About this game
Mycelium Conquest is a deep biological network automation game where you control a living fungal organism crash-landed on the alien world of Xenoterris. Grow a sprawling mycelial network, build complex production chains, and evolve from a tiny spore into a powerful entity capable of consuming the planet.
Grow or Die
Start as a vulnerable nascent spore and consume alien creatures and local flora to gather biomass. Hunt, kill, and absorb everything in your path across 5 evolution stages -- from a fragile organism barely surviving to a cosmic entity that consumes worlds.
Build Living Infrastructure
Construct biological structures to process raw resources through multi-stage production chains. Decompose organic
matter, refine enzymes, and manage bottlenecks across sprawling factory complexes.
Automate Everything
Design production lines that transform basic resources into advanced materials. Optimize throughput, eliminate bottlenecks, and scale from a handful of structures to continental harvesting operations spanning vast distances.
Defend Your Network
Your growth attracts hostile alien creatures in escalating waves. Fight back with acidic spray attacks and build
defensive structures. The bigger your network, the bigger the threats.
