How many GB is Spacerift: Arcanum System?

5 GB

Leave at least 11 GB free: games need headroom to unpack updates.

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

At the sunset of human life on planet Earth, you are a military pilot controlling a space ship, and you find yourself at the very epicenter of the battle in the solar system. You are forced to retreat into the unknown, distant Arcanum system through hyper-jumping.
