Watch or inspect the route before you dive
Click YouTube cards to load the player. Open frame cards to compare local screenshot notes. Use the evidence to confirm landmarks, movement, and encounter pacing, then follow the written checklist below.
Biome maps and secret locations
Watch for: Biome landmarks, route bands, secret-site recognition, and how to read the map before diving.
Map and biome route comparison
Watch for: Alternative map footage, landmark confirmation, and route planning context.
Biome landmark frame review
Watch for: Start with Biome maps and secret locations at 03:03. Compare the screenshot cue, route note, and player action before following the guide in-game.

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 Biome landmark and identify the landmark, depth band, or objective state before following the next step.
Use Route band to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Secret site as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Biome landmark
Map pages should teach landmark recognition before listing every possible marker.
Action: Identify the biome landmark before checking secret markers.
Route band
A route band is more useful than a brittle coordinate when Early Access placements move.
Action: Write down the route band instead of trusting a single coordinate.
Secret site
Secret locations should be saved as spoiler-controlled checkpoints with a clear return path.
Action: Check hazard level and oxygen pressure before entering side paths.

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
Use biome guides as landmark maps, not just coordinate dumps. Learn the terrain shape, route band, hazard level, and return path before chasing secret locations.
Visual checkpoint
Map pages should teach landmark recognition before listing every possible marker.
Map anchor
Biomes and Secret Locations Grid in Secret location route grid. Use it for use this when you know a secret exists but need recognition clues for terrain and depth.
Abort rule
Using map screenshots without learning the landmark shape.
Field manual translation
Use biome guides as landmark maps, not just coordinate dumps. Learn the terrain shape, route band, hazard level, and return path before chasing secret locations. Use this resource 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
Map-first - Identify the biome landmark before checking secret markers.
Best entry habit
Route notes - Write down the route band instead of trusting a single coordinate.
Stop condition
Using map screenshots without learning the landmark shape. - Check hazard level and oxygen pressure before entering side paths.
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
- Route notes
- Scanner
- Return oxygen margin
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.

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
Map pages should teach recognition
The best map guide helps players recognize terrain. Landmark shape, color, depth feel, hazards, and nearby resources make a route repeatable even when exact markers change.
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.
Secret location format
A secret site should record entrance clue, route risk, required tool, reward type, and spoiler level. That lets players choose how much help they want.

Use route bands during Early Access
Route bands are safer than brittle coordinates while the map changes. A route band says roughly where to travel, what terrain to expect, and when to turn back.

Practical field read
Biomes Map and Secret Locations works best when you treat it as a material or fragment route with a narrow job. Start with the loadout check: Route notes. Then follow the first action without adding side goals: Identify the biome landmark before checking secret markers.. The page should help you recognize the visual proof that the route is producing the right item before you risk a longer dive. If the route starts producing unrelated discoveries, bank the note and return to the original objective instead of turning one guide into a full map sweep.

How to turn this into the next dive
After the first proof point, decide whether the route is solved, blocked, or worth repeating. Write down the route band instead of trusting a single coordinate.. If it is solved, return and convert the result into crafting, storage, a map note, or the next related guide. If it is blocked, change only one variable: bring the missing tool, clear inventory, enter from a cleaner landmark, or wait for better oxygen and vehicle support. Check hazard level and oxygen pressure before entering side paths.. Avoid the two habits that make this route feel unreliable: Using map screenshots without learning the landmark shape.; Opening spoiler locations before the route is safe..

Video route notes
Biomes Map and Secret Locations should be followed as a resource 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 biome landmark before checking secret markers. 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. Write down the route band instead of trusting a single coordinate. If the route starts to feel different in your build, keep the same player goal: repeat the route without relying on a perfect coordinate.

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. Check hazard level and oxygen pressure before entering side paths. 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. Using map screenshots without learning the landmark shape. Opening spoiler locations before the route is safe. 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 resource route into better field knowledge instead of another full-inventory wander.

Common mistakes
Using map screenshots without learning the landmark shape.
Opening spoiler locations before the route is safe.
Treating every old coordinate as current after updates.
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.
Guide-wide
N/A
Creature patrol ranges and fragment placement can shift between builds, so treat exact distances as field estimates until multiple players confirm them.
