Fallout Protocol
by GalmUI
Fallout Protocol turns the Overworld into a devastated wasteland, with radiation exposure, rare oasis pockets and a spawn bunker for NeoForge on 1.21.1.
What it does
Fallout Protocol is a gameplay and worldgen mod for NeoForge on Minecraft 1.21.1, and its only published file set targets that version. Terrain generates as an eco-collapse Overworld, with vegetation stripped and the ground sterilized during worldgen. Exposure builds up over time in unsafe conditions, and rare oases and sheltered areas offer places to recover. A simple bunker is generated at spawn, so new players do not start in the open radiation zones.
Radiation rate is set by a base value with separate multipliers for indoor and outdoor areas, and the dose depends on time spent exposed. A full set of protective armor suppresses radiation effects while worn, but the armor itself takes durability damage over time, so heavier armor lasts longer. Shielding blocks can be used for an optional hardened shelter behavior, and the rates are configurable. The mod is intended for use alongside heavy worldgen mods, and the included world preset can be layered in gradually.
The mod is released under All rights reserved and is not open source. The server and every player need the mod installed.
