For resource runs
Open the resource map after choosing an area. Resource pages sort candidates from the Lifepod and show notes for route planning.
Biomes
Subnautica 2 biomes and resource areas
A spoiler-light biome tracker for Early Access route planning. Use area labels, resources, depth range, and confidence levels to decide which route is practical before opening a full interactive map.
Once you have picked a candidate area, drop your current XYZ and the area's depth into the coordinates calculator to see horizontal distance, bearing, and depth change before you commit to the route.
Area candidates

| Early Game Region | Silver | -35m | C3 |
| High-Temperature Biome Edge | Gold | -45m | C3 |
| Hot Cave Basecamp | Lithium | -180m | C3 |
| Northeast Ravine | Lead | -65m | C3 |
| Open Seabed Pillar | Sulfur | -25m | C4 |
| Starting Region Caves | Copper, Silver | -45m to -30m | C3 |
| The Great Jaw | Lithium | -105m | C4 |
| The Great Jaw Approach | Lithium | -95m | C3 |
| Underwater Cave | Copper | -23.03m | C4 |
| Volcanic Vent Region | Gold | -36m | C4 |
| Warm Graveyard Edge | Sulfur | -90m | C3 |
For base planning
Treat area labels as a first pass. Base-location pages should wait until resources, depth, and danger zones have better current-build evidence.
For spoilers
This page avoids story details and only uses creature or hazard notes when they change navigation safety.
For coordinate planning
Paste your current XYZ and the area depth into the coordinates calculator to compute horizontal distance, bearing, and depth change before committing to a long route.
FAQ
Are these official Subnautica 2 biome names?
No. This page uses candidate area and biome labels from the current resource dataset. Labels may be renamed as official terminology and better current-build evidence arrives.
Which biome should I visit first?
Start with the area that has the resource you need, the shallowest practical depth, and the highest confidence label. The nearest horizontal coordinate is not always the safest route.
How do biome pages connect to the map?
Biome rows link resource intent, depth, and route planning. Use them with the homepage Navigator when you know your current raw XYZ position, or drop a candidate area depth into the coordinates calculator to compare horizontal distance, bearing, and depth change against your own position before you commit to a route.
