Dynasty Warriors: Gundam offers typical hack-and-slash gameplay from the Koei series, with players piloting Gundam mobile suits instead of Chinese generals. The game follows the third-person battle tradition of the Dynasty Warriors series, allowing players to slice and shoot hundreds of enemy mobile suits per level.
Two different campaign choices are available: one following the series history and another with a new original story. Changes to the series include flying, changing suits between battles, and inhabiting the Gundam universe's fiction.
The Xbox 360 version features action-packed gameplay, while the PS2 port (released on November 9, 2007) includes new scenarios and mobile suits.
