From publisher blurb: AutoHARP Fantasy: Martial Law is an add-on database (drawing upon the Martial Law supplement) for the AutoHARP Fantasy software. The database file includes new combat rules, combat actions, new skills, weapons, armor, combat styles and martial art styles, new talents and new items. Players can now use Martial Law combat in the Combat Tracker which includes new critical tables and attacks by location. There are also new rules for social classes which include random starting money for the character based on their social class. Additional armor information from Martial Law is also included: new armor pieces, armor quality and armor material. The software works under Windows and most Linux distributions. Use the exe file for Windows and the jar files for Windows or Linux - note the jar files require the Java Runtime Environment.
