Subnautica 2 Items — Crafting & Resources

A large base-mounted machine that refines raw ores into ingots and synthesizes chemical compounds. The Processor is the turning point of Subnautica 2 progression — without it, advanced tools, vehicles, and base equipment cannot be manufactured. It accepts a queue of up to 15 items and runs asynchronously while you explore.

A highly reactive chemical compound synthesized in the Processor. Strong Acid is a critical mid-game material used in Power Cells, Dedicated Cores, Fiber Mesh, and Scout Ray vehicle construction. It has two crafting paths: the preferred route uses Necrolei Cysts (a renewable biological resource), while the alternative requires Sulfur and Gold — both of which are needed elsewhere.

A solid mass of refined titanium produced exclusively in the Processor. The Titanium Ingot is the first major crafting gate in Subnautica 2 — it cannot be made in the Fabricator and cannot be found in the world. It is required for every advanced tool, all vehicles, and key base machines. Producing your first ingot marks the transition from early survival to mid-game progression.

Used to carefully approach creatures and collect raw alien DNA samples. Step one of the genetic modification pipeline. Approach a creature slowly and activate to extract a sample without startling it.

Constructs all Subnautica 2 base modules, rooms, corridors, and fixtures. Not available from the start — scan two Habitat Builder fragments found in wreckage to unlock the blueprint, then craft it at the Fabricator.

Repairs damaged equipment, vehicles, and base components. Required for maintaining the Tadpole Submersible after leviathan encounters.

View guide →

Essential tool for cataloguing creatures, plants, and resources. Scanning creatures unlocks their data entry and may reveal DNA modification options.

View guide →

A handheld propulsion device for faster swimming. Essential for escaping the Collector Leviathan and covering large distances outside the Tadpole.

Increases maximum oxygen by +30. One of the highest-priority early crafts in Subnautica 2 — extra oxygen dramatically extends dive time and reduces early deaths. Requires Silver Ore.

View guide →

Multi-purpose handheld tool for interaction, harvesting, and basic tasks. Critical warning: striking any creature with this tool causes it to become permanently hostile and actively hunt you. Never use it as a weapon.

A pale crystalline mineral ore found in mid-depth biomes. Celestine is processed into Strontium in the Processor, which is required for the Tadpole Haul Chassis, Feedback Resonator, and the Modification Station build recipe. Two Celestine ore produce one unit of Strontium in 30 seconds.

A rare crystalline resource — arguably the rarest material in the early game. Conduit Crystals grow on rock walls and cliff faces in the region east of the Alien Ruins, often hidden in shadowed areas behind rock structures. Three are required to craft the Bioscanner, which unlocks all non-default Biomods and opens the full DNA Modification progression track.

A hard biological material harvested from tooth clusters found near Needler Mango plants. Creature Enamel is the key ingredient for Enamelled Glass, which is required to craft the Bioscanner — the tool that unlocks all non-default Biomods in the DNA Modification system. Use the Sonic Resonator on the tooth cluster base to harvest it.

A biological cyst harvested from Necrolei formations — large, purple weed-like organisms anchored to the seafloor in deeper biomes. Necrolei Cysts are the primary ingredient for Strong Acid in the Processor, making them an essential mid-game resource for Power Cells, Dedicated Cores, and vehicle construction.

A rare metallic ore found in mid-depth rocky biomes and canyon systems. Silver Ore is used directly in Fabricator recipes (Wiring Kit, Advanced Wiring Kit) and must be refined into Silver Ingots in the Processor for vehicle and advanced base construction. Significantly rarer than Titanium and Copper, making dedicated farming runs essential before mid-game crafting.

A dark metallic sulfide mineral found in deeper volcanic and hydrothermal zones. Troilite is used in several advanced recipes including Mangalloy Ingot (for the Metal Farm automation module), the Tadpole Depth Module Mk.2, the Feedback Resonator, and the Photovoltaic Charger.

The foundational module of any underwater base. Connects to other compartments and provides habitable space. Subnautica 2 uses a procedural building system for greater flexibility.

View guide →

A base module containing a centrifuge and sequencing equipment. Processes raw Biosampler samples into refined genetic serums ready for the Gene Augmentation Station.

View guide →

Allows players to apply genetic material collected from scanned creatures to gain biological upgrades. A new mechanic unique to Subnautica 2.

View guide →

Injects processed genetic serums into the player character, granting passive traits (e.g. pressure resistance, night vision) or active abilities. Part of the DNA modification system unique to Subnautica 2.

Generates power from sunlight for your Subnautica 2 base. Build on the roof of base modules. Effective in shallow water (under 200m), less efficient at night, and non-functional below 200m depth. Best early-game power source.

View guide →

Generates power from geothermal heat. Must be placed near thermal vents in the Thermal Spires biome for maximum efficiency. Provides passive, unlimited power.

View guide →

The primary vehicle in Subnautica 2. A compact, maneuverable submarine for mid-depth exploration. Can be upgraded with additional modules and customized cosmetically.

View guide →

A large alien organism found ~205m northwest of the Lifepod, surrounded by a toxic Bloom Biofilm. When cured using the Sonic Resonator to destroy the surrounding Bloom, interacting with the Angel Comb grants the Heat Tolerance Adaptation — which allows the Pioneer to survive in high-temperature volcanic zones and farm Sulfur. The Angel Comb is a critical story and progression milestone.
