In Subnautica 2, you won’t survive long without a repair tool—the Cicada’s hull will quickly become a sieve, and equipment will start failing at the most inopportune moments. The good news: the blueprint unlocks fairly early if you know where to look. The bad news: simply finding a working one won’t work. The developers have taken a different approach: scan the broken fragments and craft them yourself. Fair enough, considering how many years these pieces of junk have been lying on the seabed.
To obtain the coveted recipe, you need to scan three fragments. There are quite a few scattered across the map, including deep-sea locations in the late game. But three spots are enough to get you started—they’re all just a stone’s throw from the escape pod. Below is a list of the most accessible spots, plus a couple more for later.

Where to find repair tool fragments in Subnautica 2?
A quick route to finding the first three blueprints
Let’s start with the three easiest options. You can find them even before the oxygen in your base tank runs out:
-
The Cicada Canteen is a wreck 280 meters south of the escape pod. Swim inside and scan it. There are often some useful little items lying around there.
-
The Colonists’ Bunker is hidden 250 meters southeast of the pod. If you head northeast for another 120 meters from the canteen, you’ll run right into it. It’s a bit dark inside, but the fragment is visible.
-
The Large Coral Dome is another 140 meters in the same southeast direction. The depth is 94 meters, making it 360 meters from the escape pod. The dome is hard to miss—it’s huge. The fragment is right on the bottom.
This route (canteen → bunker → dome) can be completed in one swim if you don’t get distracted by the fish. And yes, a rebreather will definitely come in handy there—the depth is no joke.
And here are a couple more places that will come in handy a little later, when more biomes open up:
-
Cicada Garage—another wreckage, 600 meters northeast of the capsule. It’s spacious inside, but a bit tricky to navigate—a fragment might fall behind a container.
-
Tadpole Pens—a location with predatory creatures, so be careful. The repair tool is lying right by the entrance.
-
Near Angel Crest—under the power plant. This is closer to the midgame, and you’ll also collect some titanium and silver there.
While you’re crawling around these spots, don’t be lazy and scan everything. The same Cicada wreckage also contains fragments of a rebreather, a base builder, a biobed, a processor, and a bunch of other useful items. The repair tool is just the beginning.
List of resources for crafting a repair tool
With the blueprint in hand, it’s time to head to the Fabricator. And then an interesting detail comes to light: the repair tool in Subnautica 2 requires some rather unobvious resources. Some even have to be refined first before being used. Here’s the full list.
Where to get sulfur and titanium for crafting a tool
-
Titanium ingot (1 piece). Mine 6 pieces of raw titanium, run to the industrial Recycler at the base, and you’ll get an ingot. You can’t do without it.
-
Wire kit (1 piece). Crafted right there at the Fabricator. You need: 1 piece of silver and 1 copper wire. A small thing, but nice.
-
Regular battery (1 piece). A classic: 2 copper pieces plus 1 acidogenic rayon. The latter is obtained from purple plants that the locals call “brains” (and they really do look like them). They grow in several biomes, so you shouldn’t have any problems.
-
Sulfur (1 unit). Now this is something serious. You’ll only find sulfur in the extremely hot zone—east of the escape pod. And yes, you shouldn’t go there without heat adaptation. The expedition will turn into a one-way trip if you’re not prepared.
How to build an industrial Resource Recycler?
The Recycler is a useful thing. It not only makes titanium ingots, but also smelts other resources. You can build it early on; you’ll get the blueprint as part of the story. Place it at your base, load the raw materials, and wait a few seconds. It’s easy.
Incidentally, the tool itself runs on a Regular Battery. When it runs out, you can either insert a new one or recharge the old one—you’ll need a Battery Terminal for that (the blueprint will unlock a little later). But there’s no need to rush: the tool is quite energy-efficient. One battery lasts a long time, especially during the first hours of play, while you’re just getting used to the game and patching up the holes in the Cicada.
What does the repair tool fix and how do you open airlocks?
This thing doesn’t work on every broken piece of metal in the ocean. The list of targets is strictly limited, and a couple of them are sure to be a revelation. At the start of a survival game, the device’s main target is predictably the Tadpole. The local aggressive fauna and occasional encounters with the reefs quickly wear away the submarine’s hull. Reach zero? The engine stalls completely, leaving you no chance of making it back to base. The repair process is straightforward: hover the cursor over the hull, hold down the button, and watch the gauge fill. Theoretically, a wrecked vehicle can always be salvaged for resources. But wasting precious materials on crafting a new boat is sheer madness when it’s much cheaper to burn through a little battery power.
Restoring Base Durability and Sealing
Deep sea pressure isn’t kind to your station’s modules (especially if you’ve forgotten about fortifications). The operating principle here is identical to repairing a vehicle: press and hold. Without a tool in your inventory, you’ll have to engage in the construction drudgery of demolishing the damaged compartment and rebuilding it. Naturally, some resources are irrevocably lost in this scenario.
How to open jammed doors in the Cicada wreckage?
For some reason, many guide makers remain silent about the mechanics. The repair tool is excellent for opening jammed airlocks inside sunken ships. Technically, we repair the sparking control panel on the side rather than breaking down the door itself. A perfect example is the northeastern hangar of the Cicada, which you probably passed while scanning the third fragment. Be sure to break this lock immediately after crafting the device. The critical rebreather blueprint is hidden behind the doors.
Activating broken terminals and obtaining schematics
The seabed is literally littered with broken equipment. We’re talking about various consoles and mechanisms on abandoned research outposts. The catch is that these pieces of iron completely block access to story logs and rare schematics. Without a tool, you’re stuck.
Notice a pattern? There are no workarounds for the last two items. That’s why, closer to the middle of the game, when you start actively vacuuming Precursor complexes and deep-sea stations, the Repair Tool transforms from a useful toy into an absolutely indispensable piece of equipment.
