How many GB is Psycho-Sleuth?

10 GB

That is more than the typical Strategy game, which needs about 3 GB.

Leave at least 17 GB free: games need headroom to unpack updates.

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

Psycho-Sleuth is a psychological mystery where cognitive disorders twist the logic of murder. 13 afflicted participants — each bound by strange rules like “no lying,” “no left side,” or “no faces” — are trapped in a deadly game where the sickness spreads and truth itself becomes unreliable.
