Continuing the SD Gundam line of strategy games originally began on NES, this Gamecube update works in a mix of action and simulation elements. During the simulation parts, you move units around on a gridded map in an attempt to increase your territory. When your unit ends up on in the same spot as an enemy, you enter into battle with full control over your Battle Suit in fast-paced action in one of two viewpoints (2D overhead or 3D direct view).. The single player story mode has you follow a series of scenarios as you work through battles. Mutliplayer mode has support for up to four players, although you can go up directly against three computer opponents if you like. In multiplayer mode, you and your opponents set up an original team prior to battle.
