How many GB is Underground?

0.49 GB

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

Leave at least 6 GB free: games need headroom to unpack updates.

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

Underground is an independent FPS horror game that immerses you in a vast network of dark, labyrinthine caves. You play as a spelunker lost in this terrifying expanse. Your objective is simple yet nerve-wracking: find the only exit before the situation becomes fatal.
