Subnautica 2 Repair Tool — Fragment Locations & Recipe

Subnautica 2 — current release build

Overview

A battery-powered combination scanner and portable fabricator. The Repair Tool analyses damaged systems, breaks up the damaged area using a high-temperature arc, and uses magnetohydrodynamic manipulation to guide liberated material for fabricated repairs. Use it to fix Tadpole hull damage after crush depth warnings, patch base hull breaches, and bypass locked control panels inside wrecks.

Fragment Locations — Unlock Blueprint

Scan 3 of these fragments to unlock the crafting blueprint. The first location is found naturally during the main story quest.

1. Chap's Base (Southeast Cave)

Easiest
Distance~220m southeast of Lifepod
Heading~150–165° SE
Depth30–40m

Landmark: A tall stone pillar with a ring-shaped cave entrance glowing with blue light at its base. Drop inside and enter the abandoned habitat hatch.

Fragment is on a desk inside. This location is visited naturally during the main story quest (retrieving Chap's black box via NOA) — easiest fragment to find.

2. Southern Shipwreck

Distance~270–300m south of Lifepod
Heading~195° south
Depth30–50m

Landmark: Large metal shipwreck near tall rocky cliffs. Enter through the small door on the south side, follow the cracked elevator shaft to the lower level.

Fragment sits on a sofa in the corner of the lower level.

3. Northeast Shipwreck

Distance~380m northeast of Lifepod
Heading~60° NE
Depth50m+ (bring extra O₂)

Landmark: Large wrecked structure. Dive beneath the hull, enter through the big half-open door into the storage hangar, proceed to the room with a window.

Fragment is near a locked door by a couch. BONUS: Use the crafted Repair Tool on the locked control panel here to unlock a sealed room containing the Rebreather blueprint. Also has Processor, Tadpole, and Bioreactor scan targets.

Titanium Ingot×1
Wiring Kit×1Craft at Fabricator: 1× Silver Ore + 1× Copper Wire
Basic Battery×1Craft at Fabricator: 2× Copper Ore + 1× Acidic Raion Pouch

⚠ Important Notes

  • Must be crafted at a Fully Functional Base Fabricator — the damaged Fabricator in your starting Lifepod cannot make this item.
  • Sulfur is the gating material. Two small pieces can be found near Chap's Blackbox (~220m SE) without needing Heat Tolerance — enough for one Repair Tool.
  • Large Sulfur deposits require the Heat Tolerance Adaptation (from scanning the Angel Comb, ~205m NW of Lifepod).

Tips

  • Equip to the toolbelt quick-access slot. Aim at a damaged object and hold the trigger — the HUD automatically highlights repairable targets.
  • A single Basic Battery lasts through multiple repair jobs under typical use.
  • The northeast wreck is 50m+ deep — bring extra O₂ tanks before your first visit.
  • After crafting, return to the northeast wreck and use the Repair Tool on the control panel to unlock the sealed room with the Rebreather blueprint.
  • The HUD shows a "Warning: Crush Depth. Hull Damage Imminent" alert when your Tadpole exceeds its depth limit (~250m stock). Surface and use the Repair Tool on the hull to restore integrity.
Recipes, quantities, and locations may change with updates. Data reflects the current May 2026 release build.
