Samurai Warriors 3[b] is a hack-and-slash video game developed by Omega Force and published by Tecmo Koei for the Wii.

Like other games in the series, the game reinvents the story based on the Sengoku period of Japan, a period where Japan was ruled by powerful daimyōs and where constant military conflict and much political intrigue happened that lasted from the middle of 16th century to the beginning of 17th century.

The treasure box edition includes the controller as well as a mini figure, an original soundtrack CD and a book with strategies and artwork.
