Deep Winter
by Tlagz
Deep Winter is a NeoForge world generation mod that adds a desolate winter biome with a blinding icy fog.
What it does
The mod adds a post-apocalyptic winter theme through a new biome, DeepWinterBiome, where trees and animals have vanished and only endless snow and silence remain. Players exposed to the harsh cold can be engulfed by DeepWinterFogEffect, an icy fog that blocks vision. Client and server both need the mod, so players and the server must each run it. The 1.2.1 file covers 1.21.4 and was released on 2025-10-14, and the code is all rights reserved.
Key features
Desolate winter biome
A new biome, DeepWinterBiome, offers a frozen wasteland with no trees, animals or life.
Blinding icy fog
DeepWinterFogEffect rolls over anyone exposed to the harsh cold, limiting what the player can see.
Shelter from the storm
Caves and solid structures give players a place to shelter and regain clear vision while the storm passes.
