How many GB is A.A.U. Black Site?

15 GB

That is more than the typical Simulator game, which needs about 4 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.

The consequence of a mission gone wrong leaves you trapped in an endless cycle of nihilistic, man-made hell on earth, with your only option for survival being to trust a stranger’s voice that guides you through the darkest depths of the forgotten, shut-down Yugoslav town of Uzovnica.
