Description

Title

War… war never changes… but your Minecraft world is about to.

Mars’s Fallout Expansion brings the dangerous, apocalyptic feel of the wasteland into Minecraft with new creatures, game mechanics, weapons, structures, blocks, and loot directly from and inspired by the Fallout universe.

This is my first mod, and the goal is simple: make Minecraft feel more hostile, more rewarding, and a lot more post-apocalyptic.

What This Mod Adds

Wasteland Creatures

Mirelurks!

Face off against familiar Fallout enemies, including:

  • Bloatflies
  • Feral Ghouls
  • Eyebots
  • Radroaches
  • Mole Rats
  • Mirelurks
  • Protectrons
  • Raiders
  • And more to come

Radiation System

rad system

The wasteland is dangerous even when nothing is attacking you.

Radiation can build up from contaminated areas, irradiated food, Uranium Ore deposits, and other hazards. Manage your exposure, use protective gear, and keep yourself alive before the rads cook you from the inside out.

Thirst System

Survival is no longer just about hunger.

You’ll need to watch your thirst, collect water, purify it, and think more carefully about what you eat and drink while exploring.
