Hollow Snow
by ketoshi
Hollow Snow is a Fabric survival horror mod in which a winter climate and a cold meter turn staying warm into the main task of play.
What it does
Cold builds up whenever a player stands somewhere that is not warm, and the meter has no cure except heat. Torches, campfires, lanterns and lit furnaces warm the player, and glowstone lights a room. Roofs do not shelter from the cold, and a sword does not fight it, so the player has to build a warm space and keep it fueled.
Winter also reaches the rest of the world. Ordinary crops freeze outdoors, so food needs a greenhouse with glass overhead for daylight. Livestock left in the cold seizes up and stops, and an animal kept warm is the only kind that survives. Ember furnaces, embercore heat pipes, blowers and batteries can carry warmth from one place to another, and a furnace lined with nether brick burns fuel longer once it has been settled in one spot.
The mod requires Fabric API and is published only for Fabric. Installation covers the server and each player's game. Files cover 1.21.8 – 1.21.11, and the latest is 0.4.0 for 1.21.11 on the alpha channel. The mod is released under All rights reserved and is not open source. Horror imagery appears in the content, among it a jump-scare that fills the screen with sound, so players who react badly to that kind of thing should weigh it before installing.
Key features
Cold meter
A cold level rises while the player stands outside heat and drops near a warm source such as a torch or a lit furnace.
Heat sources
Torches, campfires, lanterns, lit furnaces and glowstone rooms count as warm, while roofs and weapons give no protection.
Ember furnace and heat pipes
Charcoal fuels an ember furnace, and embercore pipes, blowers and batteries carry the heat from it to wherever the player needs warmth.
Greenhouse farming
Crops planted outdoors freeze at their first stage, so food is grown under glass with daylight coming through.
Livestock in the cold
Animals left unheated seize up and stop, and only animals kept in a warm space survive the winter.
