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 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.
