How many GB is Their Navy Is Their Doom?

1 GB

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

Leave at least 7 GB free: games need headroom to unpack updates.

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

Command an advanced submarine in a heart-pounding horror experience as you hunt the last remnants of a defeated enemy beneath the Mariana Trench. Navigate, survive, and uncover terrifying oceanic secrets in this immersive underwater warfare game.
