Guns! Guns! Guns! (2nd Edition)

A firearm-design toolkit for role-playing games. Players create custom weapons in a universal format, then convert their statistics to the game system of their choice. Step-by-step design sheets cover conventional firearms, rockets, lasers, particle beams, railguns, and other weapon types. Designs can be created for any technological level at which the weapon could exist, including alternate-history combinations such as Roman machine pistols or World War II lasers.
