Tools & Equipment
Subnautica 2 has no weapons — every item is a survival, collection or utility tool. The Early Access build ships hundreds of item entries; below are the essential, confirmed tools, all crafted at the Fabricator.
Tool (7)
Scanner
The core analysis tool — scans fragments and fauna to unlock blueprints and fill the Data Bank, with an integrated radar hologram.
Survival Multitool
The expanded successor to the survival knife — a multi-function harvesting tool needed for nearly every recipe.
Habitat Builder
Constructs the base itself — compartments, facilities and external structures. No permanent home exists without it.
Air Bladder
An emergency safety tool for rapid ascent — and, new for co-op, it can share oxygen with nearby divers.
Sonic Resonator
An acoustic tool for mining and creature interaction — the only way to clear bloom infection and expel Tongue Thieves.
Repair Tool
A hybrid of a Scanner and a portable Fabricator, used to repair vehicles and bases.
Bioscanner & Biosampling Kit
Biological analysis and organism-collection tools for studying Proteus's fauna and flora.
