An expanded port for PlayStation 2 called Gundam Musou Special was released on February 28, 2008 in Japan, featuring new scenarios and mobile suits.

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.

[8] Every mobile suit and pilot has their own strengths and abilities, and the player is given both ranged and melee combat options.

[10] Official Mode features six playable characters in stages set within the continuity of the Gundam Universal Century timeline.

Depending on the mode, players can choose pilots and mecha independent of each other, allowing the ability to use any combination of man and machine.

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).

Also, the game sold about 70 percent of its 170,000 -180,000 launch day shipments, making it rank third in overall sales — after Ridge Racer 7 and Mobile Suit Gundam: Crossfire.
