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 Abort line and identify the landmark, depth band, or objective state before following the next step.
Use Size read to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Threat entry as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Abort line
Every Leviathan scan route needs a visible abort line before the scan starts.
Action: Pick the Leviathan scan target and review its route page first.
Size read
Use size, posture, and turn direction to decide whether the scan window is real.
Action: Approach from cover or terrain that breaks the direct line.
Threat entry
Threat entries should begin as observation routes, not direct charges.
Action: Wait for a readable pass before starting the scan.

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
Scan Leviathans only when the route has cover, a readable behavior window, and a visible exit. Approach to observe first, scan during the safe pass, then leave before the creature resets the route.
Visual checkpoint
Every Leviathan scan route needs a visible abort line before the scan starts.
Map anchor
Leviathan Safe Scan Route in Leviathan scan corridor. Use it for use this before attempting collector, shiver, great jaw, or deepwing-style scan routes.
Abort rule
Swimming straight at a Leviathan because the marker is visible.
Field manual translation
Scan Leviathans only when the route has cover, a readable behavior window, and a visible exit. Approach to observe first, scan during the safe pass, then leave before the creature resets the route. Use this threat 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
Safe scans - Pick the Leviathan scan target and review its route page first.
Best entry habit
Bio Scanner - Approach from cover or terrain that breaks the direct line.
Stop condition
Swimming straight at a Leviathan because the marker is visible. - Wait for a readable pass before starting the scan.
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
- Bio Scanner
- Cover route
- Exit line
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
Observe before scanning
The safest scan routes start with behavior reading. If you do not know the turn pattern, approach lane, and cover point, the scan attempt is premature.
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.
Abort rule
Abort before panic. A failed scan with a clean route note is better than a completed scan that costs the inventory, vehicle, or route confidence.

Video route notes
Leviathan Scan Routes Guide should be followed as a threat route, not as a memory test. Start by watching the first route movement and naming the entry condition before copying the path in-game. Pick the Leviathan scan target and review its route page first. 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. Approach from cover or terrain that breaks the direct line. If the route starts to feel different in your build, keep the same player goal: recognize the danger window before committing to the approach.

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. Wait for a readable pass before starting the scan. 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.
Entry frame: match the landmark before moving deeper

Stop rule and next dive
The most useful part of this page is the stop rule. Swimming straight at a Leviathan because the marker is visible. Scanning after the escape line has already disappeared. 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 threat route into better field knowledge instead of another late retreat.

Swimming straight at a Leviathan because the marker is visible.
Scanning after the escape line has already disappeared.
Repeating a failed approach without changing cover or timing.
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.
