Interrior and cover art by Clarence Harrison.

Martial Arts Mayhem, Volume Two stands alone, or can be used with 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 the free material already published on The Game Mechanics website and 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 Roleplaying Game, not to replace them.

Martial Arts Mayhem started out as a set of Experiments we posted on The Game Mechanics website. It was so well received that we decided to expand it into a full product. The original free publications have, of course, remained free.

In addition to all the great free material, 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

More of the Game Mechanics' nicely thought-out class-independant martial arts system. The styles in here emphasize more "non-traditional" martial arts, including those dependant on magic, psionics, and firearms to work. This is a very good th [...]

If you liked the first one, you'll like this one. If you're a fan of the movie Equilibrium, buy this for the Ballistic Fist martial arts style. [...]

Overal a good product. I realy like the mix of feats & abilities introduced as well as the new classes. However, I would have liked to have seen real world styles. Still, this is a good alternative for those who may not have liked Blood & Fists [...]

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
