11Adaptations are permanent DNA upgrades in Subnautica 2, shown in the PDA in a dedicated Adaptations panel. The player draws genetic data from the colored bulbs of Angel Comb growths and applies it to their own body to survive environments that would otherwise damage or kill an unmodified human. Each bulb grants one Adaptation and is consumed on use, and once taken, an Adaptation enters the player's genome permanently. Adaptations gate major progression, which makes them one of the central systems in the game.22Adaptations Versus BioMods44Adaptations are a separate system from BioMods, and the difference is permanence. An Adaptation comes from an Angel Comb bulb, is consumed when claimed, and is locked into the genome forever; it cannot be removed or swapped. A BioMod, by contrast, is a temporary, reversible perk built from creature DNA and managed at a Bio Lab base module, and it never enters the genome. Community materials from before launch sometimes used the word bio-mods loosely for both, but in the current Early Access build they are distinct systems with different sources and different interfaces.66PropertyAdaptationsBioModsPermanencePermanent; enter the genome and cannot be undone.Temporary and reversible; equipped and removed at will.SourceColored bulbs of Angel Comb growths, consumed on use.Creature DNA collected with the Biosampler, processed at a Bio Lab.RoleGate major progression, such as deeper diving and passing the heat barrier.Optional perks for mobility, defense, and resource management.88How It Works99Adaptations are tied to Angel Comb growths placed around Proteus's biomes. Each Comb carries colored bulbs, and interacting with a bulb grants the Adaptation linked to it. The bulb is consumed in the process, so the upgrade is a one-time pickup rather than a renewable resource. Acquired Adaptations are recorded in the PDA's Adaptations panel, which also tracks which ones are still pending.1212The system sits alongside the Biosampler loop, the handheld tool used to study the moon's creatures. The official framing puts genetic change at the heart of survival: the planet is presented as too dangerous for unmodified human biology, so adapting the body is a matter of survival rather than optional enhancement. Crucially, Adaptations modify the player character, not the creatures themselves. The player is the one who changes, borrowing traits from Proteus's native life to better survive the planet's conditions.1414Confirmed Adaptations1616A small set of Adaptations is confirmed in the current Early Access build. Each is acquired from an Angel Comb bulb, and the PDA gates progression in the environments tied to each one. Three representative examples are Heat Tolerance, Pressure Tolerance, and Axum Vision; the full list is not fully documented, so additional Adaptations beyond these are likely and the set should be treated as incomplete.1818AdaptationEffectSourcePressure ToleranceAllows the body to withstand deeper water pressure and dive further than an unmodified human, acquired first during the opening descent.Acquired during the opening sequence, before the player escapes the sinking ship.DigestionAllows the player to eat local fish and plants without taking health damage. Required before cooked food restores hunger safely at the Fabricator.Acquired from an Angel Comb a short distance from the starting Lifepod.Axum VisionAllows the player to read Axum glyphs and inscriptions, unlocking lore-dense underwater structures.Acquired from an Angel Comb far to the east, well past the alien ruins.Heat ToleranceAllows the player to pass the heat barrier and survive the superheated water of hot zones, opening access to areas like the Graveyard and the Tadpole Pens.Acquired from an Angel Comb in a hot biome.2020The Adaptations interface tracks acquired and pending Adaptations, and Unknown Worlds has indicated that a later update will expand the passive Adaptation options available to the player. See Early Access and Development Roadmap for the roadmap items affecting this system.2121Acquiring the Adaptations2323Some Angel Combs can be used directly, while others are sealed and must be cleared first. The Pressure Tolerance and Digestion Combs are reached and used without obstacle. Others, including the Comb tied to Heat Tolerance, appear to be blocked by growths along the Comb's tendrils that have to be destroyed before the central bulb can be reached.2525The Comb that holds Axum Vision sits far to the east, well past the alien ruins, and the long swim out, through leviathan-class organisms, effectively requires a Tadpole. Because the most useful Adaptations sit behind progression gates, gaining them tends to mark turning points in a playthrough rather than minor pickups.2727Adaptations Beyond the Confirmed Set2929Beyond the examples above, Unknown Worlds Entertainment has not published a complete list of Adaptations, so the full roster is not yet documented. Additional Adaptations and additional passive slots are planned for a later Early Access update. Until those ship and are confirmed in the build, this page lists only the Adaptations that are confirmed; speculative entries are deliberately left off, and this section will be updated as new Adaptations are confirmed.3131Connection to the Biosampler3333The Biosampler is the player's main tool for studying the moon's life, and it underpins the wider genetic loop on Proteus. It was one of the first new tools revealed for Subnautica 2 and was highlighted in early promotional materials and the Dev Vlogs as a signature addition to the game's toolkit. The same sampler also feeds the BioMod pipeline, so studying creatures supports both the permanent and the reversible branches of body modification.3535The tool also ties into the crafting and resource loop. Players explore to find creatures and Angel Combs, study what they find, and unlock both Adaptations and other genetic perks, which rewards thorough exploration of each biome.3838Origins as Cut Content4040The concept behind the Adaptations system revisits an earlier idea from the studio. During earlier development, Unknown Worlds designed a tool called the Transfuser that would have let players extract and inject DNA between creatures, modifying their traits. The Transfuser was an earlier studio prototype that did not ship. For more on features that were dropped, see Cut Content.4242Subnautica 2 rebuilt the idea around the player rather than the creatures: the Biosampler is the in-fiction tool, and the Adaptations menu is the player interface. The system focuses on modifying the player, which narrows the scope of the mechanic while tying it directly to the player's personal survival journey.4444Role in the Narrative4646The Adaptations system is woven into the game's story. The Noetic Advisor guides the player through the first genetic change as part of the mission on Proteus. The framing suggests that genetic modification is not just a gameplay convenience but a planned component of the expedition, raising questions about the true nature of the mission and the directives the player is following.
