What Is the Repair Tool?
The Repair Tool is a battery-powered handheld device that repairs damaged mechanical objects. The in-game description calls it a "combination scanner and portable fabricator" that uses magnetohydrodynamic manipulation to restore damaged systems. Practically: aim at a damaged object and hold the trigger.
The Repair Tool is a key mid-game progression item — many wreck sections are locked behind broken doors that only it can open, including the large wreck northeast of your Lifepod where the Rebreather blueprint is found.
Step 1: Unlock the Blueprint
Scan 2 Repair Tool fragments scattered across wrecks near your Lifepod. Once both are scanned, the blueprint unlocks automatically in the Fabricator under the Tools category. The three locations below remain useful alternatives.
Fragment 1 — Colonist Bunker
Direction: Southeast of Lifepod (compass ~150–165°)
Depth: ~30m
Find the rock formation and enter via a red hatch below a blue indicator light. The Repair Tool fragment is on a desk inside the bunker.
Fragment 2 — Cicada Wreck (Lander Garage)
Direction: Northeast of Lifepod (compass ~30–60°), ~347m away
Depth: ~30m
Enter from underneath the wreck via the left-side entrance into the lander garage. The fragment is on the ground in the southeastern corner of the garage.
Fragment 3 — Cicada Wreck (Canteen)
Direction: South of Lifepod (compass ~195°), ~270m away
Depth: 50m+
Enter from the back of the wreck, go left and dive down. The fragment is on a couch near a cracked elevator.
Step 2: Craft the Repair Tool
Craft at the Fabricator → Tools category.
| Material | Amount | How to Get |
|---|---|---|
| Titanium Ingot | × 1 | 3× Titanium Ore → Processor |
| Wiring Kit | × 1 | Silver Ore × 1 + Copper Wire × 1 → Fabricator |
| Basic Battery | × 1 | Copper Ore × 2 + Acidic Raion Pouch × 1 → Fabricator |
| Sulfur | × 1 | ~200m SE of Lifepod near Coral Crabs (~25m deep), or hydrothermal zones |
⚠️ Note: Sulfur in hydrothermal zones requires the Heat Tolerance Adaptation to gather safely. Early game, find a small amount ~200m southeast of your Lifepod near the Coral Crabs area at ~25m depth — no Heat Tolerance needed there.
What Can the Repair Tool Fix?
| Target | Effect |
|---|---|
| Tadpole Submarine | Restores durability — at 0% the sub can't move until repaired |
| Broken wreck doors | Opens sealed sections to access blueprints and supplies |
| Alterra wreck components | Restores damaged hull and habitat modules |
Tips
- A HUD prompt appears automatically when a repairable object is within range — no guessing needed.
- Battery drains at 1 energy per second. Carry spare Basic Batteries for long wreck dives.
- Assign the Repair Tool to a toolbelt slot for fast access during exploration.
- Repairing doors in the large northeast wreck unlocks the Rebreather blueprint — a major upgrade for deep diving.
