Stuck at the Alien Power Plant in Subnautica 2 even after repairing the turbine and collecting the Angel Comb upgrade? Yeah, a lot of players are running into the exact same problem right now.
The current Early Access build has several progression bugs tied to the Alien Power Plant mission, especially around the turbine repair sequence, Axum Vision unlock, and inactive control consoles. If your Power Plant won’t activate in Subnautica 2, you’re probably dealing with a known bug rather than missing a hidden objective.
Here’s what’s actually happening — and the best fixes players have found so far.

Why the Alien Power Plant Won’t Activate in Subnautica 2
The intended progression for the Alien Power Plant mission currently looks like this:
- Find the Angel Comb near the Power Plant
- Unlock the Axum Vision adaptation upgrade
- Activate the lower control room console
- Repair the turbine above the crater
- Complete the symbol puzzle upstairs
- Activate the final Alien Power Plant console
The issue is that many players repair the turbine successfully, but the Power Plant still refuses to activate afterward.
In most cases:
- the final console stays locked,
- objectives stop updating,
- or the game fails to recognize completed steps.
This has become one of the most reported Subnautica 2 progression bugs in Early Access.
Subnautica 2 Turbine Repaired But Nothing Happens
If your turbine is repaired but nothing happens afterward, the game likely failed to trigger the next progression flag.
Players across Reddit, Steam forums, Discord servers, and community guides are reporting:
- Alien Power Plant console not working
- Axum Vision not progressing
- Angel Comb progression bug
- turbine repair not registering
- Power Plant mission softlock
- inactive control terminals
- hidden bloom nodes preventing completion
Right now, the bug appears tied to infection bloom cleanup and mission trigger order.

Best Fixes for the Subnautica 2 Power Plant Bug
Until the developers release a full patch, these are the most reliable workarounds players have found.
Double-Check Every Bloom and Canker Node
This is the fix that works most often.
Some players discovered one hidden bloom or canker near the crater, wreckage, or ravine remained active even after clearing the main area.
If even one infected node remains:
- the turbine sequence may not complete,
- and the Alien Power Plant won’t activate.
Carefully revisit:
- the turbine area,
- lower crater tunnels,
- side caves,
- and debris piles.
This is currently the biggest cause of the Subnautica 2 Power Plant progression bug.
Return to the Lower Control Console
After repairing the turbine, swim back to the lower control room and interact with the original console again.
Several players report the mission progression resumes only after revisiting the first terminal manually.
The game sometimes skips the next trigger entirely after loading zones or saving.
Save, Quit, and Reload the Area
Classic survival-game fix, but it genuinely works here.
Try this sequence:
- Save the game manually
- Fully quit to desktop
- Reload your save
- Leave the biome completely
- Return to the Alien Power Plant
Some players say the console finally became interactable after reloading the area.
Re-Interact With the Turbine
Even if the turbine already looks repaired, the interaction may not have registered correctly.
Go back and:
- scan nearby components,
- interact with repair prompts again,
- and check for unfinished animations or missing sound triggers.
The turbine repair bug is one of the most common Early Access issues right now.
Co-Op Players Should Let the Host Trigger Everything
Multiplayer progression is especially unstable in the current build.
If you’re playing co-op:
- let the host repair the turbine,
- activate all consoles,
- and trigger story objectives personally.
Clients frequently fail to sync mission progression properly.
Can the Alien Power Plant Bug Softlock Your Save?
Unfortunately, yes.
Some players report the mission becoming permanently stuck even after trying every workaround. In those cases, the only current solutions are:
- loading an older save,
- replaying the area,
- or waiting for an upcoming hotfix.
Because Subnautica 2 is still in Early Access, progression bugs like this are fairly common right now.
Final Verdict
If the Alien Power Plant won’t activate after repairing the turbine in Subnautica 2, you’re most likely dealing with a known progression bug tied to the Angel Comb mission and infection cleanup triggers.
The best current fixes are:
- clearing every hidden bloom,
- revisiting the lower control room,
- reloading the biome,
- and re-triggering turbine interactions.
Until Unknown Worlds patches the issue, these community-discovered workarounds are the closest thing to a reliable fix.
