Cyclops Fire Suppression System

Automatically extinguishes fires caused by incoming damage; when activated, its suppression cycle extinguishes fires and evacuates smoke.

How it works

The module description says it automatically extinguishes fires resulting from incoming damage, preserving the majority of the Cyclops' hull integrity. The damage-control display can activate it if installed. Activation closes and locks all bulkheads and flashes a blue light; after a few seconds, fires are extinguished and smoke evacuates. The system needs time to recharge before reuse, about two minutes.

Read the supporting references

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. Guidance explains the referenced mechanics; it is not a tested damage ranking. Check the stated edition and source version before applying a patch-specific detail.
