About Mycelium

Mycelium - about the game
Turn-based RPG Mycelium drops a band of wanderers into an ancient cave system amid endless war between rival capitals. Diverse characters with clashing motives push to escape, chasing glory, wisdom, and treasures that claim many lives. Story events reshape mechanics, while your strategic choices sway character fates and forge relationships through battle actions. Defensive battles put enemies in control, with your squad at risk of unconsciousness after just three hits. Manage the group carefully to endure, unlocking unique abilities via quick mini-games for spells, lockpicking, or lute playing. Strategic indie RPG fans who relish intertwined narrative decisions and tense survival tactics will thrive here.

A fungus, a forest and all the time in the world
You are a spore that has landed deep in the forest floor. Grow into the soil next to your network, one tile at a time. Every step costs a little energy; fallen leaves, water and the trees you meet give it back. Reach the surface, wake the barren ground and bloom mushrooms in the grass until the whole forest is in flower.

There are no timers: the forest only moves when you do.
Features
  • Six forests to grow in: Autumn Woods, Spring Meadow, Frozen Pines, Sunbaked Dunes, Misty Bog and Ashen Slopes, each with its own soil, weather and trees.
  • A living underground: 41 kinds of fallen leaves with their own powers, water to drink, poison to avoid and rock to dissolve, with vaults hiding 60 ores and gems.
  • 82 critters sleep in the soil, 47 of them in one forest only. Find them all for your Collection.
  • Link with the trees: reach a tree's roots and its canopy wakes the ground beneath it.
  • Adapt as you grow: every few mushrooms, choose one of three adaptations from a pool of 17.
  • The Grove: every finished season earns mulch for lasting upgrades. Fill your field notes with 36 goals, win 13 trophies and unlock 30 mushroom caps.
  • Five difficulties, from a small, gentle Cozy floor to a Colossal forest with twenty trees.
  • Days and nights with stars and fireflies, falling leaves, petals, snow and embers, and calm music.
  • Mouse or gamepad, on PC or Steam Deck.
