How many GB is Petrichor?

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.

Petrichor is a first person horror game inspired by Outer Wilds. Other older games inspired us for the graphics. You are in a cabin in the woods, some strange things are happening here.
