Subnautica 2 Adaptive Measures guide
What Adaptive Measures changed
Early Access 1.1 is officially named Adaptive Measures. Unknown Worlds released it as a free automatic update focused on progression, exploration, movement, base placement, and settings. It was later followed by Buddy System in Early Access 1.2, so treat the changes below as a version checkpoint rather than a promise that every balance value is unchanged today.
| System | Verified 1.1 change | Practical result |
|---|---|---|
| Biomods | Biolab unlocks increased from four to six Biomods | More early progression choices |
| Bioscanner | Scanning creatures can unlock passive Biomod slots | Scan routinely while traveling |
| Movement | Players can sprint when out of the water, on the surface, or in a base | Faster base and surface travel |
| Settings | An FOV slider was added | Set field of view before long sessions |
| Audio logs | Audiologs no longer auto-play; they enter the PDA for manual replay | Listen when it is safe to pause |
| Base building | Placement feedback and several footprints improved | Plan large bases with fewer ambiguous ghosts |
Confirm your version
The official update article describes Adaptive Measures as a free automatic download. If the update does not appear, Unknown Worlds recommends restarting the game client rather than looking for a separate product. That advice is version-specific: after 1.2 and its hotfixes, first confirm the installed build before blaming the client or the account. This page records the 1.1 feature set from the official announcement. Later patches can adjust movement speed, scanning requirements, creature reactions, building rules, or interface behavior. For the newest shipped changes, start with the update tracker, then compare the feature's introduction date with the current version.
Plan Biomods and scanning
Adaptive Measures smoothed early Biomod progression and added two more Biolabs: one in Coral Gardens and one in Axum Ruins. Together, the Biolabs can unlock six Biomods, an increase from four. The update also makes Creative mode a convenient preview environment because every Biomod is unlocked there by default. Scanning remains the other half of the progression loop. Using the Bioscanner on creatures can unlock additional passive Biomod slots. The interface shows the scans required for each slot and the player's total Bioscans, so you do not need to guess whether a scan contributed to progression.
| Goal | Useful route | Boundary |
|---|---|---|
| Compare Biomods | Visit the two new Biolabs in Coral Gardens and Axum Ruins | Exact route coordinates were not captured |
| Open passive options | Scan creatures with the Bioscanner | Do not assume every creature unlocks a slot |
| Test a full loadout | Use Creative mode, where all Biomods are unlocked by default | Creative does not prove Survival balance |
| Avoid wasted scans | Read the displayed scan requirement and total first | Current numbers may differ after later patches |
Move, explore, and manage threats
The movement change is straightforward: players can sprint when out of the water, while swimming at the surface, or inside a base. A default mapping supports remapping, but this guide does not publish a key because the official captured source does not specify one. Default walking speed was reduced to balance sprinting, so expect the pace profile to differ rather than treating the new sprint as a pure speed increase. Wreck exploration added traversal and oxygen puzzles, made doors and buttons use a more consistent visual language, and adjusted some rewards. That is useful for players who found earlier wreck navigation ambiguous, but it is not a coordinate guide. Most creatures now flee after being attacked with the Survival Multitool, while hits from the Sonic Resonator can briefly make many creatures dizzy. Use those reactions as escape tools, not as permission to fight everything. Silver also received updates in Coral Gardens and a nearby hint line. Creature behavior and hint placement should be rechecked after major patches because official update notes describe intended changes, not an immutable behavior table.
Tune settings and audio
Adaptive Measures added an FOV slider. If narrow framing causes discomfort, set it before a long dive and test it in both confined wrecks and open water. The update also fixed a problem that could cap some gaming laptops with an Nvidia GPU at 60 FPS. The fix is historically relevant, but it does not replace checking the current driver, power profile, and game build when troubleshooting performance. Audio behavior also changed direction. Audiologs no longer auto-play. They notify the player, enter the PDA, and can be replayed by that individual player. This is helpful when a log is discovered during oxygen management or creature avoidance: acknowledge it, continue to safety, then listen from the PDA. The official source does not describe every replay control, so confirm the interface in your current build.
Build with clearer placement
Base builders received several quality-of-life changes. Adaptive Measures increased the maximum size of a base that can be deconstructed, improved placement ghosts, and made Vehicle Dock and Fabricator placement feedback clearer. Vehicle Dock platforms and tracks use less space than before, which matters when planning a dock near a tight shoreline or existing corridor. The update also added a storage buildable that does not contribute to nearby crafting systems. That gives builders a way to organize inventory without changing how nearby crafting reads materials. This page does not publish component costs, dimensions, or a universal layout because those values were not captured and may have changed since 1.1. For hardware context before a larger build session, see the system requirements guide.
Turn the update into a routine
A practical Adaptive Measures routine is: confirm the build, visit the two new Biolabs, scan creatures toward passive slots, set the FOV slider, then test sprint and storage layout in a controlled area. Players organizing a squad should also understand the later Buddy System additions and the broader co-op rules in the multiplayer guide. For proximity chat, revives, emotes, and trading, see the Buddy System guide. The Xbox multiplayer notice is account-related rather than a gameplay mechanic. Non-subscribers entering multiplayer or joining an online session may see a notice that a Game Pass subscription of any tier is required to play multiplayer. Verify the current account state in the Xbox interface before interpreting the message as a network error.
Evidence boundaries
This guide is based on Unknown Worlds' official Adaptive Measures article and the Steam news record confirming the 1.1 headline. Exact controls, coordinates, complete setting paths, precise balance values, platform differences, and current behavior after later patches were not captured. Do not treat community recipes or map claims as official instructions without a live-build check.
Common search questions
What is Subnautica 2 Adaptive Measures?
Adaptive Measures is the official name for Early Access 1.1. It added progression, movement, settings, base-building, and audio-log improvements as a free automatic update.
How many Biomods can Biolabs unlock?
Adaptive Measures raised the Biomods unlockable from Biolabs from four to six and added Biolabs in Coral Gardens and Axum Ruins.
How do you unlock passive Biomod slots?
Scan creatures with the Bioscanner. The interface shows the scans required for each slot unlock and the player's total Bioscans.
Can you sprint in Subnautica 2?
Yes, since Adaptive Measures. Players can sprint when out of the water, at the surface, or inside a base. The default mapping can be remapped, and default walking speed was reduced for balance.
Do audiologs still play automatically?
No. Audiologs no longer auto-play; they send a notification, enter the PDA, and can be replayed manually by the player.
