Finding the right resources at the right time is one of Subnautica’s core gameplay challenges. The game never tells you where anything is — you discover resources through exploration, accident, and the gradual understanding of each biome’s ecological profile. This guide maps out where to find the most commonly needed resources in Subnautica without spoiling the exploration discovery for each biome. Think of it as a spoiler-light reference to consult when you genuinely cannot find something you need.
How Resources Are Distributed
Subnautica uses a biome-based resource distribution system. Different minerals, plants, and organic materials are concentrated in specific biomes. This is intentional — it encourages you to explore new areas rather than farming one location indefinitely. Most resources are found on the ocean floor, inside cave systems within biomes, or in specific rock formations that require a drill (Prawn Suit) to access.
Essential Early Resources and Where to Find Them
| Resource | Where to Find | What It’s For |
|---|---|---|
| Titanium | Everywhere — limestone outcrops, scrap metal | Base construction, most basic crafting |
| Quartz | Sand plains, Grassy Plateau, Mountains | Glass, Enameled Glass for vehicle building |
| Copper | Limestone outcrops, Underwater Islands | Electronics, wiring, most mid-tier crafting |
| Gold | Crash Zone, Sparse Reef, Underwater Islands | Advanced electronics, computer components |
| Lithium | Mountains, Underwater Islands, deep biomes | Plasteel Ingots for vehicle and suit building |
| Magnetite | Mushroom Forest, Mountains (caves) | Vehicle and sonar upgrades |
| Uraninite Crystal | Mountains, Blood Kelp Zone, LRZ | Nuclear reactor, Cyclops nuclear upgrades |
| Kyanite | Inactive Lava Zone | Prawn Suit upgrades, endgame crafting |
| Ion Crystals | Primary Containment Facility area | Alien technology and specific late-game items |
Organic Resources and Where to Farm Them
Organic resources — used for Bioreactors, food, and specific crafting recipes — are biome-specific. The best Bioreactor fuel plants (Marblemelon, Chinese Potato) are found in the Bulb Zone and Underwater Islands. The most nutritious food fish (Peepers, Boomerang) are abundant in the Safe Shallows and Grassy Plateau. Alien Fern Palm samples (used in specific recipes) are found near alien architecture sites.
Using the Scanner Room for Resource Finding
Once you build a Scanner Room as part of your base, resource finding becomes dramatically easier. The Scanner Room scans a radius around your base and maps the location of specific resources you can filter for. Upgrading the Scanner Room’s range and speed makes it one of the most useful tools in the game for eliminating resource hunt frustration. When you need a specific material and cannot find it through exploration, position a temporary base in the target biome, set up a Scanner Room, and let it find the resource for you.
RicardoPlays Resource Tips
Ricardo’s Subnautica series on RicardoPlays includes commentary on resource finding throughout the playthrough — where specific materials were found, which biomes proved most productive, and how the Scanner Room changed his resource gathering strategy in the mid-game. The channel is a practical reference for resource strategies alongside this written guide.
