The game is set in the year 2496 and follows a century-long war with an invading force known as the Kilgethions. A peace treaty is finally signed by the superpowers of Earth and the Kilgethion leaders, although both side still hire freelancers for work that is considered to be outside of the treaty.

Ran is enlisted by an Earth-based fraction to raid a Kilgethion supply chain and steal some very rare ‘booty’ that the lead ship is carrying. During the mission Ran accidentally uncovers a plot by the Kilgethions to attack earth by constructing a battle fleet on the moons of three planets in our solar system.
