Samurai Warriors 4 (戦国無双4, Sengoku Musou 4) is the fourth main entry in the Samurai Warriors series. Plans for its development was first revealed on Hisashi Koinuma's Twitter and its console availability was later announced at SCEJA Press Conference 2013. The title is being made to celebrate the series's tenth anniversary. Unlike past Samurai Warriors games, this one only has Japanese voice overs.
