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

1

Pause on Threat roster and identify the landmark, depth band, or objective state before following the next step.

2

Use Attack cue to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.

3

Treat Escape line as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.

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

Prepare for major threats by scouting exits, carrying only mission-critical items, scanning from safety, and leaving before the encounter turns into a panic route.

Field manual translation

Prepare for major threats by scouting exits, carrying only mission-critical items, scanning from safety, and leaving before the encounter turns into a panic 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

High - Scout the area before committing to scans or loot.

Best entry habit

Oxygen buffer - Identify exits and safe terrain.

Stop condition

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

  • Oxygen buffer
  • Escape route
  • Low-value inventory

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.

Step-by-step walkthrough

Follow the video route without guessing

1

Scout the area before committing to scans or loot.

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

Bosses in a survival game are route tests

Subnautica threats usually test preparation more than damage output. This first version tracks preparation patterns until exact encounter mechanics are verified.

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.

Threat file checklist

Each future encounter page should record trigger, safe approach, scan window, escape route, reward, and patch notes.

Threat pages are preparation pages

A major threat guide should not encourage players to race toward danger. Its job is to teach recognition, approach angle, abort timing, and what the encounter blocks. Before entering a threat route, decide whether the objective is observation, scanning, escape practice, or progression. Mixing those goals usually turns a controlled approach into a panic retreat.

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.

How to use video evidence safely

When a video shows a creature route, watch the terrain more than the dramatic moment. Note where the player had cover, when visibility changed, and what escape lane remained open. If your build or route does not match those conditions, treat the video as behavior evidence rather than a command to copy the exact swim.

Video route notes

Bosses and Threats Overview 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. Scout the area before committing to scans or loot. 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. Identify exits and safe terrain. 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. Avoid carrying rare resources into unknown threats. 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. Treating a first encounter like a fight to win. Trying to scan while cornered. 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.
