1994 (2nd edition) Macho Women with Guns (MWWG) is a comedy role-playing game originally created by Greg Porter and published by Blacksburg Tactical Research Center (BTRC).

Macho Women with Guns is set in a near-future America where society has collapsed due to the misdeeds of the Reagan administration.

Taking advantage of the earthly chaos, Satan has dispatched her female minions, the Batwinged Bimbos From Hell, to rebuild society in a form she approves of.

The Vatican has responded to Satan's plans by dispatching its elite group of warrior nuns, The Sisters of Our Lady of Harley-Davidson to combat the bimbos.

Dimensional warps caused by the conflict have opened connections to a series of parallel universes, each of which represents a different genre environment such as fantasy, Lovecraftian horror or science fiction.

The first, Batwinged Bimbos From Hell (ISBN 0-943891-08-6), introduced key background details of the Machoverse, as well as rules for aerial movement.

The second supplement, Renegade Nuns on Wheels (ISBN 0-943891-07-8), featured more information about the campaign setting, and rules for ground vehicles.

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 an additional adventure (ISBN 88-86149-08-5) and in 1996 Qualitygame released a small "Pochettravel EditionTM" with the MWWG original rulebook only.

[6] In 1994 Brazilian game company Devir Livraria Limitada released a Portuguese translation (Porter 1994b) titled Mulheres Machonas Armadas até os Dentes [Macho Women Armed to the Teeth].

[10] In August 2003, Mongoose Publishing produced a D20 System version of Macho Women with Guns (ISBN 1-904577-33-4), written by James Desborough and Nathan Webb.

Three supplements (only available in PDF format) are available for the D20 version of the game: Macho Women with Guns - Diet Edition, Adolf Hitler - Porn Star, and The Sex Presidents.
