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 Activation room and identify the landmark, depth band, or objective state before following the next step.
Use Deep entry to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Power device as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Activation room
Turbine routes should end with a placement or power-output decision.
Action: Check whether your base location can use turbine-style power.
Deep entry
Deep-entry proof keeps power-fragment routes from becoming blind exploration.
Action: Follow the fragment route and confirm scan progress after each stop.
Power device
Power devices need route context, blueprint proof, and a base job.
Action: Return when the blueprint completes instead of clearing extra rooms.
Video route timeline
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
Use the Hydroelectric Turbine when the base has a suitable flow route. Scan the fragments, confirm blueprint progress, then place it where power output supports the base instead of forcing awkward travel.
Visual checkpoint
Turbine routes should end with a placement or power-output decision.
Map anchor
Hydroelectric Turbine Fragment Route in Water-flow power route. Use it for use this before rebuilding power so the turbine route is tied to a placement test.
Abort rule
Unlocking the turbine without a placement plan.
Field manual translation
Use the Hydroelectric Turbine when the base has a suitable flow route. Scan the fragments, confirm blueprint progress, then place it where power output supports the base instead of forcing awkward travel. 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.
Primary job
Hydroelectric Turbine - Check whether your base location can use turbine-style power.
Best entry habit
Scanner - Follow the fragment route and confirm scan progress after each stop.
Stop condition
Unlocking the turbine without a placement plan. - Return when the blueprint completes instead of clearing extra rooms.
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
- Power route
- Placement check
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
Check whether your base location can use turbine-style power.
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
Power depends on placement
The turbine is only as useful as the route and site around it. Treat the guide as both a fragment path and a placement decision.
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.
Scan-to-build loop
The route should end with a real base test: scan, craft, place, read output, and decide whether it belongs in the main power plan.

Video route notes
Hydroelectric Turbine Guide 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. Check whether your base location can use turbine-style power. 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. Follow the fragment route and confirm scan progress after each stop. 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. Return when the blueprint completes instead of clearing extra rooms. 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. Unlocking the turbine without a placement plan. Scanning fragments while ignoring the return route. 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.
