Samurai Warriors: Katana (戦国無双 KATANA, Sengoku Musou Katana), originally called "Samurai Warriors Wave" and "Samurai Warriors Slash", 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 or use both simultaneously. 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. When dealing with enemy officers, players may choose to strike at their weak points or deflect incoming ranged attacks right back at them.
