When it comes to the gameplay of Gundam SEED Advance, it is split into two different types; Battle and Exploration. When in Exploration mode, you can move around the Archangel battle ship and interact with the crew. This leads to “quests” of sorts, as well as just general NPC dialogue. In terms of Battle mode, it is also split into two parts; the Strategy menu before the battle, and then the battle itself.
When in battle, the game switched to a different view point, having a top down view of the map with your Mobile Suit in the middle. A radar on the bottom right shows you the nearby enemy locations, and the GUI in the top left shows your health and energy. From here, you have to fly around and get close to the enemy. Then, by pressing A you shoot out a target lock on system which, if it connects to an enemy, allows you to then press B to attack with you currently equipped weapon. Attacks take the form of two cutscenes; the first shows you performing the attack, whilst the second shows whether the enemy gets hit, and if they do, how much damage they take. This is also the same for when an enemy attacks you, only in reverse.
