|In 21th century, there are three main powers on the Earth. The free world and the communist block carried over from the 20th century; the third power is the New Communist Federation. Since a program of denuclearizing was supported by all those powers, the New Communist Federation developed a devastating non-nuclear weapon: the satellite "Raiden". The two other powers competed with the New Communist Federation, developing their own killer satellites, and the danger of total annihilation became once again an issue.|
Seeing no future for the Earth, humans started to colonize other planets. In 22th century, they sent an experimental ship "Septemius 1" to a star six light years far away from the Solar System.

You are Keith McDonnell, a seventeen-year-old crew member of the ship "Septemius 2" that was sent to investigate the strange disappearance. Will you be able to uncover the mystery?
