Mushroom Simulator Co-op

You're a mushroom. Your friends are mushrooms too. Grow big, enjoy the rain, watch out for worms and the forager with a basket. No quests, no bosses. Just you, the forest, and that worm that crawled up at the wrong moment again.

About the Game

It's a world where you're a mushroom and so are your friends

SPEAK AND GROW

Voice waves magically feed your mycelium, speeding up your growth. Got a hedgehog eyeing your cap? Yell at it, and it'll realize it messed with the wrong mushroom - but be careful: noise can draw unwelcome guests, so sometimes it's best to shut up...

STAY QUIET AND SURVIVE 

When a forager with a basket walks into your clearing, your only chance is to pretend you're not there. One sneeze and all that's left of you is spores.

PICKED? EATEN?

No big deal - scatter your spores and start fresh. Mushrooms never give up!

PLAY WITH FRIENDS

Get random mushroom skins, find your spot in a cozy clearing, and survive together with friends. Along the way you'll meet strange creatures and learn to accept yourself for who you are.

No quests, no bosses. Just you, the forest, and everyone who lives in it.
