Subnautica 2 is finally among us, despite its major legal woes. The game’s early access debut has drawn in over 400,000 concurrent players on Steam within its first half-hour and surpassed one million copies sold almost immediately.
And just like any sequel (from the first Subnautica and the spin-off Subnautica: Below Zero), there are a lot of new features and nifty little things that even the most veteran players of the first game will find themselves struggling to get their bearings in.
Luckily, our ever-resourceful team is here to help. Keep reading our full Subanautica 2 beginner guide to get ahead on the game’s new shenanigans and get your edge on exploring the dangers of the deep seas.
Prioritize the Scanner and Technology Blueprints
Much like the first game, Subnautica 2 also features a scanner device that is, in no uncertain terms, vital to your diver’s arsenal. Granted, such an important piece of equipment should be your first, second and third priorities.
Not only because of its most obvious features, which entails monitoring the seas to anticipate whatever is close to you and allow you to take action (or risk becoming carpaccio for the most dangerous predators), but the scanner is also a bit of an entry point for crafting other useful items. Without it, you cannot unlock the blueprints required for advanced tools, base components, or vehicles.
So, yeah, get around to build one, pronto! For that, you’ll need two Titanium, two Quartz, and one Basic Battery, the latter of which is crafted using Copper and Acidic Raion Pouches. Once equipped, make it a habit to scan every fragment of wreckage, unfamiliar flora, and creature you encounter.
This way, you’ll find all fragments of all equipment and essentials you’ll need to improve your odds of survival.
Unlock Permanent Biological Adaptations Early
Unlike previous installments, survival in this environment is heavily tied to Adaptations found in specialized chambers. So you really should give this part of Subnautica 2 a much warranted early attention.
Now, Adaptations are not “researched”. Instead, they are found and activated through sheer exploration and interaction.
The most critical early-game milestone is locating the Digestion Adaptation, situated roughly 180 meters north-north-west of the starting Lifepod. Interacting with this structure permanently allows your character to digest the local fish, solving the primary challenge of food sustainability.
Additionally, keep an eye out for Colony Habitats indicated by blue standing lights; these often house Biobeds, which can be used to permanently increase your character’s inventory capacity and hotbar slots.
Master Oxygen Management and Emergency Surfacing
Remember Dave, the Diver? In that game, you had to keep an eye out for your oxygen expenditure in order to ensure a successful deep-water exploration. The same concept applies here, albeit with a little bit more depth.
In Subnautica 2, your starting oxygen supply of 45 seconds is extremely restrictive, making early cave exploration a high-risk endeavor. To extend your dive time, your first major resource goal should be obtaining Silver—found in specific green-lit caves north of the spawn—to craft a Standard Air Tank.
This will allow you to explore more of the ocean, eventually finding abandoned research labs that contain fragments of a craftable item called “Air Bladder”. As the name implies, these are emergency respiratory items that you can take with you while diving, and give you that little extra air oomph. On deep sea cave explorations, having one or two of those is really handy.
Furthermore, Air Bladders also provide a rapid ascent to the surface, which is essential for escaping predators or reaching air when you have misjudged a cave’s depth.
Utilize the Sonic Resonator for Resource Gating
The Sonic Resonator is a versatile tool that serves as both a utility and a defensive device. It is required to break large mineral deposits and clear environmental blockages like Bloom Biofilm, which often gate access to rarer materials and story objectives.
Beyond mining, the resonator can be used to temporarily discourage aggressive smaller predators or destroy viral growths to unlock late-game adaptations like Heat Tolerance. Crafting this tool early is essential, as many materials like Lithium—found in the dangerous Great Jaw area—cannot be easily harvested without it.
But do not count on it against larger predators, such as the Leviathan—which, by the way, now comes in “types” that answer differently according to the player’s actions, but this is something for another entry on this list.
Strategy for Base Placement and Power Generation
Base placement is a strategic decision that affects your efficiency throughout the game. While the starting area is safe, beginners often find that building slightly to the east is more advantageous as the game’s progression naturally pushes explorers in that direction.
In other words, positioning your base in that direction will put you near underwater currents (visible as blue wind-like tunnels), which allow you to utilize Hydroelectric Turbines. These provide constant, reliable power, unlike Solar Panels which fail at night or in deeper waters.
A well-placed base should also include a Scanner Station, which can pinpoint specific resources like Lead or Silver within a 300-meter radius, drastically reducing time spent searching blindly.
Enhance Mobility with Biomods and Vehicles
Restoring power to the abandoned Welcome Center southeast of your Lifepod with a Basic Battery grants access to the Biolab, where you can equip Biomods. The Dash and Oxygen Control skills are highly recommended early on for evading predators and maximizing your breath.
Eventually, you must transition to vehicles like the Tadpole mini-sub to reach deeper biomes. Ensure you prioritize the Depth Module and Repair Tool immediately after crafting your first vehicle, as navigating the abyssal trenches without them will lead to catastrophic hull failure.
Navigate Predator Territory Using Stealth
As we mentioned earlier, predators in Subnautica 2 are largely expanded. If the first game had only one Leviathan to scare you pantsless, this time around the Leviathan class (yes, class, as in “more than one”) boasts the Collector Leviathan, which is absurdly unpredictable.
There are others, of course (including one that developer Unknown Worlds speaks of as “something else”, found in the Void zone, which is still unfinished at the game’s early access phase—so, yeah, more enemies to swallow you in a single gulp, we reckon), but the usual approach for these is stealth.
What we mean by that is not much “move around real quiet”, and more like “don’t give it anything that facilitates them honing in on you”, because they will. Oh, they will. So when entering these zones, turn off all vehicle and flashlight illumination to reduce your profile. Moving slowly and staying close to trench walls or terrain edges provides cover and reduces the acoustic signature that attracts these hunters.
If you are detected, Distraction Flares can provide a brief window to escape, but the primary survival strategy should always be stealth and environmental awareness rather than direct confrontation.
Final Thoughts
The first Subnautica game made headlines for blending survival-horror features into something that most of us fear in real life: what lurks in the deep, blue ocean? There is a reason why people who suffer from thalassophobia (the fear of deep bodies of water, essentially) actively avoid this game.
Subnautica 2 doubled down on that effect, adding more reasons for you to be scared of traversing the ocean floor without knowing exactly what is down there. So surviving the game’s depths is a balancing act between cautious exploration and rapid technological advancement.
If you still dare, Subnautica 2 is available for purchase for PC and Xbox Series X|S.
