Kessen III

Kessen III is an action-strategy game and the final known Kessen title. It implements gameplay elements from the Warriors series and the longest title of the three. The game claims to recount the history of the Samurai Warriors characters (a similar notation was also made for Saihai no Yukue). In the game's manual, the producer gives the following foreword:

''"Kessen III" represents a new style of game play, standing at the confluence of Action and Strategy geners, which unifies the worlds of interactive entertainment and cinema. May you be carried away in the excitement of battle and the thrill of commanding legions of your own troops in your quest for peace and power.''

Nobunaga Oda is the uncommonly heroic protagonist with a sincere ambition to end the land's chaos. He and his generals visually age as the game progresses and adopt a new attire various times throughout the game. As time passes, Tokichiro and Motoyasu will also be called by their recognizable historical names.

It is the only game in the series to include a dual language option, allowing the player to switch between the English and Japanese voices.
