Samurai Warriors 4-II is a hack and slash game and the enhanced version of the original Samurai Warriors 4. It is described as neither a continuation nor an Xtreme Legends expansion like previous games; instead it provides a "different" focus of the same game. Players choose a character as their protagonist for a selected scenario which has a different progression depending on the character selected. Dream Castle Mode first introduced in Samurai Warriors: Chronicles 3 is also present in the game. The game adds one new character Naomasa Ii to the character roster.
