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 Log pickup and identify the landmark, depth band, or objective state before following the next step.
Use Completion check to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Blackbox route as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Log pickup
Confirm the log pickup before leaving so cleanup sweeps do not repeat the same room.
Action: Split Blackboxes into short route clusters instead of one full-map sweep.
Completion check
A completion check turns the route from a vague collectible hunt into a reliable checklist.
Action: Confirm each pickup or log state before leaving the room or wreck.
Blackbox route
Blackbox routes should be grouped into short clusters with clear exits.
Action: Mark completed clusters so later cleanup does not repeat the same dive.

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
Clear Blackboxes as a checklist route: group nearby pickups, confirm each log on screen, mark the route as complete, and stop when the next Blackbox would require a separate dive plan.
Visual checkpoint
Confirm the log pickup before leaving so cleanup sweeps do not repeat the same room.
Map anchor
Blackbox Completion Sweep in Log and wreck cleanup route. Use it for use this when cleanup starts repeating old rooms and the route needs a confirmed checklist.
Abort rule
Trying to clear every Blackbox in one oxygen or vehicle route.
Field manual translation
Clear Blackboxes as a checklist route: group nearby pickups, confirm each log on screen, mark the route as complete, and stop when the next Blackbox would require a separate dive plan. Use this completion 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.

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
- Scanner habit
- Route checklist
- Return marker
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
Completion route rhythm
Blackbox routes are easiest when each pickup has three proofs: entry landmark, pickup confirmation, and completion check. Without those, cleanup becomes a repeated search of already-cleared rooms.
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.
When to split the route
Split the checklist whenever depth, oxygen, threat pressure, or room complexity changes. A clean second dive is better than a confused completion push.

Video route notes
All Blackbox Locations should be followed as a completion route, not as a memory test. Start by watching the first route movement and naming the entry condition before copying the path in-game. Split Blackboxes into short route clusters instead of one full-map sweep. 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. Confirm each pickup or log state before leaving the room or wreck. If the route starts to feel different in your build, keep the same player goal: finish the unlock cleanly and know whether a return trip is needed.

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. Mark completed clusters so later cleanup does not repeat the same dive. 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. Trying to clear every Blackbox in one oxygen or vehicle route. Forgetting to confirm the log state after the pickup. 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 completion route into better field knowledge instead of another untracked cleanup sweep.

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.
