Unfun is a Fabric mod for Minecraft 1.21.4 that makes the game deliberately less enjoyable through combat and skill changes.

FabricClient and serverAll rights reserved1.21.4

What it does

Unfun adds dismemberment combat, where hits can sever parts of a target, and four new skills that level up through mining, fighting, crafting and building. Skill progress is tied to ordinary play, so the changes apply across a whole world rather than in a single menu.

Carving, chiseling and casting produce tools, and max-level villagers can trade tokens items. The author describes the mod as a set of additions meant to worsen the gaming experience, and it is set up as a joke or challenge rather than a balance pass. Installation needs Fabric API on Fabric, and the mod runs on client and server, so the server and every player need it. Unfun is published only for Fabric, for 1.21.4, with version 1.0.1 as the latest file released 2025-03-18. The code is not open source and is released as All rights reserved.
