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: hitting most creatures with the Multitool can make them recoil or flee. EA 1.2 separately gives the Sonic Resonator a 10-second stun and makes the Feedback Resonator stun instead of trigger flee behavior. Use every tool to buy an escape, not to win a fight.

Tested in the Early Access 1.2 official tool-behavior baseline, August 19 2026. Updated .

Diver with a survival tool underwater, concept-style art (not official Subnautica 2 media).

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. Keep the tool ready for harvesting and use creature recoil as a chance to retreat.
  4. If the current build changes durability or replacement rules, update this page instead of assuming the launch behavior is permanent.

Harvesting and defensive use

The Survival Multitool supports starter harvesting and gives you a way to create space when a creature approaches. Prioritize it alongside the Scanner during the first material loop.

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?
Early Access Update 1 "Adaptive Measures" made most creatures recoil or flee when hit with the Survival Multitool. Use it as a defensive tool to create space and escape.
