Irrational Number Line Games have released the free Magnificent skirmish rules.
From their announcement:
Irrational Number Line Games has published Magnificent — a free, system-independent skirmish (27-70 minis total) scenario based on the Shichi no Samurai / Magnificent 7 plotline. Using a distinctive point system and throwing away the standard idea of teams lets the scenario flex for anywhere between 2 and 6 players.
So round up some heroes, head for that village, and beat up some bad guys … unless you are the bad guys.
