Addon: Ice Age

Ice Age expands survival with a personal temperature system and a world that never fully escaped the Pleistocene cold. Temperature changes according to biome, altitude, time, rain, thunderstorms and nearby blocks. Water, powder snow and ice cool the player, while lava, campfires and other heat sources provide warmth.

There are several temperature states. Mild cold slows movement, but prolonged exposure eventually causes freezing damage. The system is designed to stay unobtrusive in ordinary areas and become important when players enter cold regions without shelter or equipment.

Mammoths provide hide for warm capes. Two base cape types can be combined with chainmail, copper, iron, gold, diamond or Netherite chestplates. Higher tiers improve durability and defense, while the warmth depends on the mammoth hide rather than the armor material.

The addon introduces active and pale thermokarst ponds inspired by thawing permafrost. The active variant contains shallow water, moss and sparse vegetation. The later pale stage is drier, more exposed and colder. Prehistoric animals and the unusual landscape make exploration part of the survival challenge.

This is a pre-alpha release. Additional creatures, frozen methane lakes, tundra and boreal regions, plants and deeper climate systems are planned, so mechanics may change as development continues.
