From publisher blurb:
Sci-fi and cyberpunk campaigns need guns. New guns, shiny and deadly guns. Laser weapons and particle beams, and more exotic things.
The Advanced Arsenal has your back.
The new weapons here are derived from Otherverse Game’s signature campaign settings, minus the setting specific flavor text. Gamers who aren’t interested in the politics or theology behind Otherverse America, or the raunchy 70s-flavored sleeze of Heavy Future can still use some of their coolest weapons in their own campaigns. This sourcebook also standardizes and collects a wide variety of ultra-tech firearms originally presented in several different sourcebooks, and consolidate their information in one place, in one format.
