Add a Bioreactor to your Subnautica Seabase

The Bioreactor converts any biological material into power for your Seabase, providing an endless source of free power as long as someone is around to keep feeding it material occasionally.

The big payoff from venturing out to the Floating Island is that we now have the pieces needed to start farming food in the Seabase. Edible plants also provide a source of H2O, meaning that as long as you’re in…

Now that you’ve reached the Floating Island, it’s time to start exploring it. There a lot to see and do on the island, but this guide will focus on basic goals for your first visit that will enable you to…

Once you’ve acquired the Seamoth, a run to the Floating Island should be your first road trip as it is key to unlocking your ability to farm your own food, which also helps reduce your need to drink bottled water.

This tutorial picks up where the early game tutorial ends – right after acquisition of the Seamoth. Early game was mostly focused on close-range exploration, getting basic tools built and basic survival needs met. Mid-game, enabled by the use of…

The Seamoth submersible vehicle is one of the most game-changing items that can be acquired in Subnautica. It allows the player to quickly reach and return from distant parts of the map, and to explore deep underwater without ever worrying…

Exploring the Grassy Plateaus presents some new challenges because of the depth of the seabed. The Floating Air Pump and Pipes can be very helpful in this early stage of the game where you don’t yet have more convenient options…

Up to this point in the tutorial, everything that’s been covered can be accomplished within a 300 meter radius of your Lifepod. During this early game exploration we’ve come across the first two biomes of Subnautica: The Safe Shallows and…

The Repair Tool and Radiation Suit are two items that I’ve deliberately put off until later in the tutorial, despite being somewhat early-game items in terms of the materials needed in order to fabricate them.

Once you’ve finished crafting your Habitat Builder, you can use it to start building your first Sea Base.

Seabases are constructed, and de-constructed, exclusively with the use of a handheld tool called the Habitat Builder. Compared to other items you’ve built up to this point, the Habitat Builder is fairly expensive and complicated to build, involving multiple layers…

By this point you may have already noticed a couple of kinds resource deposits that haven’t yet been discussed: Salt Deposits and Sandstone Outcrops. These two new types of resource are key to upgrading your H2O supply and O2 tank…

The Seaglide and Grav Trap are two tools that greatly enhance your ability to progress forward, but you won’t have the blueprints for them at the start of the game.

The Handheld Scanner is one of the most essential items in Subnautica as it is required in order to unlock blueprints for other items. Now is also a good time to gather materials for the Flashlight.

At the start of the game, the player is already given access to dozens of blueprints, which can be viewed on the Blueprints tab of the PDA and can be used to fabricate items from resources at the Fabricator. Most…
