Prime Directive PD20 Modern

Roleplaying on the Final Frontier using the d20 modern rules, which work better for Science Fiction than the dungeon-based V3.5 rules.
This is a major redesign of the original PD20V3.5, professionally edited, eliminating the many mistakes of the original dungeon-based version and entirely re-edited for the "modern" rules set. New classes, new skills, new information.
This book requires that you have the d20 Modern rules, which are available elsewhere.
