What Will Subnautica 3's Biomes Look Like?

One of the most impressive aspects of both Subnautica and Subnautica: Below Zero are their beautiful and expansive underwater worlds. Despite this, it's likely that after two Subnautica games, the developers are running out of alien underwater biome ideas for their upcoming Subnautica 3 game. This is where I come in. With some inspiration from the community, I've created four unique biome ideas that I would love to see in Subnautica 3...
This project has taken me many months to create. The goal in mind was to create one of the best videos I have ever made for this channel. So I really hope you enjoy :)

Hey y'all! I have a great idea for a 100K subscriber special, which I will (hopefully) be posting soon. In that video, I will also talk about some important updates concerning the future of the channel. Anyways, I hope you enjoy this video!! :)

[@user-ij8pn7mw1h]

[@threehades9967]

I would kinda like to see a place in the next Subnautica game which would be called a Blood reef, in which there is many plants and fauna that of which is generally red given the name, everything would look jagged and dangerous to mess with but then you eventually learn that all of the creatures are actually just scavengers and are just docile in nature. Also would like to see more prawnsuit tools like a prawnsuit scanner arm, repair arm, and vacuum arm. Those arms would serve as a more efficient way to use the prawnsuit while deep in hot water or dense water, or even acidic water. Then there is the next ideal biome for a Subnautica 3, an acidic pool biome. It would be a place only accessible with a prawnsuit that of which has an acid resistant coating to allow it to traverse through potentially dangerous acid if you don’t have the coating. This pool will contain little to no fauna and plants besides a couple small scavengers that rely on the acid to shelter them from predators that can’t touch the acid. The resources around these parts would consist of sulfur and lead which is what’s causing the water to be acidic. Those are just a few ideas that might serve well if implemented. I’m hoping that Subnautica 3 will be just as good as the original Subnautica, but much bigger than Subnautica below Zero, to me Below Zero was just too small and lacked all of the proper design to make it pop out.

[@Yuh699]

@@threehades9967 I ain’t reading all that💀

[@Nadiki]

Below Zero’s Lilypads are peak honestly, they really nailed those. It’s a beautiful and unique biome that’s backed by a real life phenomenon and on top of that it has one of the best music tracks in the whole game. My favorite of your conceptual biomes are the Magnetic Fields and Emerald Grove because they too are grounded in real world phenomena and then taken to the next level. Earth is covered in magnetic anomalies that geologists suspect are caused either by unusually high concentrations of magnetic minerals in the crust or by clumps of magnetic material deep in the core. Sometimes in those places aurora can be seen, which I think would be really cool to have above the Magnetic Fields. I also think it could be a much more pretty biome, with banded blue, black, and red stone thanks to the high concentration of iron and cobalt minerals in the area. It would reference how we label magnet poles and also an Earth phenomenon, the banded iron formations, in which the entire ocean essentially rusted (several times) and then was deposited onto the seafloor which eventually made its way into the geological record. Maybe something similar happened on 4546B in its distant geological past, hence the uniquely high concentration of these metal oxides. This formation would be either exposed by erosion or uplifted by geological activity. The flora and fauna in the area would also reflect the high levels of metal in the area, incorporating it into their biology for hard shells and vibrant colors that are otherwise extremely rare in nature. I think vehicles and navigation systems being disabled by this area is a very cool idea that would force the player to think differently, but disabling all their tools entirely might be going a bit far. At least making an upgrade or module to their tools rather than requiring a whole new set would be nice The Emerald Isle is a representation of breathable sea caves, which are a real phenomenon that are seldom seen because of how extremely dangerous cave diving is. If included deep within what is essentially the cave diver simulator biome, this could be a fantastic treasure of a biome for the player to find. It should be so deep within the caves in fact, and blocked by caves just thin enough to prevent vehicles besides the Seaglide from going through, that you will either need multiple air tanks or the best air tank and the knowledge to follow the crystals in order to reach it. It could have multiple entrances too rather than just one due to the air pressure keeping the water out. A unique oasis that can only be found by the brave, witty, and prepared.

it could start in a cave slowly going up to the surface extremely hostile and always trying to kill you, different from other creatures that are territorial, those want specifically to kill you, so instead of being capable of ignoring like most creatures, just seeing the player makes it target them until they die

Better idea rotliothan ( rot leviathan)

[@gachaofthegalaxy915]

That's what I was thinking

[@therealspeedwagon1451]

What I was about to say. Maybe the Rotnest could be the final boss in a way for Subnautica 3. Perhaps as the game progresses the Rotnest spreads outward and corrupts the other biomes. Perhaps there could be a Frankenstein leviathan at it’s center made up of the amalgamated corpses of other leviathans and that could be the central brain of the gestalt consciousness. Sort of like a grave mind. Killing such a leviathan will eventually result in the complete destruction of the Rotnest.

[@CreeperPlaysGames373]

Makes me want an underwater halo mission

[@OneOddKitteh]

I get why people were disappointed with how barren parts of the below zero landscape were, but I also feel like the devs did a pretty good job of working with the likely limitations of an Arctic landscape - yes there are large spots of barren water, but the eye jelly blooms are truly stunning. I feel like it really did capture the idea of being super close to a planets magnetic pole, yknow? Less colourful and full of life, but still interesting. Your ideas for potential biomes for 3 are absolutely stunning, though! I'd love to play in any of these, and I hope the devs take note.

[@SuperSecretAgentNein]

I actually loved Below Zero, I think in part because I took people’s advice and waited a while after the first game to play it.

[@rasberryiceify]

The game never felt barren to me. Even in the emptier areas there were holes to explore and creatures to see.

Idea for the rotness: When you interact with it the signal travels trough the nerves so that it takes some time to respond, this could make for mechanics like the rotness surrounding a mineral deposit and you have to grab the mineral and escape before the signal reaches the "brain" and back.

I like the idea of a tropical biome. Something like a far larger version of the islands in the original Subnautica. Perhaps these islands could also have Chinese potatoes that simply took root when the Aurora fell.

[@brodriguez11000]

An underwater Amazon forest.

[@Infity0]

The Rottnest would be so cool if it worked terraria’s evil biome and at the end of the game you have the option to make something that can kill the Rottnest and after you restore the old biome you get a endgame reward like a upgraded prawn suit. It would make the biome so much better if the biome grew bigger the longer you play the game adding this mechanic to the game would encourage the players that are scared of the leviathans to progress farther into the game to stop the Rottnest from taking over the entire map. There is a few more things that would make this even better. Letting the biome grow to your base will cause your base to be destroyed until you push back the Rottnest. The rottnest could be the mutated bacteria from the first game and if it was the mutated bacteria it could be apart of the story.

[@SpeedyMouse]

Yeah, that's actually a phenomenal idea, I love Terraria so having a similar mechanic to the Crimson/Corruption would be amazing!

[@SpeedyMouse]

Yeah, having a massive current spanning throughout a large chunk of the world would be really cool, I'd also imagine it would help to some extent with transportation around the map.

[@skittleman5630]

id love like an elephants graveyard type biome for leviathans similar to ancient river with the skeletons but with significantly more skeletons of a wide range of types of leviathans and the unique creatures would be adapted for camouflage there amongst the bones

That would definitely be really cool to see, yeah. Maybe after the Rotnest was killed, its biome would turn into that kind of thing.

Damn speedy, haven’t seen your account in a good few years. I remember you once gave me advice on how to get over my fear of the Aurora in the first game. Nice to see you’re still at it with Subnautica. Especially with the third game coming out soon

[@esperity]

Suggestion to Emerald Isle: Sunlight being transferred through the crystals. Maybe there is a giant crystal on land and the light can get through lighting up the emerald isle. That could explain why the plants use photosynthesis like the plants you showed. And because of the extreme isolation the plants and possibly animals living there could be unique to the emerald isle!

[@Viper76PL]

I quite like the first two concepts, but I gotta say I am IN LOVE with the concept of the Magnetic fields, what a unique enviroment! disabling your vehicles and tools could be such an insanely diffrent challenge, not to mention the very appearence of the biome being so diffrent to any other existing biome.

[@Osniax]

An idea for the catacombs is to have something like the spy penguin from subnautica BZ so you can go through the small tunnels and see what is behind but has high energy usage and like 16 storage slots. And if you loose all power in it you have to pick it up again. It would also be kind of hard to get alswell so maybe 3 fragments to unlock it and something like advanced cable kit (idk what it is called) a titanum ingot, magnetite x2, lead x2, nickel x4, kyanite x2 and a powercell. But i am very unsure of this idea, it may be to overpowered because you dont have to go into the caves but to balance it out maybe let it have a like 150 meter range until you loose connection and have to get closer but if you cant you have to go pick it up. And make it have like a maximum 50 temprature before it starts to break. And crush depth maybe like 400 meters and only has 1 slot for upgrades, 2 depth modules and its max with upgrades is 1000 meters, maybe a speed upgrade and a sonar or something Maybe a bit overpowered but would be fun to have in game Love your content, dont stop!

[@SpeedyMouse]

Yeah, I really like that idea, having some sort of miniature submersible/probe type thing would be really cool!

[@user-gw1dn1bj7t]

[@matthewanderson7824]

I hope they add some rain world mechanics like procedural animation or extremely unique behaviors like blindness, solely targeting the player, telekinesis which could result in cornering the player, deaf, or two species organically working together. Even with the unique attack patterns and behaviors of creatures in Subnautica one their detections and reactions are still pretty simple. Creatures with different viewing distance, or biomes with more or less visibility affecting AI. Or even different types of light, some biomes are more opaque in certain wave lengths, possible predator like creature that sees in IR translucent water

[@SpeedyMouse]

I agree, those are some great ideas.

[@matthewanderson7824]

@@SpeedyMouse the telekinesis and biome visibility would work well in your Rotnest biome

[@admiralassblaster6320]

The Rotnest as you describe it is an insanely good idea. Sounds like it would have the typical amazing atmospheric qualities of any other Subnautica biome but with the added tension, and gameplay variety of forcing the player to traverse stealthily and avoid detection. It’s almost like the biome itself is one big leviathan that you can’t simply run from like the rest, so you need to hide from it. Love it

[@scarletgamingstudio]

Rotnest having a corrupted spider web theme would be extremely suitable for a species idea. Under water spiders for me personally would be an absolute nightmare so having a side quest to stop the rotnest would be one hell of an adventure. And I think having under water spiders as the main entries of rotnest that infect other creatures and give them semi similar traits while also keeping some specialist traits. As for the underwater cavern idea I’d say having the caverns echo would be even more terrifying and maybe give a chance for reaper leviathans to be introduced. Granted I think they would have to be a bigger areas giving the smaller hideaways a 50/50 chance on if it’s a safe spot to hide or not. Magnetic Fields would be perfect for not only electric based creatures but could be connected to lava based areas nearby. Having rubber suits would be a nice combat against the electrical shock, and I think maybe just maybe rotnest would have a special use if it becomes not just a cure but also a utility. Much like how webs can be spun into threads and string let alone cotton I think giving rotnest a rubber-ish concept would be perfect and would add on importances to the rotnest side quest. That being said the magnetic fields would be perfect for more crab, lobster, eel, and slugs. Oh maybe even having an abandoned ancient mine from the aliens before the Kara Virus got out. The Emerald Isle would also be perfect for introducing bird, lizard, and even some cat or dog based creatures maybe even dinosaur-ish creatures if the caves were to be big enough. Maybe wild pig-ish creatures too. I hope these help expand the ideas you have and honestly I agree with these concepts could be deemed very very useful

[@johnjoe69]

Bro you have changed so much. I remember your old Subnautica vid helping alot. You were just a kid but already made good quality informative vids even then. Keep it up bro, hope you become a bigger youtuber.

[@Lord_Promin]

I actually have some ideas for the bioms... The Bony fields (the title can be changed) is a biom where there are many bones of different creatures left by a creepy predator that lives there. There is one peculiarity and a serious drawback in his digestive system: the bones of the creatures he ate remain intact for a very long time, which is why there are so many bones here. No fish can be found there because of these bones around (they just turn around when they see it). Because of this fact they didn't have enough food and began to become extinct. Some died of starvation, others... found food from their friends... That's why there is only one predator left, the strongest one. In this biom can also be found the remains of other representatives of this predator species died by _some_ causes that can be scanned and the information can be uploaded to PDA. The predator is starving and he's very aggressive to any living thing swimming into his territory. This predator may have many wound on its body left by his _friends_ he ate. The other one is The Impassable Treecaves (the title can be changed), a cave system made by many lines of vegetation (I just thought: it can be surface biom with the same mechanics as I mentioned above and below). The main feature of the biom is in countless number of plant lines making it imposible to move around in any vehicle and nearly impassable to move by yourself. Its countless number also makes impossible to navigate there (it's like roots in the mangrove forest: almost inpenetratable for an eye). The colour palette of this place can be from green to red (as you wish by the way, I don't know the exact colour: just as uncomfortable as you can imagine of this place). In these caves there are many forks with narrow tunnels. It can be mini biom for The Rotnest or just an independent biom leading to somewhere (or something). If it's a Rotnest biom it can have some paths that can close and open in an unknown sequence. And also the tunnels can become more narrow and even hang down some deadly plants (like hanging stingers from Subnautica 1 but something else). If it's just a biom, separate from Rotnest it can also have some features but I didn't think about it, you can think about it. Tell me if you liked my ideas or if you have something to add. I would like to listen)

[@norielgames4765]

[@mossballl]

Very cool ideas, and I'm so glad you commissoned artists to draw the ideas instead of using AI

[@sharondornhoff7563]

I like the expansion of the original rotnest concept to a complete biome/story challenge in its own right. Perhaps the colony was spawned from the surviving crew or living cargo of an alien vessel, neither human nor Architect, that was shot down by the Enforcement Platform centuries ago? Think John Carpenter's The Thing crossed with a cordyceps fungus. The colony's core might encase the vessel's weird wreckage, which the player needs to scavenge to achieve some larger plot-essential goal. A discovery like that would be a nice chance to build up the diversity of sentient life in the wider Subnautica universe, beyond the glimpses we got from datapads and the Architects' museum exhibits.

[@SpeedyMouse]

Oh yeah that's actually a great idea, I really like that.

[@Luv-sic-]

i dunno i found it wayyyy too deep and nerdy lmao

[@alicejests5431]

I've always loved coming up with biome/creature concepts for future Subnautica games, and so here's a few of my own. 1. Night Garden Grove This biome is very much inspired by the Lilypads biome in SubBZ as it would be completely covered in plant life. The seabed would be covered in tall seagrass with patches of bioluminescent flowers. The biome would contain structures/ships from either Alterra, the Architects, or some other unknown race that would have collapsed to the seafloor and be overtaken by the surrounding flora. Some of the creatures I thought of for this biome were something like an underwater firefly that glows a bright orange light and wisps around the open sea above the ground. The other one was the Ruin Walker Leviathan, a giant leviathan around the size of the Reefback with a similar design to the Sea Treaders, it would be completely passive and wander around the ruins feeding off of the seagrass. 2. Crimson Reef I really like the idea of a biome themed after crimson and carmine, and so this biome would be filled with strikingly red coral, plants, fungi, and creatures. The biome would be covered in vein-like roots that make their way down into some kind of drop-off or trench within it leading down to the Deep Crimson Reef, where the roots would connect to a much larger crimson hivemind-like plant. The biome could contain fauna like the Carmine Crawler, a Rock Puncher inspired creature with a scorpion-esque design that would feed off the coral and roots, giving it its color. Another creature for the Deep Crimson Reef could be the Octobrooder, a large octopus-like creature inspired by the Crabsquid with eight curling tentacles, piercing red eyes, and a hostile attitude to those who venture down into the crimson depths below. 3. Mangrove Aisle We haven't really had any mangrove-like biomes yet, and it would be cool to see one in game. I like the idea of a tropical biome with towering mangrove trees that sprout up above the water and shoot down all the way to the seafloor, spreading their roots out at the bottom. I don't have as many ideas for this one but maybe some piranha-like creatures or even anaconda ones, anything that fits the tropical rainforest/amazon vibe.

Crazy to actually see the finished video after so long

[@SpeedyMouse]

Yeah it's great to finally get it out. Thanks so much for all the help!

[@ThatGuyStu]

Those we're the best ideas I've seen in a while lol, I hope unknown worlds actually listens.

[@func_e]

bro played halo 3 and was like "imma need to see that in subnautica"

[@Guess-who-board-game90s]

Bro I haven’t watched you for years and got jump scared by your voice probably going to start watching you again because I’m starting to get back into subnautica

[@rfactor1502]

Something I'd love to see is something based off the Sargasso Sea in the Atlantic, a spot that has an ocean gyre that causes for a lot of surface plants. You could even dive into the more fantastic ideas of it and have patches of this seaweed (IRL actually a form of algae) being actual walkable terrain. This would likely result in a biome that has strong surface and depths, with stuff like stranded equipment or usable plants being on the heavy walkable patches, and the depths possibly having tangles of kelp in areas not shadowed by large Sargassum tangles and clear rock where there is not. Or it could be over a particularly deep area, such that the depths more closely resemble some of the stranger low light plant and coral life we see in deeper parts of Subnautica. This could even be a possible starting point for the player, having had an ocean going vessel become too damaged to be used as anything more than basic shelter, stranded in one of the tangles of Sargassum. Some shallow just below the surface areas are nearby, giving those needed early resources... but the deep depths nearby are potentially dangerous, possibly with leviathans that do not approach the surface, but are always ready for a meal that comes down to them.

bro i had like a subnautica phase a couple of years ago and used to watch your content alot, i got recommended this video and holy shit your voice has changed😭 it was like a jumpscare not hearing your voice from 3 years ago, but ig i shouldve expected it💀

[@gavenmace7779]

I love the catacombs Idea, I mean imagine a massive snake like leviathan that makes the deep and winding tunnels its home. I can just imagine the horror factors they could do with that. You can see glimpses of its bright eyes through a tiny hole just watching you, or its snake body slithering away when you shine a light at it down winding deep tunnels. The Rotnest it a cool idea aswell, could make like a grotesque organic rainforest and cavern systems, with the 'plant' life actively trying to infect you the deeper you travel into the massive organism, like those mushrooms that grow for miles under the ground

[@utfofuo4468]

Another beatiful edit

[@strayphilosopher4795]

I feel like a biome that is inside on of the mobs’ body would be super cool. Like an unknowingly beautiful oasis inside a semi-dangerous leviathan that can only be accessed if it opens its mouth.

[@kingnocho1231]

reminds me of the stellar basin from dredge

[@theaceofhearts9131]

Man your voice has changed since I watched you last. Awesome too see your still going since then

[@Sisco748]

I wanna see at least one of these in Subnautica 3! So good ideas!

[@LeShawnDeWalrus]

9 minutes in and i just wanna say: Rotnest sounds like a place i would do everything to avoid, so i think its perfect, it would also need to look the part, like yellow murky water and the core being pretty claustrophobic to get to.

[@hellohi2516]

For the magnetic fields, I think a cool feature would be rocks that float in arcs along magnetic field lines, like when you put iron filings near a magnet. These rocks could be disrupted by creatures or changing magnetic fields, but then reform. If the intent of the area is to be more chaotic, then perhaps as a one-off landmark, there could be one massive magnet with huge rocks forming rings around it. The upgrades for your tools and vehicles could also make the area beneficial to explore by allowing you to charge them by traversing the changing magnetic fields. That, or have a base piece that can provide power based on the local magnetic flux.

[@nitzan3782]

10:30 Additionally, the Rotnest might have been dormant to withstand the Kharaa, and with Enzyme 42 spreading across 4546B, it has now reawoken and poses a threat once more. Perhaps even repurposing the Architect ruins.

[@SergeantRedacted]

Bro i remember when you only had 30k time flys by so fast wish i could relive the good old days i used to stay up late every night wathing your vids

[@Ozeglion]

All of these ideas are fantastic, especially the Emerald Isle and the Rotnest. I actually have a couple ideas for the latter: Maybe the origin of the rotnest parasite could be a species of microscopic organism native to the planet that had been somehow mutated by the Kharaa bacterium, and the reward for destroying the rotnest organism could be that some of the dead rotnest matter ends up crystalizing, and, after an amount of time, turning into valuable minerals for the player to collect (this would be a reference to one of the concept art pieces for it that were originally made for Below Zero)

[@knuckleheadwestwind3585]

I think that the rotnest has more to offer than a zone. If you’ve ever played Hollow Knight, that game has an Orange infection that, halfway through the game, overhauls the first area into an extremely dangerous one. If you’ve played Sekiro, that game remixes its early areas after an invasion force arrives, making it more difficult. If you’ve played Metroid Dread, releasing the X parasite affects the entire map. A rot infection that comes out in the endgame could make an incredible conclusion. For instance, you may go all the way to the bottom of the map, but have to make it back to the top, but this time the world is infected. It could be a serious innovation that sets the third game apart from Subnautica 1.

[@erickck240]

Honestly i would love to see an electricity biome that you would need to go to, to get electricity to make new machines.

[@AHandleWasAlreadyTaken]

I see 3 possibility’s for subnautica 3. it being set in an eruption or opened volcano type area, being in the void, and being something I didn’t think of

[@therealspeedwagon1451]

I really like the idea of the Rotlands. It reminds me a lot of the Flood from Halo. Perhaps the Rotlands could be like the final boss biome in a way. Where it has the best loot and the most dangerous mobs. Perhaps there could be a Frankenstein leviathan at it’s center that acts like the central brain of the entire collective consciousness sort of like a grave mind. Perhaps the player will have to kill this central brain to destroy the Rotlands once and for all and in it’s place a permanent scar is left on the world; a biome of decay and death that although inert is still very dangerous and should be avoided at all costs as all the great loot would be gone with the Rotlands.

[@KaiTheMemeKing]

I really hope they implement the magnetic fields concept. Forcing the player to free-dive is a super cool concept that would remove a lot of safety nets people take advantage of. This biome should definitely be mandatory to pass through to beat the game. I think the biome should definitely air on the side of "unique tools/vehicles to explore" rather than vehicle upgrades. I would much rather players experience the magnetic fields with a seaglide than a prawn suit

[@futuristicbus61]

Dude I love speculating and crafting concepts for areas and features in games like Subnautica. I’m so freaking excited for the third game! I honestly can’t believe that a silly frightening water game has become okie of my absolute favourite games 😊

[@Mark-wr8td]

rotnest looks super cool, lets hope it gets added to the game

[@jonmann4980]

Damn bros voice has gotten deep since his video showing us where the cuddle fish are. Thanks for the help great video

[@electrominded8372]

An idea: A biome called the Hole. This biome features a seemingly endless downward tunnel, huge and almost circular in scope, that tilts ever so slightly in an ascending arc that eventually forms a 'U'. This tunnel descends at least 1200 meters and the player will pass through different layers of sediment, organisms and minerals on the way down. On the way up, the biome ends inside a megalithic dome of some sort belonging to another biome. Thus, the only way to enter the next biome is through the Hole.

[@ThommyofThenn]

The deep lillypad caves captured that sublime exploration feeling but even a great biome like that still struggled when compared to the first game. I'm ok with the storyline stuff that BZ developed but I can also see the next game starting anew! And like another comment mentioned, the fans have come up with some very cool ideas for biomes, broader settings, and story ideas. I totally agree there is a ton of collaborative potential here!

[@hellohi2516]

Back when the first Subnautica was still in development, when rumors about the Sea Treader were first surfacing, I had some crazy ideas about what it was going to be. When I first heard it was a giant crab creature, I was thinking absolutely massive, like giant claws reaching out of the dark abyss to grab your cyclops. Then, when I heard that it would be called the Sea Treader and inhabit a biome called the Sea Treader’s path, I thought it would be a predator prowling a central path and you would have to hide as it passed by in order to traverse the path. Needless to say, I was a bit disappointed that the Sea Treader Leviathan wasn’t really a threat, but those first ideas inspired some ideas for biomes that are defined by their megafauna. My first idea of claws reaching out from the depths turned into a stationary creature sitting in a very deep section of the map, waiting to grab things that swam above. My idea for a biome would be creatures similar to the Spikey Traps in Below Zero, but more crab-like and quite a bit bigger. They would live at the bottom of self-dug pits, like antlions. They wait for prey to come close, then reach out and snatch them, pulling them to a central mouth. The biome would be defined by a series of pits. Some would have tentacles/claws reaching out, lazily waiting for dumb prey to swim near them. Others would have their arms retracted, waiting until the prey dives down into the pit to ambush them. Most would be just big enough to grab your person, with a few being big enough able to grab your personal vehicle as well. At the center of the biome, there would be a massive pit, so deep that you can’t see the bottom from the edge. You might not even realize it’s a pit until you explore deeper, drawn by valuable resources, until the ground begins to shake and massive arms surface from the sand as a maw opens beneath you, grabbing your vehicle or drawing you in with the current as it swallows you whole. Alternatively, it could be dead, having grown too large to feed itself. Inside its open mouth, you could explore into it’s belly, where might find resources left behind from all the things it ate over the centuries. Perhaps you would find the pieces of a crashed ship or the remains of an otherwise unkillable leviathan. My second idea of an area with a path well-travelled by a dangerous creature was partially fulfilled with the Shadow Leviathan path in Below Zero. At first, I thought it was super fun to try and stealth around them, but they ended up being too perceptive and also didn’t really offer that much of a challenge when they caught you. Once I got the deterrent upgrade for the Seatruck, they turned into a joke. I think something much more fulfilling would be similar to your idea of the Seeking Leviathan roaming the larger tunnels of the catacombs, though more passive in its hunting approach. The biome would be mostly one massive tunnel, with smaller offshoots allowing hiding places or avenues to other locations. As you explore, you periodically feel the cavern shake, and soon after, the leviathan thunders through, mouth wide-open, blindly consuming anything unlucky enough to be caught in a section of the tunnel far from cover. For lore reasons, there would be smaller versions of the alpha leviathan, which may or may not pose a significant threat. They could inhabit a spawning cave circled by the path. The idea is that when the alpha dies, the rest fight for dominance of the main tunnel, eventually ending in one victor that is then able to grow to size and prowl the main tunnel. I think this area could be a very cool connecting piece between the areas of the map, offering fast access at the risk of being eaten if you aren’t careful. You may discover shortcuts that connect to this tunnel that aren’t obvious or aren’t traversable until you reach the biome it connects to for the first time, unlocking a “fast travel” of sorts.

[@Bamzerz]

YOOO THE KING HAS POSTED!

[@gaelschlupp9963]

I love all biomes you showed. I just hope that by doing so, Unknown World will still be able to use the idea/concept you outlined. Oftentimes, fanart and fanconcept are often disregarded for legal reason and can't be used by the company that developed said games (pokemon is a largely known example as fan art are massive < fakemon). Other than that, you did a fantastic job. I would love all your ideas to come to fruition.

[@snottytoe6957]

One thing I really really loved in subnautica that just wasn't part of below zero was the depth of it. I loved how far down some of the biomes went from the surface. I wasn't a huge fan of the caves, but I loved something like the sea treader path because from the surface to the ocean floor, it took almost a full minute of descending in the cyclops, and I loved the feeling of watching the sunlight disappear as you went down. It just had a sort of calmness to it that I loved.

[@kadenkingery]

again, i love the ideas for crush depth, with it being a more scarier game and stuff. i do hope that they make that idea, i love underwater horror games!

[@GhostBearCommander]

Possibly unpopular opinion: They need to include at least one Biome that is a small part of the deep void, with the only light sources being bioluminescent life forms, and wherein any attempt to venture beyond it simply ends in a large pair of unreal jaws engulfing you followed by a death screen.

[@everybodyants]

the emerald isle is my favourite. It is just sooooo beautifull. I imagine, that in upcomming multiplayer all players woud likelly rush to make their bases there. Super cool.

[@joetheeskimo8885]

I haven't watched you in a while so I got jumpscared by the puberty. Time flies.

[@emeraldislands]

I actually like the idea of the Rotnest starting small when you start a new game, and expanding a to predefined point as you progress through the story. The Rotnest biome would definitely make a great biome if it was added to Subnautica 3, would give me chills when encountered and exploring.

[@Ninjaspazboy]

OH MY GOD HE FINALLY UPLOADED IM SHAKING AND CRYING RN

[@dylan75217]

bro with these ideas you need to be hired.

[@gunnisoncornish4130]

I’d LOVE to see all these biomes

[@ThommyofThenn]

I do really like the heightened sense of danger in these ideas. Then facilitate the player to feeling more like a scientist by finding a way to counter the effects of the biomes. Maybe the PDA is damaged by the electric field around early/mid game, for some fun "puzzle" objectives! Neat ideas

[@user-rm4fi1tj6j]

Nice video keep the work

[@SpeedyMouse]

Thank you :)

[@user-rm4fi1tj6j]

Your welcome :)

[@alexanderclemons380]

i am a huge fan of the first game ive played it many times and i love the challenge it gives me when i play it and the first time i have ever played it i was scared to the bulb zone and any where near the darkness in below zero(i got it when it was in early release) only played it for about 2 hours it just doesnt give off the same feeling like the first one did

[@gagekelley5047]

i have an idea for a creature in the magnetic fields. though it isn't named yet, is has an spherical membrane around a soft body, with what look ball-shaped eyes at the end of stalks, which are in fact magnets. it would use the magnets to attract itself to a from the various creatures and magnetic areas, using unique mono pole magnetic fields. it would simply switch which pole the magnets acted as. it also has short tentacles around the occasions opening in its membrane, allowing food in. its main body would also be mostly spherical, which supports that connect to its outer membrane. it only eats the small creatures, being about the size of the crabsquid, but would use its abilities to push away predators with extreme force. also, its blind, so it uses magnetic field like a sort of sonar, and detect electrical transfers nearby, similar to a platypus.

[@SpeedyMouse]

Yeah, that's actually a great idea, I really like it!
