The Fungal Infection Co Op Base Defense Modpack turns your world into a scary, decaying wasteland where a smart fungal plague grows and takes over the land. You must work with your friends to build strong bases, set up traps, and fight off mutated monsters before the rot swallows everything you have built.

The Fungal Infection Co Op Base Defense Modpack

Features:

  • Dynamic Fungal Spread: The infection slowly eats the terrain and grows over blocks, poisoning you if you touch the infected plants
  • Smart Base Defense: You can build and upgrade your protection from simple floor spikes and slingshots up to heavy cannons and automatic turrets
  • Guided Quest Books: Lost journals written by a survivor named Steve help you learn how to build defenses and stay alive
  • Realistic Early Survival: You cannot chop big trees with your bare hands anymore, forcing you to gather small shrubs first to craft your very first wooden axe
  • Stamina Movement System: Running and jumping drains your energy bar, requiring you to eat food regularly to keep your strength up
  • Custom Post-Apocalyptic World: Explore ruined cities, broken structures, and dead biomes filled with custom survivor NPCs and armored super villagers
  • Deadly Fungal Monsters: Face terrifying new enemies like a flying spore beast that tracks you from far away and shoots through your shield
  • New Underground Resources: Mine unique materials like deep slate lead ore, hanging prismarite, and strange growable redstone plants
  • Lightweight Multiplayer Fun: Designed to run smoothly on low-end computers and cheap co-op servers without lag
