How many GB is Pathogen X?

15 GB

That is more than the typical Shooter game, which needs about 8 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.

An atmospheric first-person survival horror game in which you take on the role of Special Agent Aiden Clark and embark on a deadly mission into an underground laboratory to destroy a biological threat and extract a pathogen sample.
