Dynasty Warriors: Gundam, originally released in Japan as Gundam Musou (ガンダム無双, Gandamu Musō?), is a video game based on the Gundam anime series. It was developed by Koei and published by Namco Bandai. Its gameplay is derived from Koei's popular Dynasty Warriors and Samurai Warriors series. The "Official Mode" of the game is based primarily on the Universal Century timeline, with mecha from Mobile Suit Gundam, Mobile Suit Zeta Gundam, and Mobile Suit Gundam ZZ appearing in the game, as well as a few units from Mobile Suit Variations, Mobile Suit Gundam 0080: War in the Pocket and Mobile Suit Gundam 0083: Stardust Memory appearing as non-playable ally and enemy units. The "Original Mode" of the game also features mecha from the non-UC series Mobile Fighter G Gundam, Mobile Suit Gundam Wing, and ∀ Gundam. A newly designed non-SD Musha Gundam designed by Hajime Katoki is also included.
The game was originally released on March 1, 2007 in Japan exclusively for the PlayStation 3 with the name Gundam Musou. A North American version was released on August 28, 2007, for both the PlayStation 3 and the Xbox 360 under the name Dynasty Warriors: Gundam. Dynasty Warriors: Gundam is the second next-gen Gundam game released in North America, following Mobile Suit Gundam: Crossfire. A Japanese Xbox 360 version was released in Japan on 10/25/2007 under the name of Gundam Musou International. Unlike the Japanese PlayStation 3 edition, Gundam Musou International features both Japanese and English voice overs.
