How many GB is Miasma?

2 GB

That is less than the typical Adventure game, which needs about 5 GB.

Leave at least 8 GB free: games need headroom to unpack updates.

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

Miasma is a first-person psychological horror maze game with a horrific atmosphere, you are trapped in a maze-like prison with a mysterious creature, and your only hope of survival is to find a way to escape.
