The Jovian Moons Event was a three month long military campaign against the Insurrection. Far from the regulations of Earth and the United Nation, the owners of the Mining Corporations came to want to establish their own countries with their own rules, thus spawning the Frieden Movement. The Frieden Movement soon comes to show its colors as it begins to oppress the workers of the corporations and the unions form into the socialist Koslovic Movement.

The great lie untold, the survivors found the forgotten ship, hidden under the ocean in a secret facility and raised it to the surface.
