Nioh is a 2017 action role-playing game set in a dark fantasy version of Japan's Sengoku period, where players control William Adams, a blonde-haired, blue-eyed English samurai. The gameplay emphasizes challenging combat with a focus on trial-and-error, stamina management, and the use of different fighting stances. William's journey involves fighting hordes of supernatural demons known as Yokai and rival samurai while pursuing the thief of his guardian spirit. The game blends historical events with Japanese mythology, offering a deep and technical combat system with diverse weapons and customizable playstyles, and is often compared to the Souls series in its difficulty and progression.
