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 to reflect the environmental reality of a frozen world.
  • 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.

​
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.
