How many GB is Scary Cave Diving?

4 GB

Leave at least 10 GB free: games need headroom to unpack updates.

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

A claustrophobic first-person underwater survival horror game where you must navigate procedurally generated cave systems on a draining oxygen tank while being hunted by a massive apex predator. Test your nerves in the main exploration mode, or fight back with a harpoon gun in the action-focused Shark Cage mode.
