How many GB is Ultimate Starfighter?

1 GB

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

An unknown Alien Race has launched a failed attack on Earth Station Alpha and are regrouping! Fight off the incoming fleets, discover where their ships are being constructed, and launch an assault! If Earth Station Alpha is destroyed, the planet will be lost and humanity exterminated.
