Samurai Warriors is a hack and slash series developed by Omega Force and first released in 2004 for PlayStation 2 and Xbox, set during Japan's Sengoku period. As a spin off of Dynasty Warriors, it built its identity around dramatic battlefield music blending rock with traditional Japanese instruments. The defeat track by Michihiko Shichi came from that first game and stayed in players' memory because it accompanied every failed mission. Clips of the jingle later circulated on soundboards and in gaming videos as a shorthand for losing.
