In 1996, humanity has advanced to Mars. However, the Glados Empire, which considers Earth to be in danger, decides to invade Earth, plunging the planet into its greatest crisis. Age, a mixed-race child of Earth and Glados, stows away in the Glados fleet. He steals the state-of-the-art SPT, the Reizner, and heads for Mars, where he informs Anna and the others, who have come to the Mars base for a hands-on learning experience, that Earth is being targeted.
