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 Shelter anchor and identify the landmark, depth band, or objective state before following the next step.
Use Useful pickup to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Return proof as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Shelter anchor
Start the first hour by naming the shelter and a route you can repeat.
Action: Mark the shelter and the safest shallow return lane.
Useful pickup
Pick up or scan only what solves the next craft or objective.
Action: Solve one oxygen or tool blocker before chasing distant signals.
Return proof
A first-hour route is successful when the return line is still obvious.
Action: Scan or gather only the item tied to the next craft.

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
Treat the first hour as five short loops: confirm shelter, solve the first oxygen blocker, scan one useful unlock, gather one recipe set, and return before route memory fades.

Field manual translation
Treat the first hour as five short loops: confirm shelter, solve the first oxygen blocker, scan one useful unlock, gather one recipe set, and return before route memory fades. Use this progression 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
First hour - Mark the shelter and the safest shallow return lane.
Best entry habit
Shelter landmark - Solve one oxygen or tool blocker before chasing distant signals.
Stop condition
Turning the opening hour into a full-map tour. - Scan or gather only the item tied to the next craft.
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
- Shelter landmark
- Scanner target
- Recipe blocker
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
Mark the shelter and the safest shallow return lane.
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
first-hour checklist route plan
First Hour Route Checklist is useful when the route is treated as a focused job instead of a full-map sweep. Start by naming the blocker, checking the loadout, and matching the first landmark before copying the video. The player goal is not to memorize every second of movement; it is to understand why the route begins there, what proves progress, and when the route should stop.
Route type: first-hour checklist
Proof to confirm: crafted tool, scan progress, or safe return proof
Primary blocker: Shelter landmark
Best follow-up: Return, craft, store, and start the next short loop.
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.
How to use the video evidence
Watch for the entry frame, the proof frame, and the exit frame. The entry frame tells you whether you are in the right terrain band. The proof frame tells you whether the scan, pickup, blueprint, puzzle state, or build decision actually happened. The exit frame protects the run from turning into a panic search after the objective is already solved.
Entry frame: match terrain before diving deeper
Proof frame: confirm crafted tool, scan progress, or safe return proof
Exit frame: return before adding side goals

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.
Stop rule
Stop each loop when one practical upgrade, craft, or route note is complete. If the route fails, change one variable before trying again: bring the missing tool, empty inventory, approach from a clearer landmark, or wait until oxygen, vehicle depth, or defensive options match the route. That makes the next attempt safer and gives the page useful field notes instead of repeated guesswork.

Video route notes
First Hour Route Checklist should be followed as a progression route, not as a memory test. Start by watching the first route movement and naming the entry condition before copying the path in-game. Mark the shelter and the safest shallow return lane. 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. Solve one oxygen or tool blocker before chasing distant signals. If the route starts to feel different in your build, keep the same player goal: turn the video into a safe repeatable session plan.
Entry check: Shelter landmark
Route action: Mark the shelter and the safest shallow return lane.
Proof to look for: objective 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. Scan or gather only the item tied to the next craft. 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 objective proof
Exit frame: know the return direction before adding side goals
Loadout frame: check Scanner target

Stop rule and next dive
The most useful part of this page is the stop rule. Turning the opening hour into a full-map tour. Leaving without a named route objective. 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 progression route into better field knowledge instead of another overextended dive.

Common mistakes
Turning the opening hour into a full-map tour.
Leaving without a named route objective.
Continuing after inventory, oxygen, or route memory is already strained.
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.
