Do not farm by danger rating
High danger does not mean high material return. The Sparse Plains are intentionally sparse, while Kelp Forest and Graveyard runs can be more efficient for ordinary progression.
Biome batch 1 | Updated 2026-05-15
Subnautica 2 Biomes
Batch 1 covers the four biome pages most useful for early survival routing: Kelp Forest, Jelly Plateaus, Graveyard, and Sparse Plains. Each page now focuses on route order, scan value, resource expectations, base viability, and the hazards that actually change player decisions.
Recommended order. Stabilize in Kelp Forest, practice mid-depth routes in Jelly Plateaus, run planned salvage in Graveyard, and avoid Sparse Plains until the Tadpole and Collector escape plan are ready.
Starter Danger 1 / 5 Shallow
Kelp Forest
Spawn perimeter, first scans, Angel Comb route, and first base.
Mid-depth Danger 2 / 5 Transition
Jelly Plateaus
Low-danger shelf route, glowing flora scans, and early base relocation candidate.
Wreck field Danger 3 / 5 Shallow to mid
Graveyard
Alien wreckage, skeletal remains, dense scans, salvage, and navigation hazards.
Apex zone Danger 5 / 5 Outer map
Sparse Plains
Collector Leviathan territory. Extreme danger, sparse resources, edge scouting only.
Route order
Use this as the spoiler-light sequence for early biome progression.
| Timing | Biome | Goal |
|---|---|---|
| First save | Kelp Forest | Cure Digestive Incompatibility, scan passive fauna, build one compact base. |
| Session two | Jelly Plateaus | Practice mid-depth route discipline and mark a better base shelf. |
| Stable kit | Graveyard | Run focused scan-and-salvage routes through wreckage and skeletal remains. |
| Vehicle ready | Sparse Plains edge | Scout only with a Tadpole, beaconed exit, and a clear reason to enter. |
Use edges as routes
The best biome runs start from boundaries: Kelp edge to Plateaus, Plateaus shelf to Graveyard, known boundary to Sparse Plains scouting.
Beacon before curiosity
Every biome after the Kelp Forest can hide the return path. Place the marker before the scan, not after you are already lost.
Scan-and-salvage routes
The Graveyard rewards focused entries, not full clears.
Extreme danger
The Collector turns open water into a liability.
