How many GB is Dawn Sanatorium?

2 GB

That is less than the typical Puzzle game, which needs about 3 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.

A childhood you don't remember arrives on an old film reel. Step into the Dawn Sanatorium — a first-person psychological horror where a projector rewrites reality, a horned figure watches from the dark, and the truth about who you are waits at the very bottom.
