Survival Multitool

The Survival Multitool is Subnautica 2's replacement for the original game's Survival Knife — a single tool that harvests, cuts, and helps you survive the opening hours. Launch-week guides treat it as an early crafted item, not a free starting inventory tool.

Critical warning: As of Update 1 "Adaptive Measures," hitting most creatures makes them recoil or flee, and a Sonic Resonator hit briefly leaves them dizzy — but you still cannot kill them. Use the Multitool to buy an escape, not to win a fight.

Safe uses

What the Multitool is genuinely good at. Stick to these and the early hours are smooth.

Dangerous mistakes to avoid

These are the early pitfalls that filled forums with "the game broke me" threads. All three are preventable.

Threat indicator — when to swing, when to swim

Public guides mention threat states, but the fine details can shift across patches. The safe rule for the Multitool is simple: use it when you need to harvest or cut, not to brawl.

State What it means
Passive Safe to observe and usually safe to harvest around.
Cautious Treat with care. Do not swing first unless the current build makes the interaction obvious.
Hostile Back off. The Multitool is for creating space, not for brawling.

Threat states are read off scanned creatures. Unscanned creatures appear in grey — treat them as yellow until proven otherwise.

How to obtain

  1. Craft it at the Fabricator with Titanium. Public launch guides list the recipe as 3 Titanium.
  2. Once you have it, treat it as the early utility tool for harvesting and cutting.
  3. If later patches add upgrade tiers, verify them in-game before writing the upgrade tree into the wiki.
  4. If the current build changes durability or replacement rules, update this page instead of assuming the launch behavior is permanent.

Upgrade tiers

Launch-week sources confirm the tool and its early Titanium recipe. Beyond that, do not write a fixed upgrade tree into the wiki until the current build confirms it.

Compared to Subnautica 1 Survival Knife

Players coming from the first Subnautica often default to "knife = combat tool" reflexes. The Multitool intentionally pushes against that habit:

Mechanically, the swap still tells the same story: prepare, gather, and leave on your terms.

FAQ

Can I kill creatures with the Multitool?
No. Early Access Update 1 "Adaptive Measures" (July 8, 2026) made most creatures recoil or flee when hit with the Survival Multitool, but Unknown Worlds confirmed creatures still cannot be killed. Use it to create space and escape, not to farm kills.
