Biome Database
Subnautica 2 Biomes
8 biome labels tracked for Early Access - depth bands, threats and resources are separated by confidence so you know what is official, community-sourced or predicted.
Resource Routes
Looking for Silver, Strong Acid, Necrolei Cyst, Titanium Ingot, Creature Enamel or Celestine? Use the dedicated resource guide before treating a biome label as a precise spawn guarantee. Launch-week route sources are changing faster than biome names.
