A series of modern d20 System sourcebooks by Rich Redman.

Martial Arts Mayhem is a modern martial arts supplement for the d20 System, available as two PDFs or one print volume. These new rules let players and Gamemasters create martial arts master of any style, from traditional kung fu and ninjutsu to Zen archery and French savate, and even boxers and flamboyant pro wrestlers! No Modern game would be complete without Martial Arts Mayhem!

When you use Martial Arts Mayhem, every melee combat is unique thanks to added customization. Your heroes are no longer limited to the Brawl feat tree, the Combat Martial Arts feat tree, and Defensive Martial Arts. Instead, your heroes can become light-fingered masters of the Deft Touch School. They can confuse and befuddle opponents as masters of Drunken Fighting. Or they can launch powerful, lightning-fast kicks as masters of the Northern Leg School.

And because anyone can be members of these schools, your heroes will never know if the old man sweeping the sidewalk is a mere shopkeeper—or a secret master of Sticky Hands! Even when he takes his combat stance, they cannot be sure whether he knows the Thousand-League Eye technique, or Repulse the Monkey (or both) until it's too late.

Martial Arts Mayhem maintains the balance between firearms and martial arts found in the d20 Modern Roleplaying Game. It is designed to work with the feats in the d20 Modern game, not to replace them.

Martial Arts Mayhem includes:

  • New feats
  • Martial arts schools
  • Secret martial arts techniques
  • Stats for martial arts weapons
  • Campaign models complete with NPCs
  • New optional rules
