Prime Directive Modern Edition Supplement

This supplement expands the setting with additional species, factions, and background for the Federation, Klingon Empire, Andromedan Invaders, Inter-Stellar Concordium, Seltorian Tribunal, and other powers. It includes playable and encounter-ready species, new details for constructing adversaries, and story material involving extinct or surviving civilizations. Unified weapons charts collect equipment from the core rulebook and three sourcebooks, while a complete index helps locate rules and gear. Compatible with modern d20 roleplaying systems and requires the Prime Directive PD20 Modern Core Rulebook; the other sourcebooks are recommended for full weapons coverage.
