Mycelium: Underground Network

Become the mycelium.

Mycelium is a unique strategy game where you grow and manage a living fungal network beneath the earth. Tap to extend tendrils through the soil, connect to plant roots for symbiotic nutrients, and harvest scattered minerals — all while defending against relentless parasites.

GROW YOUR NETWORK
Expand your mycelium by tapping underground to send out new tendrils. Each branch costs energy, so plan your growth carefully. Your network is your lifeline — the bigger it gets, the more resources you earn, but the more you have to defend.

FORM SYMBIOTIC BONDS
Reach the roots of surface plants to establish mutualistic connections. These living partnerships provide a steady stream of nutrients that fuel your expansion. The more plants you connect to, the stronger your network becomes.

SURVIVE THE SEASONS
Spring, Summer, Autumn, Winter — each season changes the rules. Water availability shifts, parasite aggression varies, and resource spawns fluctuate. Adapt your strategy to thrive year-round or risk collapse.

DEFEND YOUR NETWORK
Parasites lurk in the soil, seeking to destroy your nodes. Fight back with an arsenal of abilities:
• Toxic Node — Place a damaging aura to ward off nearby threats
• Enzyme Burst — Unleash an explosive AOE attack
• Hunter — Summon a friendly organism to chase down parasites
• Acid Spray — Shoot fast projectiles with splash damage
• Spore Launch — Send spores to colonize distant areas

A LIVING WORLD
Watch birds glide across the sky in spring, butterflies flutter in summer, owls silently hunt at night, and bats swoop through autumn dusk. Beetles, ants, centipedes, worms, and fireflies roam the soil around you. People wander the surface above — each one unique with their own appearance. The world feels alive even when you're focused underground.
