How many GB is Phobos Project?

3 GB

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

Leave at least 9 GB free: games need headroom to unpack updates.

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

Phobos Project is a first-person psychological horror adventure exploring the depths of psychological horror. In this experiment you have to find a way out and keep your sanity level up through different hostile environments. Face your dread and try to find the source of the nightmare!
