Surviving the alien ocean in Subnautica 2 comes down to one thing early on: knowing which materials matter and where to grab them without wasting oxygen. Five resources do the heavy lifting through the opening hours, powering your first fabricator, oxygen tank, base pieces, and tool upgrades.
Why these five resources matter
Every early crafting recipe leans on this group. Titanium frames your base and most tools. Copper wires power systems and batteries. Quartz becomes glass for tanks and habitat windows. Silver feeds wiring kits and advanced electronics. Lead shields you from radiation and locks down reinforced builds.
Two of them, Titanium and Lead, scale up dramatically once you unlock the Sonic Resonator, which cracks open the larger ore nodes scattered across the seafloor.
| Resource | Primary use | Tool needed |
|---|---|---|
| Titanium | Base panels, tools, fabricator recipes | None (Sonic Resonator for big nodes) |
| Copper | Batteries, wiring, power systems | None |
| Quartz | Glass, windows, oxygen tanks | None |
| Silver | Wiring kits, advanced electronics | None |
| Lead | Radiation shielding, reinforced parts | None for small chunks; Sonic Resonator for crystals |
Titanium: The everywhere metal
Titanium is the most common find in the game. Small dark gray rocks sit on the seafloor across nearly every biome, and you can pick them up by hand without any tools. Larger deposits show up inside cave systems, where a single break can yield multiple chunks.
The best early farming run sits roughly 90 meters east of the Lifepod, near the Angel Comb tied to the main story. Follow the "Anita - Black Box" signal, then look for wreckage flanked by glowing Mimic Pylons. A small cave opening to the right of the wreckage pulls you down via a current into an extensive cave network with oxygen plants and air pockets. Copper deposits line the same caves, so you rarely leave empty-handed.
Metal Salvage scattered near wreckage and outposts is the other steady supply. Haul those chunks back to a Fabricator to convert them into Titanium.
Copper: Caves only, but close to home
Copper does not appear on the open seafloor. It grows inside underwater caves, usually on the ceiling, so look up while you swim. You don't need a tool to harvest it.
Two farming spots cover the early game. The first sits directly beneath the Lifepod through a small circular hole in the seafloor, leading to a cave with an oxygen plant and Copper along the walls. The second lies about 50 meters east of the Lifepod, where a larger cave system holds denser deposits. A natural upward current blocks the front entrance, but you can slip in through crevices around the side.
Past that cave, the floor drops into deeper water with much bigger Copper nodes. Those require the Sonic Resonator before they break.
Quartz: Coral Domes in the shallows
Quartz forms underneath Coral Domes, the bright orange formations with blue-green spots scattered across the starting biome. Swim under one and look up to spot the crystals. Most domes yield a few pieces, and some have air pockets inside that double as emergency breathers.
The shallows around the Lifepod are dense with Coral Domes, making this the easiest resource to stockpile. Domes do respawn over time, but if you need a large batch quickly, swim further out to fresh formations.
Silver: Deeper caves toward the Old Habitat
Silver never spawns in the shallow biome. It appears at depths of 30 meters or more, typically clinging to cave walls and ceilings. It looks similar to Titanium, so it's easy to swim past on a first pass.
The fastest farming run heads north from the Lifepod. About 200 meters out, look for an overhang with purple Jelly Lei hanging over a small entrance leading straight down. The cave below is packed with Silver despite being close to spawn. Bring Distraction Flares because predators patrol the area.
A second farming spot sits right next to the Old Habitat, roughly 400 meters north. To the right of the habitat, a large cave entrance opens up. Follow the glowing green plants downward into a chamber lit by bright blue bulbs, where Silver nodes dot the walls and ceiling. The nodes barely poke out, so swim slowly.
Lead: The Cicada Wreck run
Lead concentrates around the Cicada Wreck, also called the Lander Garage, roughly 400 meters northeast of the Lifepod. That's a long swim for a new player, and the route is guarded by hostile predators. Bring Distraction Flares and craft Basic Fins plus a Wakemaker before attempting it.
Lead shows up as purple blocky stones. Small pieces along the seafloor can be picked up by hand. The larger crystals scattered around the wreck require a Sonic Resonator to break open, so plan a return trip once you've crafted one.
Lead continues to spawn deeper into the surrounding biome, with the 400-meter mark acting as a rough cutoff. If a spot has been picked clean, push further from the Lifepod to find fresh deposits.
Order of operations for early farming
If you're starting fresh, this sequence minimizes backtracking and oxygen pressure.
Step 1: Grab Quartz and Titanium right next to the Lifepod. Crack open a few Coral Domes for Quartz, then sweep the seafloor for loose Titanium chunks. This gets you a Fabricator and basic tools.
Step 2: Dip into the caves directly below and 50 meters east of the Lifepod for Copper. Pair that with any Titanium you spot on cave walls.
Step 3: Head north toward the Old Habitat for Silver. Stop at the 200-meter Jelly Lei cave first, then push to the Old Habitat cave once you have better gear.
Step 4: Make the Cicada Wreck run for Lead. Pack Distraction Flares and equip Basic Fins plus a Wakemaker before leaving base.
Step 5: Return with a Sonic Resonator. Larger Titanium, Copper, and Lead nodes you swam past earlier become available, which dramatically speeds up mid-game stockpiling.
Stick to this loop and the early hours stop feeling like a guessing game. Once you've unlocked the Sonic Resonator and a few mobility upgrades, the same biomes that felt punishing in your first dive become reliable farming routes you can clear in a single oxygen cycle.
