How many GB is Oppcium?

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.

A sentient alien organism has escaped its cage and now freely roams a government facility. Silence has engulfed the city as a toxic and unidentified cloud was released from black oily stones. Witness and investigate a dire situation that appears to escalate by the hour.
