3969 MB Gundam Musou Special (ガンダム無双Special) is a video game based on the Gundam animated 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,[2] 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. Adf program. 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. Differences from previous Dynasty Warriors games Dynasty Warriors: Gundam follows in the style of previous Dynasty Warriors games as an action-oriented hack 'n' slash with some tactical elements.

The biggest difference between Dynasty Warriors: Gundam and Koei's Dynasty Warriors series is the core content; rather than using characters and story from the novel Romance of the Three Kingdoms, the games draw their material from across the various Gundam anime series. There are also numerous changes in actual gameplay. The player is given more ranged combat options than in other Dynasty Warriors games, although melee combat is still the main focus of the game.

Characters in Dynasty Warriors: Gundam are also much more mobile, using the Gundam's thrusters to dash, jump in mid-air, and (for some mecha) even fly. Modes of play The single-player mode of Dynasty Warriors: Gundam is divided into two sections, Official Mode and Original Mode. Official Mode features six playable characters in stages set within the continuity of the Gundam Universal Century timeline. More specifically, they are events taken from the original Mobile Suit Gundam television series and its sequels Zeta Gundam and ZZ Gundam.

Original Mode, by contrast, features an original, non-canonical storyline in which teams of mobile suit pilots composed of the three aforementioned Universal Century series and three alternate universe series (G Gundam, Gundam Wing and Turn-A Gundam) investigate a mysterious planet headed on a collision course with Earth; however, the story behind Original Mode is almost the same as the crossover manga Mobile Suit Vs. Gigantis' Counterattack, only with Musha Gundam replacing Gigantis (or Ideon in true case).

In both Official and Original Mode, some characters will switch from one mobile suit to another for certain stages. Depending on the mode, player's can choose pilots and mecha independent of each other, allowing the ability to use any combination of man and machine. Completing a character's Original Mode will allow the player to replay any of the stages from that character's Official Mode using any unlocked mobile suit. Certain characters can be unlocked in original mode only by completing another original mode character's story. Something that long time Gundam fans will appreciate is Official Mode's 'Outcome feature'. The outcome feature gives you the chance to save or spare certain pilots or allies of their predetermined deaths, for example: Saving Emma Sheen before her Mobile Suit is destroyed or too damaged will allow her to be involved in battles that she originally would not have been a part of (like Emma joining the Drop on Jaburo instead of staying on board the Argama).
