Dynasty Warriors 9 / 真・三國無雙 8 PT40 - 第六章-赤壁大战 （ 赤壁决战） ）支线任务 ( 华语字幕 )

Dynasty Warriors 9 is a hack and slash game played from a third-person perspective with stealth elements. The game revamps the gameplay of the series with the introduction of the open world environment. A traversable map of China is implemented which the player can freely roam on foot, horseback or boat, the game focuses on livable environments such as cities and towns as well as places where large battles take place. The characters' move-set combinations is also revised.[6][7]

The player can invade and infiltrate enemy fortifications with the utilization of a grappling hook. A day-night cycle and dynamic weather system is also featured in the game. Time and weather now change in real time, and enemy vision is affected at night-time or when it is raining. The map will advance in time when main story missions are completed, but are described as having a "high degree of difficulty" which can be lowered by completing associated side missions.[3]

The player can customize and decorate hideouts with furniture bought from merchants. Certain items have different effects; for example, placing a gong in the house and interacting with it will allow the player to change the background music.[8] Teahouses found in the game can advance time and provide food that can be used to temporarily raise the stats of playable characters, such as raising their attack strength or increasing the height of their jump.[9] The game also includes fishing, collecting resources to upgrade weapons and characters, camping, and other recreational events as well.[10]
