Samurai Warriors 2: Xtreme Legends (戦国無双2: 猛将伝 Sengoku Musō 2: Mōshōden) was first released on August 23, 2007, in Japan for the PlayStation 2. It is the fifth Xtreme Legends expansion by Koei, and also the first (and only) Xtreme Legends expansion since Dynasty Warriors 4: Xtreme Legends to be released after Samurai Warriors 2: Empires (other Xtreme Legends expansions are released shortly after the release of the original game). It shares the same achievements with the parent game on the Xbox 360. The expansion introduced new characters to the series, including Toshiie Maeda, Gracia and Motochika Chosokabe. Yoshimoto Imagawa from Samurai Warriors: Xtreme Legends returned in the expansion with an updated character design, Katsuie Shibata and Kojirō Sasaki from Samurai Warriors 2: Empires are also playable and have new weapons. Katsuie Shibata wields two hand axes, while Kojirō Sasaki still carries a nodachi, but can now summon an ex-dimensional sword during battle. Because Yoshimoto Imagawa was put back into the game, the previously omitted battle of Okehazama is brought back, and Hideyoshi's Shikoku campaign against Motochika Chosokabe is also included.
A new mode known as Mercenary Mode is in the game. It resembles Xtreme Mode from Dynasty Warriors 5: Xtreme Legends. Playable characters can now be upgraded to level 70; in the original the highest level was 50. Bodyguards can also level up to 30, when in the original 20 was the highest level. Fifth weapons are present in the game, but unlike the first game, the weapons have the same attack base as the original (before, the fifth weapon would have a higher attack base). Some considered it as an "alternative fourth weapon". In Samurai Warriors 2, the highest upgrade is fourth weapons.
In order to play the full functionality of this game the original is required. "Import" selected on the main menu will guide the players though a disk switching process. Xbox 360 players had to download the expansion via the Xbox Marketplace as there is no stand alone disc available in stores. As for the PlayStation 3 and PlayStation Vita players, the game is bundled along with the two other versions of this game (the original and Empires), thus the players are no longer required to use the "Import" feature.
There is a cutscene in the game (Toshiie Maeda's ending) that was censored and different in the Xbox 360 version because it was considered too violent, so the original ending can only be viewed in the PS2 version.
