Mars's Fallout Expansion
by Mars_Crowley
Mars's Fallout Expansion brings a post-apocalyptic wasteland into Minecraft, with hostile creatures, radiation and new weapons drawn from the Fallout universe.
What it does
Feral Ghouls, Mole Rats and further Fallout-style enemies populate the wasteland, and the mod's stated goal is to make Minecraft feel more hostile and more rewarding. Wasteland guns and melee weapons, along with blocks, items, structures and loot, are added for players to fight with. Radiation builds up in contaminated areas, irradiated food and Uranium Ore deposits add further hazards, and protective gear helps players manage exposure before rads take hold.
Survival gains a thirst and water-purification layer on top of hunger, so players have to watch water as well as food while exploring. The mod is built for Forge only, covers 1.20.1 alone, and runs on client and server, so the server and every player need it. The first version was published on 2026-01-28, and the latest Forge file is 0.7.1 for 1.20.1, dated 2026-07-04.
