Since then, KOEI and KOEI Tecmo have released seven more games in the main series, and numerous spinoffs (including the Samurai Warriors series), with a ninth game slated for February.
Game developer KOEI Tecmo Games filed trademarks for “Baseball Musō,” “Tennis Musō,” and “Soccer Musō” on January 5.
Musō is the series title for KOEI Tecmo Games’ series of hack-and-slash action games, and is titled Warriors in the West.
KOEI Tecmo also released the Warriors All-Stars crossover game last August.
