Building a base in Subnautica can be a rewarding and strategic part of the game. Here are some tips to help you create an efficient and enjoyable underwater habitat.
Experimentation and Hull Integrity
One of the best ways to learn base building in Subnautica is through experimentation. You can freely build and deconstruct without losing resources, allowing you to try different designs [1:1]. Pay attention to hull integrity; if it drops below zero, your base will flood
[2:6]. Reinforcements made with lithium are recommended over foundations for maintaining hull integrity
[2:3].
Location and Orientation
Choosing the right location for your base is crucial. Consider starting your base on taller terrain to avoid collision issues when expanding [2:1]. The direction of your foundation will determine the orientation of your moonpool's exit, which can affect vehicle docking
[2:5].
Power Sources
Solar panels are often sufficient for powering your base unless you're deep underwater [2:7]. If you need more power, consider using a bioreactor or thermal plants, especially in areas like the Lost River
[4:1]. Breeding Reginald fish in an alien containment tank can provide a steady supply of bio-fuel
[2:8].
Base Components and Layout
When designing your base, keep essential components like fabricators and storage close together to minimize time wasted running back and forth [2:3]. Multipurpose rooms can serve as central hubs, while scanner rooms can help locate resources
[5:4]. Be mindful of the alignment grid set by the first piece you place
[2:4].
Exploration and Resource Gathering
Before focusing too much on base building, prioritize exploring wreckages and scanning parts to unlock blueprints that make construction easier [5:2]. Stockpile essential materials like copper and silver, as they are frequently needed
[3:1]. Use beacons to mark important locations and aid navigation
[3:3].
By following these tips, you'll be well on your way to creating a functional and aesthetically pleasing base in Subnautica. Remember to enjoy the process and adapt your strategies as you discover new areas and technologies within the game.
I bought subnautica yesterday and i unlocked that tool for building base. Aby tips for building it?
If it ever seems like a base piece doesn't connect for seemingly no reason, a locker or something similar on the inside of the connecting wall will block it
Spoiler
Use cyclops to transport resources for base building if building in something like the lost river or farther away cuz theirs like 12 lockers in there
Find a suitable spot and just go nuts. The best way to learn in Subnautica is by experimenting. Plus you get all resources refunded when you disassemble a base piece, so feel free to build up and tear down your base however much you want as you experiment. The only thing it'll cost you is time and battery power in your habitat builder.
One thing I will note, though, is to pay attention to the hull integrity value that pops up in the top left whenever you build or remove a base piece. If that value goes below zero, your base will start springing leaks. Thus, always keep it above zero. If necessary, build pieces that add to your hull integrity such as reinforcements and foundations.
Also, as long as your base has power, it'll have air in it. Don't make the mistake of thinking you'll need to pump air down to it from the surface. Lots of new players make that mistake.
I’m new to the game and I’ve got a habitat builder. I’m playing around with the habitat system and planning to have each major part of the base go to each one of the pillars of rock in the picture. Sorry if the pic isn’t clear enough. Anyway, like I said I’m new to it so any tips on base building and the game in general would be great. Also, I do know there are better places for a base to be
Tip: If you want a multipurpose room on each pillar and want them all joined up, you might have to mess around constructing, deconstructing and realigning them until you get them all in the right place --connected base pieces must all align to a grid, and the alignment of that grid is set by the alignment of the first piece you place. Good luck!
A good rule is to build a foundation first, in the direction and position you'll want all your base to be. The grey part of the foundation will point in the direction of the moonpool's exit.
Good tip —this is the direction the seamoth will face when docked? My current base, has the seamoth facing away from the exit, which I find is convenient enough
great location imo. tips? reinforcements are much better than foundations for hull integrity. try to keep things like the fabricator and storage all in one place. seen so many run back and forth wasting time. build a lot of solar panels. then the bioreactor. I usually put down a foundation and make 6 of them. scanner and hud chip asap.
Yeah, I was gonna have maybe three solar panels, one bioreactor and the fabricator, the radio and some lockers to start before I build anything else
Once you have the bioreactor up and running I suggest getting an alien containment tank set up nearby and use it to breed Reginald fish. They are the second best natural bio-fuel source and also double as the most effective (fish) food source.
I go ham on the solar panels because copper off the reefbacks is pretty sweet and easy. and quartz is too in the red grass. not worrying about power is great. then when you add scanner room or moonpool you don't have to powering up first. and there's a big reserve so your bioreactor doesn't eat so much.
Wgen you are able to, go to sea treader's path, and use the Alien Feces as fuel. It's the best for the Bio Reactor and the Sea Treaders are friendly
Watch your structural integrity. That is one of the most important things to remember. Go negative and your base will flood. Foundations made with lead and reinforcements made with lithium are pretty much mandatory
For power, unless I am deep in a cave I use solar power and nothing else. Nothing else is needed. You can run everything you need, including multiple water purifiers. 2 purifiers make more than I can drink.
Start growing food plants as soon as possible. Once you start growing the right foods you won't need water. You will get all the water you need from the juicy food you eat.
If you find the alien containment throw a couple of bladderfish in there and you will have limitless water. Same goes with the reginald or peeper. Throw a pair of those in and you will have limitless food. I prefer being a vegitarian in game though, it's simpler.
Do you need to throw two of the same fish to breed?
One trick with bases is that once you put down the first room (or component), the orientation and height of your base is set. I'm not sure which of those rock pillars is taller, but you should probably start your first room on the taller pillar, so that by the time you extend your base to the second pillar, what happens is just that the legs underneath are slightly longer.
Doing the opposite, starting on the lower pillar, may mean that you can't build because the taller pillar's rocks collide with the position where the room needs to be.
Just recently got into it. It took me way too long to finally get going in this game(couldn’t find cave sulfur haha) with that said hoping for info on things to make the game more enjoyable in the long run. I just got to the island. Debating about starting a 2nd base there. Thinking about putting beacons everywhere too
If you want to obtain maximum fun out of Subnautica and have one of a kind gaming experience, shut your internet off and play the game completely blind until the end.
You can play it however you wish or think that it would be fun for you. There's no one correct way to play.
Incidentally, you must/should/have to scan everything and read every PDA entry.
I was initially staying away but the cave sulfur was holding me back. I watched a video and it was the biggest “your joking me” i checked those sacks all the time and it never poped up for me. So I’m just worried about missing things like that.
Don't worry. You can't miss anything if you are a little bit observant and willing to explore.
The most common regret I read/heard from players is that they wish they wouldn't have rushed the gameplay to end the story in their first playthrough.
You can only play Subnautica once as the first time.
Beacons definitely help you find your way around. Make sure to name them. I upgrade my air tank as quickly as possible too
I change colors on mine too. Base beacon is different than, say, dive points. Vehicles are yellow so they stand out more, etc.
Make yourself an air bladder, super useful for rapid surfacing, avoiding those exploding fish, and a little emergency air. Also eating bladder fish raw gives you a little oxygen also.
Beacons are good.
Also, be brave. I gave a up on my first run or two because I was super worried about dying and ended up dragging out the early game enough that I got bored before going more than a few hundred meters deep. Dying isn’t super punishing so take risks and explore.
Stockpile copper and silver. Crack every limestone and sandstone node you see, you need an annoying amount of both.
Inventory tip? It sucks losing out on space, but carrying an extra oxygen tank (upgraded) means you can switch out underwater and drastically increase the time you can spend away from air.
Also, (I didn't figure this out til like my fourth run through) you can eat raw bladder fish for 12 units of oxygen. Need to get something that's really deep and cant get down there yet? An extra oxygen tank and a bunch of bladder fish in your inventory and you can do anything. They do dehydrate you a little, so be careful with your water.
Sooo... I need some help 😅 This is my second time playing Subnautica. The first time, I didn’t even make it to the >!Lost River!< — but this time, I actually got there!
Thing is... I’m extremely scared of literally anything even remotely creepy in this game 😬 So now I’m procrastinating instead of exploring further. My procrastination plan? Building a better base 😂 But I kinda suck at it. Right now, I just have a tiny base in the Safe Shallows made of a few corridors, a Scanner Room, a round room with some storages... and a floating moonpool — it’s super cramped and honestly kinda ugly. (Image attached)
Any tips or suggestions for building a good-looking and efficient base in a nice biome? Please help 😭🙏
I HIGHLY recommend going into Creative and playing around with base construction in the different areas you want to build in. Not only does it help you get a visual of what you want without having to worry about oxygen or battery/material consumption, you can also get used to being in whatever biome you choose and find ways to navigate around all our aquatic "friends"
You should build a base in the lost river. That way, you have a safe place nearby to help you feel safer about exploring. Plus, it has great spots for thermal plants.
If I build a base there, won't the big ghost worm try to eat me and destroy the base? :0 If he doesn't attack, I think it's a great place indeed. Ty!
There are several, but they don't wander far from where you see them. The smaller aggressive creatures are more widespread, but they only attack you or your vehicle. If it's up in a moonpool it will be fine, and your cyclops is safe from them as well. Just have to make your way past the big ghost leviathans.
You could make the moonpool your whole main base if you wanted and just put all your lockers, fabricator and stuff on the walls in it. The only thing you can’t put in there and would need a large room for is a Bio or Nuclear Reactor if you were using that for power, or an Alien Containment if you wanted an aquarium for feeshies. If you’re using solar or thermal power you can just put everything in the moonpool if you wanted. You could also have a few corridors on the moonpool walls to give yourself additional room for storage or whatever else.
I didn't even know you could put connected corridors in the moonpool 😅 ty!
You can put just about anything on the walls of it that you can put in a normal room. I’ve never tried putting the water filter machine but I’m pretty sure that can too.
Ok so start by building out foundation maybe 6 to 8 to make a big enough space then go from there . Start with the X Compartment and do 1 multipurpose room, 1 for the scanner and 1 for your moon pool
ALSO don't afraid to make them 2 story habitats
Wow, I didn't even know you could fit the moonpool in with other places. Ty!
play it in the creation mode. explore at your rythm. no death, no oxygen, no food.
this helped me with my thalassophobia. just don't forget about the oxygen when retuning in normal mode
I am an absolute noob when it comes to building bases. I’m not super far into the game but I can’t even make a cohesive square of tube right outside my life pod. Anyone got some builder tips? Anytime I look anything up online I get more spoilers.
Spend less time on building a base right now, and more time looking for wreckages and things to scan in the world.
There are many blueprints that will make building much, much easier, and they are only found by scanning parts or wreckages. If you need more storage space, just build a couple tubes in a line and fill them with storage and essentials, to act as a storage unit.
Better yet find the scanner room blue prints and scan for blueprints
Also hud chip comes in handy
Scanner room was the first blueprint I found, before any general rooms or compartments, so for the longest time my base was just the scanner room with a door. It was actually pretty nice!
You said "life pod". If that's what you meant, then you should know that you can't add or build onto the starter life pod. You need to find and scan other base parts (like the basic room or large room) and build a base from that.
And then with that.. yeah, base building can be a little rough. you need to make sure the part is rotated the right way (try turning thingd 90 degrees - like the monopool or scanner room). and then swim in and out and move camera so it moves closer and farther. sometimes the right place to drop it is father away then expected for it to attach since it has to add a little connector when you add into the larger base pieces.
Try building in the red grass biome, its open its beautiful its safe, all you need is a tube a hatch and a solar panel and you are ready to go
Keep it simple. Don’t overthink stuff. A simple base is a happy base.
There’s a base piece you can find and scan that makes building much better. Pretty rough to do much of anything when you just have the tubes
So, in Subnautica 1, if I remember correctly, oxygen was auto-magically generated inside bases without some sort of electrolysis system which should require space and power to operate. Also, the base was completely immune and ignored by leviathans, allowing you to build one inside their lair.
Should base building become a little more hardcore so survival is actually a little more difficult this time?
Also, I would love to see an actual airlock system that requires power to operate, instead of us being able to just open and close a door at 10km depth! 😆
I think that leviathans should be able to attack bases, but if that will be the case there should also be a sort of a repellent. Maybe a base compartment which creates a sort of safe space around the base at the cost of some piwer.
I like that idea. Wanna build very deep and in a biome where good resources are, but also where leviathans hang out? Fine, but shell out a bit extra for protection.
Or just make it in the tree cave
That might be neat, but I do think it would be cool to just force you to live with the consequences of building a base near an active threat — or at the very least not let the repellent work on everything forever. Like if you're asking to be eaten that much with your base location, the game should punish you for it and not give you an easy or reliable way to bypass the threat IMO.
Make it a setting. Toggle between "vanilla basebuilding" and "difficult basebuilding"
Ye, especially the airlock idea, I forgot some random material so often and had to quickly head back and I think I'd have lost it if I had to go through a lengthy airlock sequence every time.
I just think about Avatar: Frontiers of Pandora Every fucking time i got in a (human) base and had to wait till i finally could enter/leave. Naaa i don't need that in Subnautica
I would just only build moonpools and never an airlock.
As a long term fan of project zomboid, keep it there, please, do not bring these kinds of mechanics for those games to ones that do not reflect them. People do not play Subnautica for realism.
A lot of your complaints can be implemented into SN1 by simply roleplaying choices.
Hardcore is pretty difficult and tedious if you avoid using vehicles completely.
You can put “airlocks” in your base via the bulkhead door.
No bulkhead door yet? Your base is then restricted to being build above water level.
Or you could put your entrance on the bottom of your base pieces.
Well, oxygen production systems were built into the frame of the structure pieces you fabricate, it required external power to function. You have to remember that Subnautica is not a base building sim, it's operation is simplified to keep the flow of the game pleasant for most people.
I think this is the correct flair? This is like my 5th ever run on subnautica, coming back every year or so and completely forgetting how to play it. I always try to build bases in new places so the game doesn't get boring (it rarely does anyways). Shame on me for using a map but I have a horrible memory. had these 3 spots in mind for a base. 1st is east of floating islands. I think it's quite a good location but the bonesharks are a nuisanceeeeee. 2th is a spot in the mushroom forest bordering with a few biomes on the north of the map (next to wreck 12). It's cool but a bit boring I guess? The third one is the cliff side of the blood kelp zone. Any tips or recommendations? Thank you, have a wonderful day! :3
I normally build in the sw grassy plateaus or the nw mushroom forest
Misunderstood the post but I'd say blood kelp trench
That's what I chose, thank you :3
I usually just make a cyclops into my base.
That's great, that's surely a way but I need an actual base. Moonpool, scanner room and generally just comfort.
Edge of the BK Trench is my favorite spot.
Very easy access to all resources. Lost River and thermal power nearby.
Just… don’t go too far north.
HAH I made that mistake.. Never loaded a save faster in my life.. Thanks though! :3
Blood kelp trench (option 3) ftw
Especially if you want your >!cyclops down in the LR!<
Okay thank you!!
I’ve built at spot 2! Near the blood Kelp and those two mountains near the floating islands is a good outpost imo, but I struggled with materials a small bit. My main base was elsewhere. The locals are nice, you’re not far from the shallows, not far from the deep end.
It’s a good spot for later game play with quick access to relevant areas. >!The cyclops has a path into the LR!< near that area, but I’ve never personally >!driven my cyclops into the lost river through that tunnel thanks to the Friend outside it!<
Okay thank you so much. I'll probably choose that spot :)
Just some things I've figured out so far. If you have more advice, please share!
Don't use foundations. You have to deconstruct everything if you decide you want to remove them - whether for aesthetics or as part of a base expansion. Lead is particularly annoying to gather, too. Use Reinforcement Panels (Lithium) and Bulkheads (Rubber) instead. You can hide a bunch of I pieces out of sight and cram them full of Reinforcements and Bulkheads to create as much hull integrity as you need in a compact "farm".
Build in a line, erase the middle, and it's still considered a single base - sharing power and hull strength. You can continue building the line further and keep removing pieces from the middle. This can be used to create remote power generators without ugly power transmitters. Your base at -300 meters can collect solar power from a "floating" platform. This technique can also be used to create remote hull strength "farms".
Avoid placing Lockers next to windows/reinforcements, otherwise you won't be able to deconstruct them without first emptying and deconstructing the Locker, which can be a pain. Multipurpose Rooms need even more space if you want to connect a new room, as the connector has handrails that extend into the room.
Building rooms immediately next to each other is really restrictive and short-sighted. Adding a Glass I Compartment between every room in your base is aesthetically pleasing and highly practical. You can install Hatches and Bulkheads in them for more hull integrity and easy access in/out of every corner of your base. And building this way makes expansion and reconfiguration easier. A hatch can be swapped with a vertical connector with no additional work. The compartment can be swapped with other types to create new branches between rooms - avoiding the need to relocate lockers or your garden or whatever.
Ladders are teleporters. Building your base vertically can save a lot of time over the course of a campaign.
The orientation of Ladders and Moonpools is determined by the very first base piece you build.
When you dock in the Moonpool, you exit the Seatruck to the right and the Prawn Suit to the left.
Even with unforeseen base expansions down the road, you can ensure your Moonpool will be easily accessible from all directions by building the rest of your base on a completely different level than the Moonpool. I'll say it again: ladders are teleporters.
You don't really need a Moonpool, just a Power Cell Charger. I know that lengthy dock/undock animation can get old.
Two Water Filtration Units drain slightly more power than one biofuel reactor can generate, which can be pretty annoying if it catches you by surprise.
Scanner Rooms actually aren't very useful in your main base. Treat them like a bulky, clunky Mineral Detector that requires an entire Seatruck Storage Compartment to lug around. They were more useful in Subnautica than Below Zero, to be honest.
Building a large base above sea level is hard. The main technique that's helpful is using I Compartments as scaffolding and ceiling/floor hatches to gain height.
Good post. The tip about splitting bases but still having energy is very neat
>Scanner Rooms actually aren't very useful in your main base. Treat them like a bulky, clunky Mineral Detector that requires an entire Seatruck Storage Compartment to lug around. They were more useful in Subnautica than Below Zero, to be honest.
They're a bit less useful because they suck on land, but they're fine in the water. They're about equally useful for finding particular resources, lead, nickel, lithium. The fragment scan can help you find sea monkey nests, light up parallel processor parts, etc. If your main base is in the twisty bridges, but near the vent zone/island, a long scan can pick up most resources in game game.
I'd say about one-third of the question posts on this subreddit could be fixed by the player just building some scanning rooms.
That said, the Command Room is useless lol
I quite like my pink base with yellow trim, I call it the easter egg!
Good post! You kinda mentioned it but I like stacking an empty multi purpose room below my multi purpose rooms, it’s then easy to add reinforcements to every side of the empty room and windows to the real room. Looks nice ��
This is nice to do with storage, since I like having windows on all empty walls. Just add a floor below the main one with reinforcements and lockers + a few planters to keep the nature going
> You don't really need a Moonpool, just a Power Cell Charger. I know that lengthy dock/undock animation can get old.
But popping power cells out of a vehicle and lugging them to a charger won't get old? I don't think this particular tip has been thought out very well. :D
You don't need to recharge power cells with every visit to your base. Omitting that is where the time-saving happens.
Just keep spares in your storage module and swap power cells out when they're drained. Grabbing drained cells from storage simply becomes part of your normal process of unloading your Seatruck after a long excursion.
You dont need too pop them in and out. Just trow the old ones in the trash and build new ones.
Important thing to add: power connectors are broken and don't work. To establish a working Power line you need to set the source and then move from the source to the base. If you want to add a second source on the same line you need to re-do the whole process.
Great tips, OP. I honestly didn't know about a few of them, like #2, and I was already starting to realize #1 as well. Foundations were important in Subnautica, but seem irrelevant in BelowZero, or worse, a pain point. Once you have bulkheads, that is a much easier way to go.
I would like to add that I know a lot of people recommend two water filtration units, but I found that as time went by, I really only needed one. Although I have a well-stocked greenhouse.
I made myself a habitat builder but there is no room blueprint or anything that I can place to start making the base. Any help?
You don't need the big rooms to make a starter base, almost everything can be built in the corridors
You have to scan the structures first in order to be able to build them. Explore the map to find them, or just follow the storyline and it will eventually lead you to them.
Is there any specific spot where the room is supposed to spawn
The base rooms you can scan are always on the same predetermined spots on the map, but I really don't wanna spoil that for you - it's a cool discovery to make organically, and in the meantime you can use the tube structure that comes with the habitat builder, they basically work the same.
The first base I ever built was a 4-way with a hatch. It's all I needed for a while.
