Subnautica 2 All Resources List

The seabed in Subnautica 2 is packed with materials, but the game does almost nothing to point you toward them. You can spend an entire session swimming in circles wondering why you can't craft that next piece of equipment, only to realize the resource you need has been sitting on a cave ceiling the whole time. This guide covers every resource currently available, broken down by category, with notes on what each one actually builds.

What are the resource categories in Subnautica 2?

Resources split into three groups: Inorganic Resources (minerals and ores you mine from the environment), Flora and Fauna (organic materials harvested from plants and creatures), and Salvage (wreckage and debris found in the world). A small handful of items exist in the current build but have no crafting recipe attached yet.

Knowing which category a resource belongs to tells you where to look. Inorganic materials are mostly on cave walls and the ocean floor. Flora and fauna resources come from specific plants and sea creatures. Salvage turns up near wrecks and debris fields.

Inorganic Resources

These are the backbone of most equipment recipes. Titanium, Copper, and Quartz come from Raw Ore nodes, so finding Raw Ore deposits is your fastest path to all three at once. Raw Ore processes into Copper, Quartz, and Titanium at the Fabricator.

Titanium ores appear as rock-like structures scattered across the ocean bed near the surface. Copper grows along the walls and ceilings of underwater caves. Quartz sits inside the large orange coral formations on the ocean floor, which are easiest to spot at night when they glow. For a dedicated location guide, check out where to find Quartz in Subnautica 2.

Flora and Fauna

Organic resources come from the living parts of the ocean. Some you harvest directly from plants, others drop from creatures or their byproducts. Fibrous Pulp is arguably the most useful flora resource in the early game, feeding into Alcohol, Biofuel Block, Fiber, Water, and several food recipes. Lucifer Rotsac is the orange glowing organism you'll spot along the ocean floor, and it's the only source of Rubber in the game. You craft Rubber at the Fabricator using 2 Lucifer Rotsac.

Medical Gel Sac feeds directly into First Aid and Enhanced First Aid Kit recipes, so keeping a supply on hand matters for longer dives. Acidic Raion Pouch is your source for Basic Battery and Mild Acid, two things you'll need early and often.

Several flora and fauna items, including Aeroshell Sponge, Cooked Pneuma, Pneuma, and Quadrate, appear in the build but currently have no downstream crafting recipe attached to them.

Managing what you eat and drink while farming these materials is its own challenge. The Subnautica 2 food, water, and digestion survival guide covers how to handle hunger, thirst, and Digestive Incompatibility so you can stay underwater longer without dying to your own stomach.

Salvage: what it is and what it builds

Salvage is the smallest category and currently contains three entries. Metal Salvage processes into Salvaged Titanium at the Fabricator, making it a secondary source of Titanium for when direct ore deposits run thin. Axum Resonator and Biobed Capsule are listed in the current build but have no crafting recipe attached yet.

Resources with no current crafting use

The following items exist in the game right now but don't feed into any recipe. They may be placeholders for content still being developed:

• Algae Block
• Axum Etching Acid
• Houndgar
• Oxygen Bottle
• Sandspear
• Shiver Leviathan

Hold onto these rather than discarding them. Given that Subnautica 2 is in active development, recipes for these materials could arrive in a future patch.

How do you unlock crafting recipes for new resources?

Finding a resource is only half the job. You also need the corresponding recipe before the Fabricator will let you build anything with it. Scanning items in the world is how most blueprints unlock. The Subnautica 2 scanner guide covering how to scan items and unlock recipes walks through crafting the Scanner and getting the most out of it.

For tools that use these resources as components, the complete Subnautica 2 tool crafting guide lists every tool, what it does, and exactly what materials you need to build it at the Fabricator.

The resources worth prioritizing first

Not all materials are equal in the early hours. Based on the crafting tables above, these are the ones that feed the most recipes and should be your first targets:

• Raw Ore (yields Titanium, Copper, and Quartz from a single node type)
• Fibrous Pulp (feeds food, water, and key equipment recipes)
• Acidic Raion Pouch (your main early battery source)
• Salt (required for food preservation, Power Cell, and Power Storage)
• Lucifer Rotsac (the only path to Rubber, which gates several tools)
• Sulfur (feeds Repair Tool and Advanced Wiring Kit)

Getting these six resources sorted early puts you in a strong position for both survival and base building. Speaking of which, if you're ready to set up a permanent base, the Subnautica 2 base oxygen and power guide covers the Habitat Builder, power sources, and storage, all of which depend on the resources listed here.
