Expanding Universe: White Dwarf Classic Traveller Articles

An edited and annotated collection of four articles originally published in White Dwarf, presenting additions and optional rules for Traveller campaigns. The series covers skills, poisons and chemical warfare; ship weaponry, artillery and explosives; campaign locations, alien life and robots; and social status and psionics. This edition preserves the articles in their original form rather than using the later revised versions.
