Infection Plants
by zenostudios
Infection Plants adds deadly plants that spread through the world and convert nearby blocks, with flamethrowers, cures, a gas mask and grenades to fight them back.
What it does
Infection Plants is a NeoForge mod for 1.21.1 that adds plants which infect and consume the terrain around them. Left unchecked, an infected area keeps spreading corruption into neighboring blocks. Players can answer with flamethrowers and purifiers, torch an infection with sustained fire, or cleanse a zone with a tool that targets one infection type or all of them.
Survival play centers on protection. A Cure Potion removes the infection status from a player, a Gas Mask worn as a helmet blocks infection, and an Infection Protector places a safe zone where the spread stops. Infection Grenades throw spread into a crowd, and Infected Arrows carry the infection to enemies on impact. An Infection Scanner reports the infection level of an area, so a player can judge how far the spread has reached before acting.
Infection Plants runs on client and server, so the server and every player need it. It is published for NeoForge only, with version 1.0.0 for 1.21.1 as the latest file, released on 2025-12-07. The code is under the MIT License, and the mod is not open source.
