The Sengoku period of Japanese history: a century of civil war, shifting alliances, and military campaigns that left no territory permanently secure. Oda Nobunaga spent his life pursuing what none of the other warlords could sustain: the unification of Japan under a single authority. The player can begin as Nobunaga or choose from any of the era's regional daimyos, each starting from their own position on the map with their own strengths and the problems that come with their particular situation.
