What Will Subnautica 3's Biomes Look Like?

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!! :)

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.

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.

i feel like the rotnest have potential to be the first actually hard zone in subnautica.

I really like the concept of the “rotnest”. It reminds me of the flood from Halo, very good

5:13 : "making it easy to become lost and disoriented" path finder tool: 👁👄

Hopefully the devs at UnknownWorlds will listen to their fan base and make a good game Edit: im not at all saying they made bad games. I liked both games

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.

Here’s an idea for the catacombs, if there is an inaccessible cave that’s too small, you could craft a drone/robot kind of thing to explore the smaller areas of the catacombs!

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.

Bro why haven’t unknown worlds hired you as a concept artist all of this is absolutely amazing!

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. Absolutely need this one in Subnautica 3!!!

I like the idea of some kind of gulf stream like biome spanning throughout the world like how the kelp forests snd sea treaders path did in the original game

Yo always great to see a new Speedy vid! :)

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

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!

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

A swamp biome with murky water would be cool

For the magnetic resistent tools, i was thinking a special kind of battery as alternative to the ion batterys

I feel like another good reason to why the rot nest biome’d be so deep, is because maybe the rot nest can’t have much sunlight otherwise it starts killing it. But recently it’s been evolving to not deal with that issue
