Battle of Mt. Dingjun

The Battle of Mt. Ding Jun was a battle between the forces of Liu Bei and Cao Cao. Liu Bei was seeking to control the culturally vital Hanzhong region, as well as open a path into Wei, while Cao Cao was trying to stop him. The two archers Huang Zhong and Xiahou Yuan developed a rivalry here, ending with Huang Zhong and his forces slaying Xiahou Yuan, and driving out Wei.

The series highlights the efforts of the generals Huang Zhong and Xiahou Yuan. In all games in which the battle appears, a small rivalry takes place over the battle between the two. Some installments have them exchange insults during the battle, while others have a cutscene prior to the battle, and when the two generals meet. In the end the player has the power to decide the ultimate victor, although normally if you leave the duel of sorts alone the opposing general to your force will claim victory.
