Each player plays one Samurai. The Samurai have a total of 7 lives, shared among all players. A Samurai that is lost or badly injured may be replaced in between waves. Samurai restore their resources in between each wave, but do not recover Body damage or repair damaged equipment.
This item presents limited character creation rules and core combat rules, along with a very simple scenario (a series of ninja wave attacks). It includes four maps and character sheets as print-and-play components. The Version 1.1 document includes corrections and a few clarifications.
