How many GB is O.B.O.L?

0.24 GB

That is less than the typical Strategy game, which needs about 3 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.

Play a high stake game of head or tails against a mysterious opponent, trapped under the ocean in a claustrophobic, eldritch, Lovecraftian horror atmosphere, all while slowly losing your sanity.
