Samurai Warriors 4-II (戦国無双 4-II, Sengoku Musou 4-II) is the revised edition of Samurai Warriors 4. Its sales pitch is to present the "perfect version" of the title, words which are reminiscent to Chronicle 2nd's marketing. The producer adds that it is "another side" of the same game, neither a continuation nor a Xtreme Legends expansion. It is the last title to celebrate the series's tenth anniversary.
