How many GB is Heliophobia?

12 GB

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

Leave at least 20 GB free: games need headroom to unpack updates.

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

Heliophobia is a first-person horror/mystery adventure presented through a surreal, non-linear narrative. You awake on a vacant plane, given only a singular task: kill the one with the initials "J.R.".
