Subnautica 2 Biomods: Complete Unlock Guide

Biomods are genetic enhancements equipped at a Bio Lab. You get 1 Active + 1 Passive slot. Active Biomods are manually triggered (Dash, Pathfinder, Sonic Echo, Electric Discharge, Chum Cloud). Passive Biomods are always-on (Oxygen Control, Sea Skimmer, Camouflage, Water Retention, etc.). Unlock new Biomods by crafting the Bioscanner and re-scanning creatures.
