Obviously, the ninjas if caught on the battlefield, would probably be slaughtered outright.
However, here, I'm looking for some good rules for running a castle assault, probably at night, by a small, or large unit of ninjas, seeking to kidnap, or assassinate a leader.
Ideally, they'd have colorful, effective, and dynamic rules for man-to-man combat, or with several ninjas vs. a samurai. Need rules too, for sneaking about, climbing castle walls (detailed or abstracted), darkness, hidden movement, random guard patrol encounters, etc., etc.. Perhaps some simple, abstract rules for combat too, on some occasions, to keep things moving along. It would be nice if there were also different stats and rules for the various weapons the ninjas can employ: smoke bombs, pepper bombs, blowguns, arrows, shuriken, sai, swords, poison-tipped weapons, etc., etc..
I fondly recall the old videogame I used to play on this subject, so thinking about doing it with minis.
Is there anything like that available for miniatures?
