Quick answer
For power routing, trace visible inputs and outputs first, then inspect inactive devices from source to destination. If nothing reacts, you likely need a scan, item, or later unlock.
Second-screen dive plan
What to do, what proves it, and when to leave
Locate the power source or inactive terminal.
Power device at 02:28
Trace visible connections, scan every interactable, trigger one state change, then confirm what opened.
Puzzle Guide Overview
Power device
Power puzzles start with the device that clearly changes room state.
Approach
Trace visible connections, scan every interactable, trigger one state change, then confirm what opened.
Objective
Power puzzle anchor for tracing room-state changes before interacting with terminals.
Return
Use this when switches, turbines, power lines, or locked states need a readable order.
Tactical brief
How to use this guide in a real dive
Power Routing Puzzles is useful when the player needs a repeatable decision path, not just a short answer. Start with the page objective, then compare the map anchor, the first evidence frame, and the current Early Access status before committing to a longer dive. This keeps the guide practical when Subnautica 2 routes shift between patches.
On the atlas, this guide is tied to Power Routing Node. Treat that marker as a route anchor: Power puzzle anchor for tracing room-state changes before interacting with terminals. The important player action is not simply reaching the dot, but using it to decide when to approach, what to scan or gather, and how to leave cleanly.
The first visual check is Power device (02:28). Use that frame as the reading order for the rest of the article: identify the landmark, confirm the objective, then watch for the mistake that would force a reset. Power puzzles start with the device that clearly changes room state.

Field manual
Power Routing Puzzles field manual
Built from the supplied route videos and local frame captures so the article teaches what to watch for, not only what to click.
For power routing, trace visible inputs and outputs first, then inspect inactive devices from source to destination. If nothing reacts, you likely need a scan, item, or later unlock. Use this state-change 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
Power
Locate the power source or inactive terminal.
Best entry habit
Scanner
Trace visible lines, symbols, or repeated devices.
Stop condition
Interacting randomly before tracing the circuit.
Scan each interactable before spending resources.
What to watch in the videos
Pause on Power device 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 Activation room as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Decision table
Interacting randomly before tracing the circuit.
Reset to the last confirmed landmark or objective state, then repeat only the route-critical step.
Ignoring devices that look decorative.
Use the video frame as evidence, but record entry, proof, and exit as separate notes.
Trying to solve while the oxygen timer is already tight.
Return, craft, sort storage, or retest the route before turning this page into a longer objective chain.

Route anchors for this guide
Power Routing Node
Power puzzle anchor for tracing room-state changes before interacting with terminals.
Player use
Use this when switches, turbines, power lines, or locked states need a readable order.
Route hint
Trace visible connections, scan every interactable, trigger one state change, then confirm what opened.
Puzzle route logic
Entry, trigger, proof, and reset
Use this matrix when a door, turbine, keycode, wreck room, or alien facility step does not clearly advance.
The goal is to identify the last confirmed state change, then avoid wasting oxygen on random interactions.
Alien Observatory turbine activation
Entry check
Enter the observatory route with the current objective visible and avoid touching devices before reading the room.
Trigger
Interact with the turbine or symbol sequence only after the room state and door target are understood.
Proof of progress
A solved step changes the door, turbine, or objective state; if nothing changes, the sequence is not confirmed.
Reset rule
Return to the previous room state and repeat the last confirmed interaction instead of trying random devices.
Giant Alien Power Plant startup
Entry check
Treat the route into the plant as part of the puzzle and confirm a return path before activation attempts.
Trigger
Start with the power device that visibly changes room state before moving to deeper activation rooms.
Proof of progress
The room should show an activation result or objective update before the player leaves the sequence.
Reset rule
If activation feedback is unclear, stop extending the route and re-check the previous power device.
Alien structure room reading
Entry check
Before pressing anything, read symbols, powered devices, locked doors, and objective text as separate clues.
Trigger
Interact only with the device that matches the current clue order or visible room state.
Proof of progress
The next door, turbine, bridge, or objective state should change in a way the player can describe.
Reset rule
If the room becomes ambiguous, return to the last visible state change and rebuild the sequence from there.

Guide notes
Trace, then touch
A power puzzle is easiest when you read the room before interacting. Route first, inputs second, actions third.
When a power puzzle is not ready
Inactive rooms often signal missing tools or story state. If scanning gives no clue and no device responds, mark it and return later.
