How many GB is Specimen 13?

6 GB

That is more than the typical Adventure game, which needs about 5 GB.

Leave at least 13 GB free: games need headroom to unpack updates.

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

In Specimen 13 you play as one of five survivors (or a traitor) who find themselves as unwilling subjects in an experiment set on a mysterious island. Alternatively, play as the Specimen and prevent the survivors from escaping through the underground elevator.
