How many GB is The Invasion of Area 51?

3 GB

Leave at least 9 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 the last man standing in an alternate take of the Area 51 raid where you must hold off the endless waves of civilians. You have an assault rifle, access to top-secret government weapons, and endless supplies to keep you stocked.
