Set during the Warring States period of ancient China (approximately 475–221 BC), the game places the player amid the struggle of seven kingdoms — Qin, Chu, Qi, Yan, Han, Wei, and Zhao — fighting for control of a fractured land. The Zhou Dynasty has collapsed as a governing force, and the great states have turned entirely to war. The player navigates this era of shifting alliances, military campaigns, and political maneuvering in the hope of unifying the continent.
