Biome Map · Early Access · as of 2026-06-20
Bottom line: the Subnautica 2 Early Access map has 8 biome labels we can track right now - 4 confirmed from official footage or store materials and 4 that are community-sourced or predicted. This page maps each biome to its plotted in-world locations (32 source-tagged points), shallow to deep, so you can see where each zone sits before you dive.

Subnautica 2 is in Early Access, so biome names, boundaries and the final zone count are not locked. We separate every entry by confidence: Confirmed means it appears in official footage or store materials, Community comes from Reddit / Discord / clips, and Predicted is inferred from Subnautica 1 and Below Zero patterns. Predicted and Community zones are search leads to verify in your own save - not launch-build facts.
How To Use
1. Sort by depth
Biomes are listed shallow to deep. Start near the surface zones, then push deeper only as your gear allows.
2. Check the tag
Trust Confirmed zones first. Treat Predicted and Community labels as leads to verify in your own playthrough.
3. Jump to the map
Each biome links to its markers on the interactive map and to the full coordinates atlas.

FAQ
We track 8 public biome labels for the Early Access map: 4 confirmed from official footage or store materials and 4 community-sourced or predicted. The final count is not official while the game is in Early Access.
Yes - this page maps every tracked biome to its 32 plotted in-world locations and pairs each one with a depth band and confidence tag. For the visual version use the interactive map.
No. Predicted and Community zones are inferred from Subnautica 1 / Below Zero patterns or pre-launch claims, not the launch build. Verify them in your own save before planning a route.
