Subnautica 2: How to Unlock Blueprints & Crafting Recipes

TL;DR

• The main way to unlock blueprints is by scanning degraded tools and equipment with the Scanner.
• Some blueprints unlock automatically just by picking up a new material for the first time.
• Most blueprints need 2–3 scans of the same item before they fully unlock.
• Interacting with terminals in ruins can also unlock certain recipes.
• Duplicate scans reward you with 1x Titanium instead of wasting your time.
• The Fabricator, Processor, and Habitat Builder each have their own set of unlockable recipes.

In Subnautica 2, your starting crafting menu is almost empty. That is by design. The whole game is built around exploring the ocean, finding abandoned equipment, and slowly unlocking the gear you need to go deeper and survive longer.

But if nobody explains how the blueprint system works, it is easy to miss things. This guide covers every method to unlock blueprints and crafting recipes, what to scan first, and how to make sure you are not leaving progress on the table.

If you have not crafted a Scanner yet, start with our guide on how to craft the Scanner in Subnautica 2. You need it before almost anything else.

How Blueprints Work in Subnautica 2

A blueprint is simply a crafting recipe. Once unlocked, it appears in the relevant crafting station — the Fabricator, the Processor, or the Habitat Builder. You can craft it as many times as you want from that point on.

Blueprints are not handed to you. You earn them by exploring, scanning, and picking things up. The game tracks your progress automatically, so you always know how close you are to finishing a recipe.

There are three main ways to unlock blueprints in Subnautica 2:

• Scanning degraded tools and equipment fragments
• Picking up new materials for the first time
• Interacting with terminals in ruins and outposts

Method 1: Scanning — The Main Way to Unlock Blueprints

Scanning is how you unlock the vast majority of blueprints in Subnautica 2. The ocean floor and every abandoned structure are full of degraded tools and broken colonist equipment. These are not usable as-is, but your Scanner can read them and add their recipes to your database.

Here is how scanning works step by step:

1. Equip the Scanner from your hotbar (slots 1–5).
2. Approach a scannable object. A small icon will appear in your HUD when you are close enough.
3. Point the Scanner at the object and hold right-click to begin scanning.
4. Wait a few seconds for the scan bar to complete.
5. The recipe progress updates automatically in your Blueprints menu.

Once a blueprint fully unlocks, the recipe appears in the correct crafting station. You do not need to do anything extra.

How Many Scans Does Each Blueprint Need?

Most blueprints require more than one scan. Some unlock after a single scan. Others need 2–3 scans of the same item type before the recipe fully registers. When you scan a fragment, a pop-up on the left side of your screen tells you exactly how many more you need. You can also track this in the Blueprints menu.

Do not worry about missing out. The world always has more scan points than you need for any single blueprint. Keep exploring new structures and biomes and you will find enough.

What Happens When You Scan a Duplicate?

If you scan something you have already fully unlocked, the game gives you 1x Titanium instead of wasting the scan. It is a small bonus, but it means scanning is never truly pointless.

Method 2: Picking Up New Materials

Not every blueprint requires the Scanner. Some recipes unlock the moment you pick up a specific material for the first time.

For example, picking up a Pent instantly unlocks the Biofuel Block blueprint. Picking up a Medical Gel Sac unlocks the Fiber Mesh recipe. These triggers happen automatically — no scanning needed.

The best habit to build early: pick up at least one of everything you see. Even if your inventory is getting full, holding a new material for a second may be enough to trigger a recipe unlock. You can drop it back on the ocean floor right after the notification appears.

Method 3: Terminals in Ruins and Outposts

Some blueprints are tied to specific terminals inside colonist ruins and abandoned outposts. Walking up to these terminals and interacting with them unlocks the associated recipe directly. You do not need the Scanner for these.

Keep an eye out for interactive terminals whenever you explore a new structure. They are easy to miss if you rush through a location.

Where to Find Things to Scan

The world of Subnautica 2 is full of abandoned equipment from colonists who arrived before you. Here is where to look:

• Underwater wrecks and crashed landers — These are the richest sources of scannable fragments. Tools, equipment, and vehicle parts are scattered all through them.
• Colonist outposts and ruins — Camps like Camp One contain furniture, broken equipment, and terminals with unlock triggers.
• Caves and coral formations — Smaller fragments and organic materials often hide in tight spaces that look easy to skip past.
• Open seabed between structures — Some fragments are partially buried or drifting loose. Scanning regularly while you swim pays off.

Even a quick pass through a cave or ruin to scan available items is worth the stop. You rarely need to fully clear a location to get value from it.

What to Scan First — Early Priority Blueprints

Not all blueprints are equally important. Some unlock things you need immediately. Others are nice later but not urgent. Here are the ones you should prioritise early:

Flashlight

Caves and deep water are dark. The Flashlight is one of the first quality-of-life tools you should unlock. Check our guide on how to get the Flashlight blueprint in Subnautica 2 for exact locations.

Habitat Builder

The Habitat Builder unlocks base building. Without it, you are stuck using the limited Lifepod Fabricator. Unlocking the Habitat Builder also automatically unlocks the Window blueprint as a bonus. This is one of the most important early scans in the game.

High Capacity Air Tank

More oxygen means more time underwater. More time underwater means faster exploration and more scans per dive. Get this one as early as possible.

Rebreather

Once you go below a certain depth, you lose oxygen much faster. The Rebreather removes that penalty. A Rebreather can be found inside the Cicada Wreck — Lander Garage northeast of your Lifepod.

Solar Panel

The moment you start building a base, you need power. Solar Panels are the easiest early power source. They work reliably in shallow water and need almost no maintenance. Unlock this early so it is ready when you need it.

The Fabricator, Processor, and Habitat Builder — Which Blueprints Go Where?

Subnautica 2 has three main crafting stations. Blueprints unlock in the correct station automatically, but it helps to know what each one does:

• Fabricator — Your main crafting station. Tools, batteries, food, water, medical items, and most survival gear are made here. You start with one inside your Lifepod.
• Processor — Turns raw materials into refined goods like ingots. Also offers some alternative recipes for items like water. One can be found inside the Cicada Wreck — Lander Garage northeast of the Lifepod.
• Habitat Builder — Used for constructing base modules, walls, storage, power sources, and furniture. You need to unlock and craft this tool first before you can build anything.

When a new recipe unlocks, check all three stations. Some blueprints you expect to find in the Fabricator will actually appear in the Processor instead.

Scanning Creatures and Plants — Does It Unlock Recipes?

Scanning fauna and flora does not unlock crafting recipes. Instead, it adds entries to your Databank (press Tab to open it). These entries contain lore, behavioral notes, habitat information, and sometimes hints about where to find useful materials.

It is worth doing, especially early on when the ocean is completely unfamiliar. But if your immediate goal is unlocking gear, prioritise scanning degraded tools and colonist equipment over wildlife.

Tracking Your Blueprint Progress

You can see every blueprint you have partially or fully unlocked in the Blueprints menu. For partially unlocked blueprints, the menu shows your current scan count and how many more you need.

Use this to plan your dives. If you need two more scans of a specific tool, you know to look for it on your next exploration run rather than scanning randomly and hoping.

Tips to Unlock Blueprints Faster

• Always have the Scanner on your hotbar. It should be slot 1 or 2, always accessible.
• Never skip a new structure. Even a small ruin might have the fragment you need.
• Pick up everything new. Material-triggered blueprints cost you nothing — just grab it and drop it if you do not need it.
• Check multiple biomes. Many fragments appear in more than one location across different areas. If you cannot find enough in one zone, move to the next.
• Do not rush past decorative items. Even furniture and aesthetic objects sometimes unlock useful base-building options.
