Samurai Warriors stars the brave Sanada Yukimura, who leads an elite band of samurai and ninja. Sanada's journey will take him to the hallowed Japanese battlefields of Okehazama and Kawanakajima and inside the embattled walls of Osaka Castle where he will come face-to-face with gun-toting troops, echelons of ninja, and deadly kunoichi (female ninja).

Players can choose the role of Sanada Yukimura or other legendary samurai and ninja. The game will herald the rise of the indispensable ninja, Hattori Hanzo, from the shadows of history, as well as the reemergence of KOEI's powerful and mysterious Oda Nobunaga.

Samurai Warriors boasts several new developments. Among them, the new AMS (active mission system) triggers a distinct mission during each battle. To accept or decline the mission is up to the player. Missions evolve depending on player performance and the tide of battle. Success or failure can affect scenarios in later stages. With 500 variations, the chain of missions is unique with each play, adding depth while heightening the urgency and excitement of combat. Samurai Warriors' AFS (auto-formation system) randomly generates castle levels and conquest routes offering a new experience with each play.

Samurai Warriors also features:

• Game environments are rendered in deeply saturated chromatic tones while seasonal and time elements enhance the lush visuals. Cherry blossoms will flourish throughout springtime battlegrounds. While in autumn, the pampas grass will sway.
• The New Warlord mode allows players to create a warrior by clearing a series of mini-games. The results of the mini-game determine the characteristics and abilities of your warrior.
