In 1993 TSR ended production on most of its role-playing game lines, including Gamma World, Marvel Super Heroes, and Basic Dungeons & Dragons, and replaced these soon after with a new universal game system via the Amazing Engine System Guide (1993). In The Galactos Barrier players battle to survive in a corrupt interstellar society. Using advanced technology, and the Music of the Spheres humans and aliens attempt to carve out a home. This book contains the Amazing Engine System Guide as well as a full campaign setting a full colour poster sized map is included. The book is in reasonable condition for its age, there are some creases to the cover (and the remnant of the original price sticker) and there is some foxing to the pages
