Star Frontiers / Sternengarde

A space-opera game¸ set in an original universe where four allied races (humans¸ amorphous Dralasite¸ simian Yazirians¸ and insectoid Vrusk) are threatened by the evil worm-like Sathar. It uses a percentile skill-based system¸ where chance is listed separately for each skill (i.e. setting charges is 30%+10*skill¸ while removing security locks is 70%+10*skill). Character creation is purely random-roll attributes¸ however: starting characters have no skills. The second edition retitled the original boxed set ""Alpha Dawn"" and added a ""Knight Hawks"" boxed set with starship construction and combat rules. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H.
