Subnautica 2 Biomods, Bioscans & Adaptations
Track every Subnautica 2 Biomod, the bioscans that unlock it, and the story adaptations tied to Biolab progression.
Install biomods at the Biolab using Genomes earned from scans. Active skills are triggered manually; passive effects stay on; positive traits help you; negative traits are maladaptations with a downside. Positive and negative traits are not all available in the current Early Access build yet. Turn on “Show unavailable” below to browse the full list.

Subnautica 2 Biomods Overview
Subnautica 2 Biomods define how your character handles pressure, heat, traversal hazards, and advanced biome mechanics. This page combines Subnautica 2 Biomod unlock costs, bioscan donors, and adaptation context in one progression view.
By pairing genome rewards with biomod requirements, you can evaluate which Subnautica 2 creature scans unlock the most practical Subnautica 2 Biomod upgrades for your next expedition route.
How the Subnautica 2 Biomod Database Is Organized
The Subnautica 2 Biomod database is split into bioscans, biomods, and story adaptations. Use this structure to move from scan source, to genome budget, to final unlock effect without mixing early-game and late-game goals.
Why Subnautica 2 Biomod Planning Matters
Subnautica 2 genome planning directly affects Biomod efficiency. If you sequence bioscans around Biomod dependencies, you reduce repeat travel, unlock key survivability upgrades earlier, and keep research aligned with actual exploration milestones.
Subnautica 2 Biomods FAQ
Do story adaptations cost genomes like biomods?
No. Story adaptations are progression-based unlocks, while biomods consume genomes in the Biolab.
Can one bioscan unlock multiple biomods?
Yes. Some donor species feed several biomod requirements, which makes scan route planning more important than raw genome farming.
Related Progression References
Bioscans and biomods are easier to plan when you can compare scan targets, genome costs, and the creatures behind each unlock.
Use creatures for habitat and threat context, the Crafting Planner for material needs around the Biolab, and the interactive map to plan scan routes before spending genomes.
