How many GB is Casting Whispers?

18 GB

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

Sound is your only hope for survival in this first-person psychological horror game. Investigate the mysteries of an apartment block in 1960s America terrorized by a cosmic horror, as you try to save your lost mentor… and yourself.
