Watch the forest change.
See trees, deadwood, weather, animals, human disturbance, and fruiting bodies—the visible consequences of what your network is doing below.
AN INDEPENDENT BIO-STRATEGY GAME
Become the hidden fungal network beneath a living forest. Grow through contested ground, exchange resources with trees, negotiate with other fungi, and decide what kind of ecosystem remains after you win.
OFFICIAL GAME ART / TITLE MARK
A calm but sharp territory-control game played beneath the forest floor.
The forest is not scenery. Water moves through real terrain. Nutrients recover with the seasons. Trees remember whether the relationship has been reciprocal. Rival fungi can be fought, pressured, negotiated with, or allowed to remain.
Connection over conquest?
See the forest from above, plan your network across it, then enter the pressure and conflict inside one patch of ground.

See trees, deadwood, weather, animals, human disturbance, and fruiting bodies—the visible consequences of what your network is doing below.

Grow a connected network, manage water and nutrients, and choose where to apply pressure, where to compromise, and where to live in harmony.

Guide your network through a living fungal battlefield where every route, loss, and captured site changes the wider forest.
Textures, structures, and living patterns guiding the world beneath the forest floor.








You can build treaties, connect tree networks, share resources, and preserve living relationships. Or you can force control, sever routes, and take what the forest offers.
The real question is what remains when the conflict ends.
Ground changes gradually instead of flipping between simple owners.
Water and nutrients move through connected tissue—and rivals can cut the flow.
Trees and other neutral mycelial factions can become independent allies or obstacles.
The battlefield remembers what survived, what was damaged, and who still holds ground.
[ The Mushroom Underground ] is a playable prototype, not a finished promise. The forest, network strategy, and real-time conflicts are working as connected layers while the systems between them are being refined.
See the terrain and the visible consequences of the network below.
Grow, reinforce, digest, and manage a connected network over monthly turns.
Enter contested ground and resolve pressure in real time.
