Cryofluid

Cryofluid is a specialised coolant liquid used across production, defense, and power systems. It serves as the liquid coolant for reactors and certain factories, functions as ammo for liquid-fed turrets, extinguishes burning status on contact, and applies the Freezing status to enemies it touches. Cryofluid appears on Serpo and is produced from Water as an upstream ingredient.

Cryofluid’s role is primarily thermal management and battlefield utility. It is used to cool Impact Reactor and Thorium Reactor installations and to cool turrets and other machinery that accept liquid coolants. In turret use it acts both as a coolant and as liquid ammunition for those gun types that accept liquids, providing defensive value by quenching fires and slowing or freezing hostile units that come into contact with it. Cryofluid also interacts with Mending functionality, enabling significantly faster repair speeds when used by that building. Visually, Cryofluid glows in the dark.

• Key physical and game properties: explosive 0%, burning 0%, heat capacity 40%, viscosity 50%, temperature 50%, boiling point 0.5. Its internal liquid ID is cryofluid and its display color is #6ECDEC. Water is the upstream product used to obtain Cryofluid.
• Combat and utility interactions: Cryofluid extinguishes fire effects and applies Freezing to enemies on contact, making it useful on front-line turrets and defensive chokepoints. Some higher-tech turret variants do not accept Cryofluid and instead require Water; check a turret’s accepted liquids before committing pipelines.
• Logistics and protection: Pipelines carrying Cryofluid are strategic assets; losing supply from reactors, reactor explosions, or heavy turret output drops can be costly. Protect exposed Cryofluid conduits and storage — Force Projector can be used to shield vulnerable sections from aerial or drop damage.
• Production and crafting notes: Cryofluid is an important coolant for specialized power generation and for liquid turret ammo. It is produced from Water and is required for systems that specify liquid cooling rather than generic water cooling.
• Historical/trivia: The name combines the cryo- prefix (frost) with fluid. The Cryofluid tile and icon have been modified during the game’s development; the current icon and tile were added and adjusted in past updates. In older versions Cryofluid and Water shared the same turret boost multiplier.

Practical advice: route Cryofluid supply to any turret or factory that lists it as an accepted coolant or liquid ammo, and prioritize protecting long runs of pipe. Use Cryofluid at frontline positions where fire suppression and enemy slowing are advantageous, and reserve Water for turrets that explicitly require it.
