How many GB is Mushroom Simulator Co-op?

4 GB

Leave at least 10 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

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.
