[Series] X Universe

Release: Jul. 1999

Set in 2912, you assume the role of Kyle Brennan, an Earth test pilot for the X-Shuttle, which has the ability to jump across space through a wormhole rather than relying on man-made jumpgates. During a test flight, something goes wrong and Ken ends up in an unknown part of the universe, where a alien race, the Teladi, fix his ship and make him take up merchant routes to pay off a debt to the aliens. With his jumpdrive destroyed, Ken finds himself lost and stranded in this foreign universe, with no way of getting back to Earth.
