How many GB is Moon Mystery?

25 GB

That makes it bigger than 83% of Shooter games we have measured.

The median Shooter game needs 4 GB; the largest tenth start at 40 GB.

Leave at least 35 GB free: games need headroom to unpack updates.

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

Moon's haunted. No really. Figure out what happened up there, unravel the moon’s mysteries, and uncover why we really raced to land on its surface in 1969. Fill up on oxygen, load up your guns, and set out on a celestial FPS investigation that starts on the Moon and leads across the universe.
