From publisher blurb:
Kumite is a collection of rules to help GMs and players run martial arts inspired action adventures. This game was inspired by movies like Karate Kid (1984), Big Trouble in Little China (1986) and Bloodsport (1988), as well as other martial arts RPGs and video games.
Although planned for use with ICRPG, the ideas and adventures here can be easily adapted to other games, including OSR titles.
In this version Kumite you will find:
Setting-specific Rules for Martial Arts Action
Character creation for powerful martial artists
Rules for the use of Chi and 20 martial arts techniques
Stats for thugs, warriors, elite warriors, enemy bosses, and mystics, all of them customizable with exclusive special abilities
100 LOOT table for martial arts action
3 adventure lay outs that form a continuous mini-campaign
