From publisher blurb: Martial Arts Mayhem, Volume Two stands alone, or can be used with Martial Arts Mayhem, Volume One of this modern d20 System martial arts supplement. It's written by Rich Redman, a designer on the original d20 Modern Roleplaying Game from Wizards of the Coast, Inc. Every modern d20 System character can learn a martial art, and now Rich Redman adds depth and options to characters, combat, and campaigns with Martial Arts Mayhem, Volume Two. Building on Martial Arts Mayhem, Volume One, Rich ups the ante with more martial arts schools, feats, secret techniques, weapons, and campaign options. From basic Self Defense to weapon-weilding Kobujutsu masters, Martial Arts Mayhem, Volume Two has something for every modern character and GM! Martial Arts Mayhem maintains the balance between firearms and martial arts found in the d20 Modern Roleplaying Game. We designed it to work with the feats in the d20 Modern game, not to replace them. Martial Arts Mayhem, Volume Two includes: new feats new schools, including those that incorporate psionics and magic new secret techniques stats for martial arts weapons three campaign models complete with NPCs new optional rules
