six-sided dice, but four-sided and three-sided dice may be needed for some rolls. A signature mechanic of Macho Women with Guns is the Macho Attack, which allows a player character to intimidate their enemies with a display of raw charisma by making a roll against their character's Macho score. The opponent then rolls against their Macho score (with modifiers determined by the player character's roll). An opponent who fails their Macho roll is temporarily stunned by the player character, and unable to act. History The original Macho Women with Guns was designed in 1988 by Greg Porter, owner of BTRC, in a period of less than two-weeks. The 12-page booklet was published in August of that year, and became BTRC's most popular product. The following year, BTRC released two supplements written by Porter. The first, Batwinged Bimbos From Hell (), introduced key background details of the Machoverse, as well as rules for aerial movement. The second supplement, Renegade Nuns on Wheels (), featured more information about the campaign setting, and rules for ground vehicles. Especially in the vehicular damage system, it parodied the flow chart-approach of Renegade Legion's Interceptor. BTRC also released a slightly-revised version of the original rule booklet (), which included cross-references to the new supplements. Although the inside cover of the revised booklet identifies it as "Second Edition, May 1989", there were no major rules changes. (Few, if any, gamers acknowledge this booklet as a different edition.) Porter's collection of adventures for MWWG, The Final Chapter (Part One) () was published in 1990. In 1994, BTRC published a 70-page softcover book entitled Macho Women with Guns (2nd Edition) (), which combined and expanded material from the four earlier books (Porter 1994a). It was supported by a single collection of adventures published in 1995, More Excuses to Kill Things. () BTRC has not published any new MWWG material since 1994, but eight other game companies have produced products under license from BTRC. The first licensed products to appear were translations for overseas markets, some of which added new material. In 1992 Italian publisher Granata Press published Maschiacce armate pesantemente [Heavily-Armed Tomboys] and the two supplements SuoCeR - Suore Centaure Rinnegate and PAPI - Pupe con Ali di Pipistrello dall'Inferno on its role-playing games magazine Kaos, with new artwork by famed comic artist Giuseppe Palumbo and Romeo Gallo. In 1995 Nexus Editrice collected them in a book together with
