The Imperium is being torn apart by the star-spanning Rebellion; rival leaders are fighting for the right to sit on the Iridium Throne of the Third Imperium and to rule the greatest interstellar empire that the galaxy has ever seen.
Now, the Rebellion Sourcebook provides the details of the rebellion that allow MegaTraveller referees and players to incorporate the sweep and the chaos of the Rebellion into their own role-playing adventures. Maps show the Imperium and its battlegrounds. Diagrams show the organization of the Imperial military, naturally the source of the armed forces for every faction of the Rebellion. Drawings show typical Imperial military hardware-the Imperial standard design grav tanks, grav APCs, and the typical ships of the Imperial fleets.
The rival factions of the Rebellion have their own distinct leadership, aims, and backgrounds; the Rebellion Sourcebook provides this material.
Also included in this sourcebook is an adventure set against the chaotic sweep of the Rebellion: A starship crew must travel across parsecs of disputed and dangerous territory in a quest for vital starship repair parts. And completion of the trek to an Imperial naval depot is vital to the survival of the Spinward Marches
