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 Class recognition and identify the landmark, depth band, or objective state before following the next step.
Use Aggro posture to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Route breakaway as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Class recognition
Use size, silhouette, and movement line to separate Leviathan-class threats from ambient fauna.
Action: Observe the zone edge before diving in.
Aggro posture
When the body angle turns toward the player, stop advancing and prepare the exit.
Action: Mark a return path and a fallback shelter.
Route breakaway
A repeatable Leviathan route records cover, open water, and the breakaway direction.
Action: Complete one objective per entry.

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
Do not treat leviathan-class zones as normal resource routes. Enter with an exit plan, scan from controlled angles, and leave as soon as the objective is complete.
Visual checkpoint
Use size, silhouette, and movement line to separate Leviathan-class threats from ambient fauna.
Map anchor
Leviathan Class Scout Line in Outer leviathan patrol edge. Use it for use this as the safe edge of the encounter, not as the target itself.
Abort rule
Trying to gather everything in one pass.
Field manual translation
Do not treat leviathan-class zones as normal resource routes. Enter with an exit plan, scan from controlled angles, and leave as soon as the objective is complete. 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
Severe - Observe the zone edge before diving in.
Best entry habit
Reliable mobility - Mark a return path and a fallback shelter.
Stop condition
Trying to gather everything in one pass. - Complete one objective per entry.
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
- Reliable mobility
- Oxygen margin
- Empty inventory space
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.

Observe the zone edge before diving in.
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
Use edge scouting first
The edge of a threat zone teaches movement, visibility, and exit options with less risk than pushing straight to the center.
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.
What to record for later verification
Future field-tested versions should record patrol range, trigger distance, escape terrain, and the safest scan window.

Leviathan routes need an abort plan first
Do not begin a leviathan-class route by thinking about the scan or screenshot. Begin with the exit. Identify cover, distance, oxygen margin, vehicle position, and the point where you leave even if the objective is not complete. The safer route is usually the one that looks slower on video but gives you more time to make a clean decision.

What counts as progress near a leviathan
Progress can be a confirmed patrol area, a safe rock shelter, a repeated approach line, or a better read on the attack window. You do not need the scan on the first attempt. Bank the route knowledge, improve the loadout, and return with one changed variable instead of repeating the same risky swim.

Video route notes
Leviathan-Class Threats 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. Observe the zone edge before diving in. 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. Mark a return path and a fallback shelter. If the route starts to feel different in your build, keep the same player goal: recognize the danger window before committing to the approach.
Entry check: Reliable mobility

Proof to look for: creature behavior proof

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. Complete one objective per entry. 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
Proof frame: confirm creature behavior proof
Exit frame: know the return direction before adding side goals
Loadout frame: check Oxygen margin

Stop rule and next dive
The most useful part of this page is the stop rule. Trying to gather everything in one pass. Entering with valuable materials in inventory. 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.

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.

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