This reference covers the Cyclops, a player-controlled submarine that can carry a Seamoth or Prawn Suit, and ten of its named upgrade modules. The modules affect crush depth, engine efficiency, power replenishment, terrain readings, fire response, docked-vehicle repair, decoy capacity, and shielding. The source says modules are made at the Cyclops Upgrade Fabricator and installed or removed through a six-slot panel in the engine room. Some effects depend on ambient heat, activation, or whether a vehicle is docked. These records describe the retrieved Subnautica passage; they are not an optimization guide, and details beyond that passage remain unverified.

If you are checking recorded crush-depth progression, compare the MK1, MK2, and MK3 values and note that the source says the depth effect does not stack.
If you are looking for navigation, fire response, vehicle repair, or decoy capacity, read the corresponding module records for their stated functions and conditions.
The source explicitly says the Depth Module effect does not stack. Read the listed MK1, MK2, and MK3 crush-depth values as module levels rather than additive effects from multiple modules.
The Thermal Reactor Module replenishes power in areas above 30°C, and the listed charge rate varies with temperature, reaching its stated maximum at 60°C.
The page lists Silent Running, Shield Generator, Sonar, and powered placeable items as energy consumers. It does not provide a specific consumption amount for every module described here.
A factual reference to the original Subnautica's Cyclops submarine and ten named upgrade modules. It records effects, limits, operating conditions, and upgrade-system details stated in the retrieved Cyclops passage. Comparative effectiveness is not assessed.
Only the Cyclops wiki passage supports the mechanics records; the retrieved Below Zero discussion and Subnautica 2 guide concern different games and were excluded.
This reference does not verify whether the passage reflects the latest game version, and does not cover every Cyclops module or other tools, vehicles, blueprints, and equipment upgrades.
The passage does not establish specific crafting costs or detailed acquisition conditions for most modules.
Explanations prepared with GPT-6 Luna and checked against the linked references. These are source-reviewed guides. They do not establish independently tested optimal builds or exact upgrade budgets. How coverage works.
