[1] The book is divided into several sections:[2] GDW first published the space opera role-playing game Traveller in 1977, and many adventures and supplements followed.

Ten years later, in an attempt to revitalize the franchise, GDW revised the rules and published it as MegaTraveller.

A new storyline about the breakdown of the Imperium was presented in 1988's Rebellion Sourcebook, a 96-page softcover book by Marc W. Miller with contributions by Ed Edwards, Joe D. Fugate Sr., Gregg Giles, John Meyers, Mike Mikesh, Marc W. Miller, Jefferson Swycaffer, and Gary L. Thomas, with interior art by Timothy Bradstreet, Rob Caswell, Steven S. Crompton, Liz Danforth, Jeff Dee, Bryan Gibson, Tom Peters, and A.C. Farley, with cover art by Farley.

"[1] In the January 1989 edition of Dragon (#241), Jim Bambra called this sourcebook "solid support for the Megatraveller game.

However, he concluded that this book was "an excellent resource for anyone running adventures in what remains of the Imperium [...] This is another fine addition to the Megatraveller game.
