How many GB is Don’t Open?

0.2 GB

That is less than the typical Simulator game, which needs about 4 GB.

Leave at least 6 GB free: games need headroom to unpack updates.

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

Don’t Open is a PSX-style horror game about routine that falls apart before your eyes. A normal shift at a taco bar, an empty stairwell, and a persistent knock on the door that's impossible to ignore. Based on real events.
