Fungal Infection: Cataclysm
by Night_Cloud
Fungal Infection: Cataclysm is a Forge mob mod for 1.20.1 that turns the Fungal Infection theme into an organized war against specialized spore creatures.
What it does
Instead of a passive spore threat that spreads quietly in the background, the mod introduces hostile fungal units with distinct roles. One unit digs tunnels and surfaces right beneath a base, another charges at high speed to break a front line, and another fights in the air before slamming back down to the ground. Each creature is built around a specific counter-strategy, so players face a coordinated army instead of a horde of similar monsters.
Installation covers the server and each player's game. Latest Forge file is 1.5.2 for 1.20.1, published on the beta channel on 2026-08-11. The license is All rights reserved. It was first published on 2026-07-21 and has no other game versions in its listing.
Key features
Specialized fungal units
Each spore creature has a defined role, from tunneling ambushes to fast front-line charges and aerial attacks.
Tunneling ambushes
Some units dig underground passages and emerge in places players may not expect, including beneath existing bases.
Aerial slam attacks
Flying units lift into the air and drop back onto the ground, forcing players to respond to threats from above.
Counter-strategy encounters
Each unit type requires a different response, so fights depend on planning rather than repeated grinding.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Defending a base
Tunneling and aerial units can reach areas players thought were safe, so defenses need to cover more than one direction.
Fighting a spore army
Players facing several unit types at once have to adapt their tactics as the fight changes.
Who it’s for: Players who want Fungal Infection to feel like an active conflict rather than a slow survival threat, and server owners who want harder, more varied mob encounters on a Forge 1.20.1 server.
