Cyclops Thermal Reactor
The Cyclops Thermal Reactor is a heat-powered main reactor that converts ambient lava zone temperature into electricity, granting the Cyclops nearly unlimited range when exploring the deepest volcanic biomes.
Quick Info
Description
The Cyclops Thermal Reactor replaces the default power cell infrastructure with a thermal generator that harvests energy from the searing temperatures of lava zones. Inside the Lava Castle or Inactive Lava Zone, the reactor produces enough electricity to keep engines, floodlights, sonar, and shields running indefinitely. Outside those biomes, output drops sharply and standard power cells are still required.
How to Get
Recover the blueprint by scanning data boxes inside Cyclops wreckage in the Inactive Lava Zone or by scanning fragments near deep thermal vents. Bring a Prawn Suit with a Grappling Arm for vertical lava castle exploration.
Materials Required
- 4x TitaniumMined from limestone
- 2x LithiumMined from shale
- 1x Computer Chip2x Copper + 2x Gold
Crafting Station
Modification Station — install in the Cyclops upgrade console.
High-tier power upgradeUses & Tips
Plan a long expedition to the Lava Castle with this reactor installed. Pair it with the Cyclops Shield Module and Sonar Module for full coverage in the most hostile biomes.
Infinite Power
Generates a continuous stream of power inside lava zones, eliminating the need for spare power cells.
Heat Conversion
Output scales with ambient temperature; warmer biomes mean more charge per minute.
Cold-Water Penalty
Output drops to nearly zero outside lava zones; swap back to power cells for surface expeditions.

What does the Cyclops Thermal Reactor do?
It replaces the default power cell infrastructure with a thermal reactor that converts ambient heat into electricity, granting nearly unlimited range in lava zones. Heat is absorbed through the hull plating and converted to power.
Does the Thermal Reactor work outside lava zones?
Outside lava zones the reactor produces very little energy and should be swapped back to standard power cells. Plan to install the reactor at a dock right before descending through the Lost River.
Where do I find the Thermal Reactor blueprint?
The blueprint is acquired by scanning data boxes inside Cyclops wreckage in the Inactive Lava Zone or by scanning fragments in deep thermal vents. Bring a Prawn Suit with the Drill Arm to break into locked wreckage.
