The Titans launch a new offensive against the space colonies of Side 2, where the AEUG enjoys strong support. Side 2's civilian leaders attempt to surrender, but the Titans are intent on carrying out a poison gas attack to teach the rebellious colonies a lesson, and the Argama and its mobile suits are the only ones who can save millions of innocent people from being massacred at the Titans' hands.
But if they use gas on us,
ten to twenty million people could perish!
Le gaz va tuer des dizaines
de millions de gens !
