Gundam Seed, the animated spinoff series that first debuted in Japan in 2003, comes to the GBA in this game, bringing with it a slew of recognizable environments, mobile suits, and story lines from the television show. Twelve playable mobile suits from the series are available to choose from, as gamers go headtohead in TwoPlayer mode, or link up in Versus mode against up to three other GBA players. Two singleplayer modes are also available: "Manual," which allows players to adjust armor and energy gauges to maximize damage or (adjust the game's difficulty) on the fly, and "Automatic," in which these settings are made by the game.
