Acid Wasteland
by yoyolee_
Acid Wasteland turns a world into a decaying post-apocalyptic setting, with acid rain, mutated monsters and unusual foods, and it is installed through a datapack.
What it does
The mod is a wasteland theme delivered as a datapack, adding unique wasteland structures to a desolate, decaying world. Acid rain is a constant threat to survival, and mutated monsters meant to test a player's strength appear across the landscape. New foods with unpredictable effects join the survival challenge, and the survival mode is reworked for players who want a harder run.
The mod is server required and client optional: the server must run it, while players may leave it out. It is released under the MIT License and is open source. Files are published for Fabric, Forge, NeoForge and Quilt for 1.21.4 only, and the latest file is 1.2, dated 2025-05-30. Data pack installation is also listed, and a resource pack can be added to the resourcepacks folder for custom textures.
