# How to Install Cryogenic Winter in Project Zomboid

> Master the ultimate environmental challenge. Learn how to install Cryogenic Winter and calibrate your sandbox settings for a permanent sub-zero ice age.

## Eternal Frost: The Cryogenic Winter Conversion

**Cryogenic Winter** is a premier environmental total-conversion modification for Project Zomboid that fundamentally re-architects the simulation's climate engine. By eliminating the standard seasonal cycle in favor of a permanent, lethal ice age with temperatures plummeting as low as **-100°C**, the gameplay focus shifts from standard zombie avoidance to the desperate technical management of body heat. Implementing this modification transforms your FREAKHOSTING server into a high-stakes survival challenge where the environment is as dangerous as the undead.

## Strategic Configuration Requirements

To create a cohesive and technically realistic frost-apocalypse, you must adjust several [Sandbox Variables](/games/project-zomboid/how-to-configure-sandbox-variables-in-project-zomboid) to reflect the environmental reality of a frozen world.

<Tabs>
  <Tab title="Environmental Logic">
    * **Erosion Speed:** Set to **Slow (`5`)** or **Disabled (`-1`)**. Rapid vegetation growth is biologically impossible in extreme sub-zero conditions.
    * **Decay Rates:** Increase the preservation timers for food and corpses. The extreme cold acts as a global natural refrigerator, delaying the decomposition logic.
  </Tab>

  <Tab title="Economic Scarcity">
    * **Farming Yields:** Significantly decrease harvest yields. Successful agriculture should be restricted to indoor "Greenhouse" environments with active heat sources.
    * **Water Persistence:** Accelerate the global water shutoff to simulate frozen arterial plumbing throughout Knox County.
  </Tab>
</Tabs>

## Essential Survival Infrastructure

Administrators should ensure the following assets are available to facilitate community survival.

* **Thermal Regulation (Antique Ovens):** These become the most valuable technical assets in the world database, providing reliable heat without requiring a functional electrical grid.
* **Insulation (High-Tier Padding):** Encourage players to prioritize heavy clothing immediately upon spawning. Without high insulation values, characters will succumb to hypothermia within minutes of outdoor exposure.
* **Logistics (Vehicle Heaters):** Maintaining vehicle engines and heater components becomes a critical mechanical priority for any long-distance scavenging operation.

  ### Technical Load Priority

  Cryogenic Winter implements significant overrides to the engine's weather and climate classes. If your server uses other atmospheric modifications or "10 Years Later" map packs, you **must** position Cryogenic Winter at the **very end** of your `Mods=` list in the server configuration. This ensures its temperature logic takes absolute priority over other conflicting weather scripts.
