From the back of the book: In the grim future of Waste World, the Shogunate is the mightiest of the megacities. It is also on the verge of total anarchy. Within its titanic walls, six brutal Overlords prepare to lead their clans into civil war. Each Overlord is served by hundreds of thousands of samurai; immortal, reincarnating warriors with incredible martial arts prowess, armed with super-scientific weapons of unimaginable power. You too can join in this deadly struggle...taking on the role of noble samurai, brutal ronin or lethal ninja. The Shogunate is NOT a complete game. In order to be able to play you require access to Waste World: Roleplaying in a Savage Future.
