Subnautica 2 beginners should focus on scanning everything, managing oxygen, marking locations with beacons, building a small base, and upgrading the Tadpole early. Key tools like the Wake Maker, air bladder, Sonic Resonator, and Depth Module MK1 make exploration safer, while good planning helps players survive longer dives in the Early Access version.
Subnautica 2 is an underwater survival adventure game set on a new alien ocean planet. Like the original Subnautica , it asks players to explore a dangerous open world, gather resources, craft tools, build underwater bases, and survive strange sea creatures while uncovering the mysteries of the planet.
The game is developed by Unknown Worlds Entertainment, the studio behind Subnautica and Subnautica: Below Zero . Subnautica 2 entered early access on May 14, 2026, for PC and Xbox Series X|S. Its Steam page lists Unknown Worlds Entertainment as both developer and publisher, while Krafton remains connected to the broader franchise.
Because the game is still in early access, players should expect new updates, balance changes, new areas, new creatures, and more story content over time. Unknown Worlds expects Subnautica 2 to stay in early access for about two to three years before the full version is complete.
That makes the opening hours especially important. The game does not explain every system clearly, and missing one key scan, tool, upgrade, or survival mechanic can slow down your progress.
These 15 Subnautica 2 tips will help you survive longer, explore smarter, and avoid wasting time in the early-access version of the game.
1. Scan everything as soon as possible One of the first things you should build in Subnautica 2 is the scanner. Once you have it, use it constantly. Scan fish, plants, wreckage, tools, fragments, blueprints, strange structures, and anything else that looks important.
Scanning is how you unlock many of the game’s most useful items. If you rush through wrecks or points of interest without checking every corner, you may miss a blueprint that blocks your next upgrade. That can leave you swimming in circles, unsure of what the game wants you to do next.
This matters even more around wreckage and abandoned structures. Some scannable objects do not look important at first, so pull out the scanner whenever you enter a new area. If the scanner shows yellow dots, use them as clues. They can point you toward scannable items nearby.
2. Get the digestion adaptation early At the start of Subnautica 2 , your body cannot safely digest much of the local food. That makes hunger more stressful than it needs to be, especially while you are still learning where to find resources.
To fix this, look for the large plant-like structure near the starting area. Several beginner guides point players toward a glowing purple or pink plant close to the life pod. Interacting with it gives you the digestion adaptation, which lets you catch, cook, and eat local fish without the same early penalties.
This is one of the best upgrades to get early because it makes food management much easier. Instead of relying only on the limited food and water in your pod, you can start using the wildlife around you to survive longer trips.
3. Build a simple base early You do not need a huge base to get started in Subnautica 2 . A simple corridor, hatch, and power source can be enough to create a safe place with oxygen and storage. This is useful if you keep running out of inventory space or need a reliable place to craft and regroup.
A small starter base also helps you avoid depending too much on the life pod. Once you have storage containers and basic power, you can organize resources, prepare for longer dives, and craft without constantly swimming back and forth.
Mini bases can also work as oxygen pit stops while exploring. If you are still using solar panels, build them in areas with enough sunlight. A small powered corridor can give you a safe place to breathe if your main base loses power at night or if you are exploring away from home.
4. Use beacons to mark important locations Subnautica 2 does not give you a traditional map, so it is easy to lose track of useful places. Beacons solve that problem. Use them to mark your base, resource caves, wrecks, new biomes, dangerous areas, and any location you want to revisit later.
Beacons are especially useful when you find a cave with rare materials or a wreck with items you cannot fully explore yet. Instead of trying to remember the route, mark it and come back when you have better tools, more oxygen, or a stronger vehicle.
You should also place a beacon on your main base and change its color to something easy to see. That way, your home does not get lost among the other blue signals across the map. Clear labels and colors can save a lot of time once your screen starts filling up with markers.
5. Craft the air bladder and manage oxygen carefully Oxygen is one of the biggest early threats in Subnautica 2 . Before you have better tanks, faster movement tools, or a reliable vehicle, every dive is limited by how quickly you can reach air. That is why the air bladder is one of the most useful early tools.
The air bladder can help you rise to the surface quickly and can also give you extra breathing time while diving. Some players may want to carry more than one during early exploration, especially before they have stronger oxygen upgrades.
Do not rely on the air bladder alone, though. Watch for oxygen plants, air pockets inside caves, bubbles near wrecked structures, and places where you can build small oxygen outposts. Upgrading your air tank is also important because longer dives mean more time to scan, gather resources, and explore without rushing back to the surface.
6. Build the Wake Maker early The Wake Maker should be one of your early priorities in Subnautica 2 . It works like the game’s first major movement upgrade, giving you a faster way to swim before you have stronger vehicles or deeper exploration tools.
That matters because early movement can feel slow. The longer it takes to travel between your base, wrecks, caves, and the surface, the more oxygen you burn just moving around. The Wake Maker helps you cover more ground, reach points of interest faster, and return to safety with less stress.
To build it, you need to scan multiple Wake Maker fragments. These fragments are scattered around the early map, so this tip also connects back to the most important rule: scan every wreck, crate, and suspicious piece of equipment you find. Once you unlock the Wake Maker, exploration becomes much smoother.
7. Attach storage to the Tadpole The Tadpole is already useful because it gives you a mobile source of oxygen, but it becomes even better when you use its hard point. You can attach portable storage to the back of the Tadpole, giving yourself more room for resources during longer trips.
This is easy to miss because the attachment point is small, but it is one of the best quality-of-life tricks in the game. Early inventory space fills up fast, especially when you are collecting titanium, copper, quartz, silver, food, water, and spare tools. Extra Tadpole storage means fewer return trips and more time spent exploring.
You can also use the Tadpole’s attachment system for other utility items, such as work lights or oxygen generators. For most beginners, though, portable storage should be the first thing to try. It directly solves one of the biggest early-game problems: running out of space before you are ready to go home.
8. Upgrade your character with Bio Beds and Biolab perks Subnautica 2 is not only about upgrading your tools and vehicles. You can also upgrade your character. Hidden facilities and Biolab stations can unlock useful abilities and passive improvements that make survival easier.
Some early Biolab choices include active abilities such as Dash and Pathfinder, as well as passive abilities that help with oxygen use or movement near surfaces. These can be changed later, so you do not have to treat the first choice as permanent. If you are still learning the map, Pathfinder can help with navigation. If you are more comfortable exploring, Dash can help you move faster and avoid danger.
You should also interact with Bio Beds whenever you find them. These can give upgrades such as more inventory space, better endurance, faster equipment swapping, or extra hotbar space. Because inventory is so limited early on, even a small upgrade can make a big difference during resource runs.
9. Manage base power before you overbuild Base building is important, but do not expand faster than your power supply can handle. A larger base needs more energy to keep oxygen flowing and equipment running. If you build too much too early, you may end up scrambling to add solar panels just to keep the lights on.
Solar panels are cheap and useful at the start, but they have limits. They only work well in areas with sunlight, and they do not solve your power needs at night. That makes them fine for starter bases and mini oxygen outposts, but less reliable as your base grows.
As you progress, look for better power options. Hydroelectric turbines can provide more consistent power when placed near currents, while later options such as the bioreactor can help support a larger base. The main rule is simple: build for what you can power, not just for how much space you want.
10. Build and use the Sonic Resonator The Sonic Resonator is one of the most important early tools in Subnautica 2 . It helps you harvest large resource deposits, which makes it easier to gather materials once basic loose resources are no longer enough.
It also supports progression in other ways. The Sonic Resonator can clear certain blocked areas, remove bloom webbing, open access to new fragments, and interact with corrupted roots or branches tied to later upgrades. In some cases, it can even help create or access air sources while exploring caves.
Because of that, do not treat the Sonic Resonator as optional. Once the game starts sending you toward deeper areas, hotter zones, or blocked paths, this tool becomes part of your core survival kit. Scan the fragments when you find them, build it early, and keep it with you when exploring unfamiliar biomes.
11. Pay attention to creature sounds The ocean in Subnautica 2 is not just dangerous because of what you can see. It is also dangerous because of what you can hear. Creature sounds can warn you when something nearby has noticed you, become aggressive, or is about to call in more trouble.
This is especially useful in the early game, when oxygen, food, and water are often bigger threats than combat. Some aggressive creatures make clear audio cues before they attack. The forey, for example, has a high-pitched siren-like trill when it becomes aggressive. The nibbler mango can be more dangerous in groups, and its clicking trill can signal that it is becoming hostile. It can also scream and draw larger predators toward you.
Play with sound on when possible, especially when exploring caves, wrecks, or unfamiliar biomes. If the music shifts, a creature starts clicking, or something nearby screams, stop rushing forward. Look around, check your oxygen, and decide whether to retreat, distract the creature, or keep moving.
12. Find the Depth Module MK1 to keep progressing The Depth Module MK1 is one of the key progression items in the current early-access version of Subnautica 2 . If you feel stuck after reaching the larger plateau or open ocean areas, this may be the upgrade you are missing.
The Depth Module MK1 increases the Tadpole’s safe exploration depth, which allows you to take your vehicle farther down without constantly abandoning it. One transcript describes it as a bottleneck because the explorable area opens up so much that it becomes easy to wander for hours without finding the next required upgrade.
Once you have the module, deeper areas become much easier to explore. You can stay closer to your vehicle, use it as an oxygen source, and search the seafloor without making every trip feel like a risky swim back to safety.
13. Pin recipes before resource runs Before you leave your base or life pod to gather materials, pin the recipes you are working on. This keeps the required resources visible, so you do not have to memorize every ingredient while exploring.
This is a small feature, but it saves a lot of time. Early in Subnautica 2 , you may be trying to build several things at once: a scanner, air tank, base parts, the Wake Maker, storage, batteries, or other tools. Without pinned recipes, it is easy to return home and realize you forgot one piece of copper, quartz, silver, or titanium.
You can pin recipes from the fabricator and remove them later by returning to the recipe and unpinning it. This is especially helpful before longer resource runs, when inventory space is limited and every slot matters.
14. Move base equipment instead of rebuilding everything Do not worry too much if your first base layout is messy. Subnautica 2 lets you move equipment with the habitat builder, so you do not always need to deconstruct and rebuild every object from scratch.
This is especially useful for storage containers. Once a container is full of resources, moving it is much easier than emptying it, deconstructing it, rebuilding it, and putting everything back. The same idea applies as your base grows and you start reorganizing your crafting area, power setup, or storage layout.
Deconstruction is still forgiving because it returns materials, but moving equipment is faster and cleaner. Treat your first base as something you can improve over time instead of something that has to be perfect from the start.
15. Use Three Moon Temaki for long trips For longer exploration runs, Three Moon Temaki is one of the most efficient foods to bring with you. It gives strong food value and some health, which makes it useful when you are far from base and do not want to waste inventory space on several smaller food items.
To make it, you need fibrous pulp and the three moon fish variants: half moon, blue moon, and harvest moon. The transcript notes that these fish can be found near the starting life pod, while fibrous pulp can be gathered by cutting plants. You will need a proper base fabricator, not just the life pod fabricator, to craft it.
This tip becomes more valuable once you start making longer trips into deeper or more dangerous areas. Pack water, bring emergency oxygen options, and use efficient food like Three Moon Temaki so you do not have to turn back just because your food meter is low.
Conclusion: survive smarter in Subnautica 2 Subnautica 2 rewards patience, preparation, and curiosity. The more you scan, mark locations, manage oxygen, upgrade your Tadpole, and plan resource runs, the less time you will waste swimming in circles or returning to base empty-handed. Since the game is still in Early Access, these systems may change over time, but the core rule remains the same: explore carefully, prepare before long dives, and use every tool the game gives you.
