What to know
- The Feedback Resonator upgrades your basic Sonic Resonator to handle shielded Cankers.
- Two blueprint fragments must be scanned near the Alien Ruins to unlock the schematic.
- Crafting requires gathering Creature Enamel, Conduit Crystals, and Celestine to make Strontium.
- The final tool is assembled at the Modification Station using the gathered components.
Navigating the deeper, more hazardous biomes in Subnautica 2 eventually requires upgrading your equipment to deal with tougher obstacles. The Feedback Resonator becomes absolutely essential once shielded Cankers begin to block your path, as the standard Sonic Resonator will no longer be enough.
Unlocking this tool requires tracking down two specific blueprint fragments and gathering some specialized materials to construct the final upgrade.

The journey to unlock and craft the Feedback Resonator revolves heavily around the Alien Ruins, which serve as your primary navigational anchor. From these ruins, you will need to descend into a deep, irradiated zone marked by a distinct green glow to find the blueprint fragments. The surrounding eastern regions and specific rock faces near the ruins also harbor the raw materials required for the upgrade, making the entire area crucial for this stage of progression.
How to find the Feedback Resonator blueprint fragments
Step 1
Start your journey at the Alien Ruins, using it as a reliable base landmark for your navigation.
Step 2
Travel from the ruins into the deep descent, heading towards the area illuminated by a distinct green glow that resembles radiation.
Step 3
Navigate your vehicle carefully down the cliff face and locate the first Feedback Resonator schematic resting among the unusual structures in the glowing zone, then scan it.
Step 4
Turn from the first fragment and head a short distance further along the rock face to discover the second schematic location.
Step 5
Scan the second fragment to fully unlock the Feedback Resonator blueprint for your Modification Station.
How to gather materials for the Feedback Resonator
Step 1
Search the far eastern region near the Alien Power Plant and Alien Ruins to mine Conduit Crystals.
Step 2
Collect Celestine from the resource nodes in the same eastern area, which you will need for intermediate crafting.
Step 3
Return to a Configure Processor and use the gathered Celestine to synthesize Strontium.
Step 4
Locate Creature Enamel deposits along the rock faces southeast of the Alien Ruins and harvest them.
Step 5
Use the Fabricator to combine the Creature Enamel with regular Glass to craft Enameled Glass.
Feedback Resonator crafting requirements
| Material | Quantity | Source |
|---|---|---|
| Sonic Resonator | 1 | Base tool to be upgraded |
| Conduit Crystal | 2 | Eastern region deposits |
| Enameled Glass | 2 | Crafted from Creature Enamel and Glass |
| Strontium | 2 | Crafted from Celestine |
Equip your new Feedback Resonator
Once all the fragments are scanned and the materials are refined, head directly to your Modification Station to bring everything together.
Combining the standard Sonic Resonator with the Conduit Crystals, Enameled Glass, and Strontium will yield the Feedback Resonator. With this powerful upgrade in your inventory, you can confidently return to the depths and easily shatter the shielded Cankers that previously blocked your exploration paths.
