Subnautica 2 ships 81 biomod entries in its May 14, 2026 Early Access build, replacing the fragment-and-blueprint upgrade chain of the original Subnautica with a player-character ability system. Biomods are bio-engineered abilities you equip directly on the Pioneer, drawn from a research tree gated behind Adaptation Points you earn by scanning new biomes, fauna and architecture.
There are two slot types. Active biomods occupy a hotbar slot and fire on input. Dash is the hero example: hold a direction, hit the bind, and you burst out of a predator's lunge cone with a short cooldown. Passive biomods live in a separate panel and apply continuously: faster swim speed, longer oxygen pool, less damage from acid blooms, broader scanner radius. The two panels never compete for slots.
Unknown Worlds has stated that biomod count, naming and unlock costs will continue to evolve through Early Access. The wiki re-imports straight from the live build each patch, so the database above is always exactly what ships with the current game.
