How many GB is DarkStorm?

6 GB

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

Leave at least 13 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 as MARS (Machine of Absolute Retaliation and Safeguard), a robot programmed to exterminate the treacherous aliens who have taken over Razor City. As MARS, you must free Razor City from its domination in order to save the survivors from their doom.
