How many GB is Operator: Observation?

15 GB

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

Leave at least 23 GB free: games need headroom to unpack updates.

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

Operator: Observation is a Game based on the "Watch Rooms, and Report Anomalies" Concept of "Observation Duty" but now the Anomalies are way more aggressive and have way more ways to make you lose your Mind. Your Instructor will follow you on the way to becoming a good Operator.
