Infectionary
by ick_y
Infectionary turns the overworld into a zombie apocalypse, with infection, stamina, thirst and injuries that players must manage while scavenging ruined cities.
What it does
Zombie attacks carry a 15% chance of infecting the player. A zombie hit carries a 15% chance of infection, and once infected, the condition advances through five stages, growing more dangerous at each one; reaching stage five ends with the player dead and returning as a zombie. Natural regeneration is disabled, so injuries must be treated with crafted medical supplies.
Survival pressure comes from stamina, which limits sprinting and combat escapes, and from water, where dehydration brings penalties. Purified water is the only safe source for now, and the author plans contaminated water systems later. Cities are abandoned, roads run through ruined settlements, and supplies are limited, with handcrafted structures spread across the world for scavenging. Survivors are placed in the world, and NPCs do not spawn naturally yet, so they must be spawned by hand.
The mod is client and server, so both the server and every player need it. It is for Fabric only, released for 26.1.2 with the 1.1 file from 2026-05-12, and it is All rights reserved, not open source. Zombie apocalypse play is the intended scope, and the author notes that it is meant to run standalone, without quality-of-life add-ons.
