Nioh: Defiant Honor is an add-on for a hardcore action role-playing game with a third-person view in the Japanese style. In it you can see how the Toyotomi and Tokugawa clans will collide in the battle between Osaka Castle and the Sanada-maru fortress. The main character of Nioh, William, heads to Sanada-maru, along with the samurai Masamune Date, who supports Ieyasu Tokugawa, the de facto ruler of Japan in those years.
The add-on requires the original version of Nioh.
