Video watch notes
What to pause, compare, and write down
Do not watch the video like entertainment only. Use these notes as a second-screen checklist: pause on landmarks, confirm the player action, then return to the written route.
Watchlist
Pause on Hot-route proof and identify the landmark, depth band, or objective state before following the next step.
Use Device order to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Power entry as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.

Hot-route proof
Heat Tolerance should be tested after a visible route or room-state proof.
Action: Identify the hot-zone or Angel Comb blocker before starting the route.

Device order
Follow one device or interaction order before extending the hot route.
Action: Complete the prerequisite scan, bloom, or adaptation step.

Power entry
Use the entry frame to decide whether the heat route is ready or premature.
Action: Apply Heat Tolerance and test it on a short known route.
Video route timeline
Turn the video into playable checkpoints
Use this section like a second-screen route sheet. Open each checkpoint, compare the frame, do the action, then stop if your route no longer matches the video evidence. It keeps the guide useful even when Early Access shifts small placements or creature behavior.

Route decision lab
Decide if this route is worth running now
This section turns the video into a practical in-game decision. Use it before leaving base, after the first landmark, and again before entering a deeper or darker area.
Route purpose
Unlock Heat Tolerance when a hot zone or infected Angel Comb route blocks progress. Confirm the prerequisite, apply the adaptation, then test it on a known heat route before pushing deeper.
Visual checkpoint
Heat Tolerance should be tested after a visible route or room-state proof.
Map anchor
Heat Tolerance Hot Zone Test in Hot-zone adaptation route. Use it for use this when a hot zone or infected angel comb objective is blocking the next route.
Abort rule
Entering hot routes before the adaptation is active.
Field manual translation
Unlock Heat Tolerance when a hot zone or infected Angel Comb route blocks progress. Confirm the prerequisite, apply the adaptation, then test it on a known heat route before pushing deeper. Use this completion route manual as a second-screen checklist: identify the entry condition, confirm the objective with a visual proof point, then stop when the return rule is met. This keeps the article practical for Early Access patches without pretending every coordinate or state is final.
Primary job
Heat Tolerance - Identify the hot-zone or Angel Comb blocker before starting the route.
Best entry habit
BioMod route - Complete the prerequisite scan, bloom, or adaptation step.
Stop condition
Entering hot routes before the adaptation is active. - Apply Heat Tolerance and test it on a short known route.
Patch-safe reading
Exact item positions can shift during Early Access. The useful part of this page is the route logic: what to prepare, what visual cue to confirm, what objective to finish, and when to turn back.

What this guide covers
Requirements
- BioMod route
- Heat route proof
- Abort plan
Use this if
You want a route you can follow from video evidence without needing exact official coordinates. The screenshots and steps are written to help you recognize areas, landmarks, and decisions while playing.
Early Access can move details. Treat this as a video-based walkthrough and verify landmarks in your own build.

Identify the hot-zone or Angel Comb blocker before starting the route.
Use this step as a route checkpoint, not as a promise that every object spawns in one exact coordinate. Match the landmark, compare the screenshot, then continue only if the return path is still clear.
If your game build looks different, stay with the same decision: keep oxygen safe, scan or collect the current blocker, and return before pushing into the next unknown area.

Detailed notes
Resistance is route support
Heat Tolerance helps a route become possible; it does not make every hot area safe. The guide should still show entry, proof, and exit clearly.
How to use this in-game
Turn this note into one action before leaving base: decide the objective, keep only the materials or tools that support it, then stop the route once the scan, pickup, or landmark is confirmed. This keeps the guide useful even when Early Access patches move small details.
Test before pushing deeper
After unlocking, test the adaptation in a short controlled heat route. Learn the margin before combining it with puzzle pressure or deep exploration.

Video route notes
Heat Tolerance Adaptation Guide should be followed as a completion route, not as a memory test. Start by watching the first route movement and naming the entry condition before copying the path in-game. Identify the hot-zone or Angel Comb blocker before starting the route. Then pause again when the video reaches the first visible proof point, because that is where the guide changes from general advice into an action you can repeat. Complete the prerequisite scan, bloom, or adaptation step. If the route starts to feel different in your build, keep the same player goal: finish the unlock cleanly and know whether a return trip is needed.

Screenshot checkpoints
Use screenshots as checkpoints instead of decoration. The first image should answer where the route begins, the second should show what confirms progress, and the third should explain what to do after the scan, pickup, puzzle state, or threat read is visible. Apply Heat Tolerance and test it on a short known route. This is especially important in Early Access because exact positions can drift while landmarks, depth bands, room states, and player decisions stay useful. A good screenshot lets you say, "I am at the right kind of place," before you risk oxygen, storage space, or vehicle safety.

Stop rule and next dive
The most useful part of this page is the stop rule. Entering hot routes before the adaptation is active. Treating resistance as permission to ignore oxygen or return planning. When the objective is confirmed, return and convert it into progress: craft the upgrade, sort the material, save the route note, or mark the blocker as solved. If the route fails, do not repeat the same swim blindly. Change one variable at a time: enter from a clearer landmark, reduce inventory clutter, bring the missing tool, or wait until oxygen and vehicle support match the route. That turns a failed completion route into better field knowledge instead of another untracked cleanup sweep.

Common mistakes
Entering hot routes before the adaptation is active.
Treating resistance as permission to ignore oxygen or return planning.
Skipping the room-state proof after the adaptation objective completes.
FAQ
Is this guide for the current Subnautica 2 build?
This page is written for Early Access and includes a visible update date. Treat exact values as tracking notes until the current build is field-tested.
Does this page use official screenshots?
Pages combine attributed official Steam / Unknown Worlds media, local gameplay frame captures, and source-video evidence cards. New player-submitted captures should keep the route, timestamp, and build context attached.

Near starter shallows
Approx. 70-120m from pod
Confirm oxygen before leaving the first landmark. The route is much safer when you mark the return path before collecting side materials.

Creature patrol ranges and fragment placement can shift between builds, so treat exact distances as field estimates until multiple players confirm them.
