How many GB is Subterror?

1 GB

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

Leave at least 7 GB free: games need headroom to unpack updates.

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

At the bottom of the ocean floor lie The Biospheres. These weather-controlled domes once supported vast arrays of lifeforms, but have since been abandoned. Explore arid deserts, dark forests, and frozen tundras. But don't stay too late, as you are not alone out in the great abyss.
