Samurai Warriors: Katana

Samurai Warriors: Katana, originally called "Samurai Warriors Wave", is the first Koei game released for the Nintendo Wii played with the Wii Remote and Nunchuk attachment. The action is seen from a first-person viewpoint. In battle, the player character is equipped with one melee weapon and one ranged weapon. The player can freely switch between melee and ranged weapons during combat. Attacks are performed through either pressing the attack button on the Wii Remote to attack single enemies, or motion-based attacks that can damage groups.

Outside of combat, there are running sequences where the player must swing his/her arms with the Wii Remote and Nunchuk in hand to simulate the arms pumping in a running motion. Horseback riding is also included, with the Wii Remote performing the function of the reins while the Nunchuk is used as a whip.

The game also includes a competitive multiplayer mode for two players.
