was maxed out and had the deep travel upgrades for the mini sub thing and I would move so quickly that I could glitch through the terrain to get to the surface fast but my only deep diving vehicle got stuck in the map and now I can't dive deep to get the vital materials and am essentially soft locked now.

I remember finding a weird hole at the bottom of the Lava Lakes back in like early 2017. It led to an area that I think had default textures with a pit that led straight down to 1700 meters. It might just be something my brain just totally fabricated but it might have something to do with these holes

bro casually dropped forgotten lore after explaining what he liked about the game

For me, Subnautica was proof that procedural generated environments aren't comparable to carefully crafted environments. I'll take Subnautica's world over the endless No-Man's Sky and Starfield worlds.

warning, entering ecological dead zone, are you sure what you are doing is worth it?

“Players find something clearly displayed on map”

Hear me out, someone mod this back into the game and it’s just a massive dark cave where you can’t see anything, and have it house an adult gargantuan leviathan I imagine it being trapped down there and we just stumble across it

There is a console available in this game, you don't need to glitch through stuff, you can just use commands to teleport around

it was probably the area for the single cell biome

Anything before ice worm is not scary If you have a seatruck

Hopefully in sub 3 we get deeper bigger zones so I can justify using the Cyclopes more

There was a lot of unused asssets and biomes for subnatica that end up in below zero.

If you have watch DanTDM , you whould known that he found a modle of ryley robinson, maybe thats thevarea they were talking about?

There were a cut zone where like tentacles and stuff would reach out and grab your sub not sure if it made it to development but there was a concept art pic

man i played the shit out of this game back in the day i even remember the tool for the early access that let you dig in regular terrain (obv it got cut)

wow, soooo disturbing dude

i loved going deeper and deeper its just, below zero isntn as deep as the first i hope the 3rd one we get to go very deep underwater on the builders home world

If there's one thing I need in subnautica, is a map

Isn’t that about where the old tunnel mazes are from the beta version, back when terrain could be destroyed? I remember taking my cyclops into the tunnels by the aurora crash site

That's uhhhh... that's a nice square shade in your environment
