Adventure!
A universal RPG system¸ using mechanics similar to Chaosium's Basic Roleplaying: attributes in the 2-20 range with percentile based skills. A short vehicle design and combat system was included (by Russ Heller). It includes basic stats on vehicles¸ weapons of old and new¸ and a short spell and psionic system. The rulebook is 48 pages with a plain tan cover¸ no cover art¸ and fannish interior art. It has a print run of 400 copies. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H. Kim"
