Subnautica 2 Guide Contains ten essential tips that are essential for surviving in the Early Access game.

Published by A Madadi at May 20, 2026

The main focus of the Subnautica 2 guide is on the crucial mechanics that are obscured in the game (this ambiguity occurs intentionally in the game). These ambiguities can be about managing oxygen during night cycles or finding elusive depth modules, etc. It goes without saying that these things are actually essential to progressing in the game. What you will find in the Subnautica 2 guide is that it covers important points from the basics of the game to the advanced and advanced parts of it.

We already checked out this game in the Subnautica 2 Review, so if you haven't bought it yet, I suggest you read that post carefully.

Subnautica 2 Guide
  1. Power Management and Oxygen in Early Access
  2. Storage Management and Scan Order in Early Access
  3. Battery Management and Tadpole Attachments in Early Access
  4. Key Resource Locations in Early Access
  5. Conduit Crystals and Depth Module
  6. Final Recommendations for Early Access

Power Management and Oxygen in Early Access

The first challenge you face in the game is the power outage at night. Obviously, solar panels are cheap during the day, but at night, they will be very expensive, causing a power shortage. Imagine a base where there is no oxygen. This base is like a coffin for death.

There is a solution to this problem. One such solution is to build a small base near your main base. You can solve this problem by building such a base near you. Note that this small base should include the following:

  • The small base should include a single chamber for oxygen intake and production.
  • The small base must include a solar panel to power the enclosure.
  • The small base should consist of four titanium pieces.
  • The small base should consist of two quartz pieces.

You need to expose this small base, called a secondary base, to sunlight. Having these bases will ensure that you have enough energy and oxygen reserves throughout the game. Although the deeper biomes do not support solar panels, the early game areas will support them well.

Storage Management and Scan Order in Early Access

Although players often expect these manual saves to work in a specific way, this is not the case. Typically, the game will reload after each death, triggering an autosave that is activated at the moment of death. If you want to effectively rewind time, keep these things in mind:

  • Create a manual backup before you attempt any risky activity.
  • If you die in the game, give up and don't try to save.
  • Instead of starting the game directly, go to the loading menu.
  • At this point, you need to select the saved file.
  • Restart work before an accident occurs.

Another part of the Subnautica 2 guide is about scanning. You must be able to thoroughly and accurately inspect shipwrecks, abandoned colony structures, and anything that looks suspicious.

Basic maps in the game are hidden on objects that aren't scannable. Note that ignored maps will hinder your progress in the game.

Battery Management and Tadpole Attachments in Early Access

You can use a non-intuitive mechanism to replace the battery. To do this, you must follow these steps:

  • First, you need to choose the tool you need for the job.
  • To select the desired battery, use the directional buttons (D-pad) and press them up.
  • You can switch between available batteries using LB and RB.
  • Finally, choose the battery that holds the longest charge.

You should note that you should usually carry one or two spare batteries. You use a vehicle called the Tadpole, which is capable of transforming early exploration. In addition to providing portable oxygen, the vehicle can also include hardware attachments such as portable storage containers. You can attach a storage container to the hardpoint of the vehicle to carry storage capacity during the game.

Key Resource Locations in Early Access

Strong Acid and Portable Launch Generator

It should be noted that the blueprint for the portable launch generator is located southwest of the Life Pod. You need to find the large clam-like creature. Note that inside its core, the vents are covered in lithium deposits. You will find two scanner pieces in this location.

The portable launch generator blueprint resides southwest of the Life Pod. Locate the large clam-like creature. Inside its core, lithium deposits line the walls. Two scanner fragments occupy this location. You should be careful of the tripwires and stay away from them, as they emit a deadly poison.

The strong acidic components come from the cysts of ancient reptiles. After passing through the large jellyfish, these reptiles go to the underwater purple forest and appear northwest of the Life Pod. You will see plants that are like balls with glowing roots. You can destroy all of these cysts using a multi-tool.

Avoiding the Collector Leviathan in Early Access

A giant squid called Collector Leviathan roams the cave systems and vegetated areas. It is capable of killing its hunter immediately after being caught. To prevent this from happening, you can cling to the edge of the cliff while hugging the boundary wall of the initial access. This giant Squid ignores players who violate this rule. However, if ignored, continue to stick to the wall, as the squid will patrol the area frequently.

Conduit Crystals and Depth Module

The main access route is the Depth Module MK1. You can find it among the Needle Nose structures, and once inside, search the bottom to find a migrant's light. You need to go to a depth of more than 200 meters and find its prototype near an empty tadpole nest. This module allows you to dive up to 200 meters and explore the sea floor.

The most difficult resource in the Subnautica 2 guide is known to be conduit crystals. These crystals are located around Alien Roots (large purple structures attached to the Angel's shoulders). Of course, don't forget that these crystals only appear around roots that are 50 meters (or more) deep. Note that scanning is usually worthless and the only surefire way to find them is to visually search the deepest parts of the root. But the good news is that only two or three crystals are needed for the bio-scanner. They can enable most of the end-game equipment, such as alien controls, power plant access, and observatory.

Final Recommendations for Early Access

Final practical advice in the Subnautica 2 guide:

  • Enable manual saving before any dangerous journey.
  • Build an auxiliary secondary base for oxygen storage.
  • Scan everything thoroughly.
  • Your priority should be finding the Depth Module.

Although the current Early Access version is unfinished, it does contain a ton of content. The main obstacles in the game are the Conduit Crystals and the Collector Leviathan Corridor, but keep in mind that a careful reading of the Subnautica 2 guide will help you avoid getting lost in the game. Note that using the Subnautica 2 guide will help you avoid any confusion or frustration about carrying storage on the Tadpole and keeping spare batteries.
