High Octane

An expansion for Risus that adds more detailed character-creation options and genre-specific rules. It provides numerous Clichés, each defined by a name, dice value, and scope, along with notes for swords-and-sorcery and science-fiction settings. Optional rules cover traps, spells, weapons, modern-era play, NPCs, and locations.
