Hotter Mania
by Gospi
Hotter Mania is a NeoForge world generation mod for 1.21.1 that reshapes savannas, deserts and badlands and adds two new biomes with their own creatures and items.
What it does
Hotter Mania changes the hot land biomes of the overworld. Savannas, deserts and badlands get new terrain and surface features, and two new biomes are added alongside them. Each biome brings its own creatures, items and craftable content, so exploring the warmer regions of a world turns up things vanilla does not have.
The mod is a major update aimed at players who want new locations to explore, dangerous enemies to fight and a new trading group to deal with. Creatures such as the Ominous Crab and the Sand Snake populate the new areas, and the crafting recipes for the added items sit in the regular game menus.
Hotter Mania runs on NeoForge and nothing else; no Fabric or Forge build is published. Files exist only for 1.21.1, with 1.0.1 as the latest file, published on 2026-03-31 after a first release on 2026-03-29. The code is under the MIT License, but the project is not open source.
