The Searchers of the Unknown RPG Collection

This free collection gathers roleplaying games based on a minimalist old-school rules framework. Characters are defined by a single monster-style stat block, with actions resolved using attributes such as armor class, level, movement, hit points, attacks, and damage. The collection includes the original rules, expansions, and variants covering fantasy, modern-day, science-fiction, and post-apocalyptic settings. Individual games are presented separately and retain their original authorship and content.
