A port of this game called Samurai Warriors: State of War has been released for the PlayStation Portable, which includes additional multiplayer features.

Players can find items which affect their attributes through normal battle by defeating enemy officers or breaking open crates.

The value of these bonuses depends on three things: the difficulty level, the stage the player is on and the ranks the character has in the 'Discern' skill.

Samurai Warriors contains a number of changes to Dynasty Warriors' combat system, most notably the ability to perform free-style combo attacks during Musou attack mode, during which the game enters bullet-time; common soldiers move slowly, but officers are unaffected.

Other changes include the ability to perform a roll to dodge attacks, and deflect incoming arrows with their weapon.

The higher the rank and the harder the difficulty setting of the game, the more the player's character attributes will increase.

Success in these missions can be crucial to the outcome of many battles as failure often results in a massive loss of morale to the player's forces.

Samurai Warriors gives players the opportunity to create new characters via the officer training mode.

The game features a total of 15 characters based on historical figures during the Warring States period of Japan, including daimyō Kenshin Uesugi, Shingen Takeda, and Nobunaga Oda as well as other notable samurai such as Yukimura Sanada and Ranmaru Mori.

In addition to the figures who were noted to have fought during the period, the game also made playable a handful of female characters that did not fight in any battles, such as Oichi and Noh.

Note: Hideyoshi Hashiba and Yoshimoto Imagawa were unique NPCs in the original game before they were made playable in Samurai Warriors: Xtreme Legends.

Lu Bu of Dynasty Warriors fame, also appears as an unplayable boss of Survival Mode.

Samurai Warriors: Xtreme Legends extended this further, by adding even more powerful sixth weapons to earn.

A port to the PlayStation Portable, called Samurai Warriors: State of War, was released in Japan on December 8, 2005 and March 7, 2006 in North America.

Other characters who make non-playable appearances are Kunoichi, Shingen Takeda, Okuni and Goemon Ishikawa.

Gameplanet commented that it is "well implemented", allowing players to accurately play a character made for them[37] while GameSpot regarded the option as "a nice touch" but "rather tiresome" in the end.
