Normal missions can be unlocked by completing certain scenario missions. Scenario missions follow the anime plot whereas normal missions are interventions not shown in the anime. There are two types of missions: scenario and normal. Each of the pilots have an advantage against their home nation except for Tieria who has a small advantage against each bloc. The aim of the game is to deplete the military strength, represented by a health bar, of the three nations which dominate the world: the Union, Advance European Union and the Human Reform League. Players are able to choose a Gundam Meister of their choice, with a gundam that may be suited for the mission. Then, players choose a mission to accept. Starting off with the setting, players will commence dialogue and retrieve information to continue the plot although this is optional and can be skipped. There are four main parts to the gameplay: discussion, mission choice, getting ready for battle, and mission itself.
