Perhaps the simplest way is to develop it from the Stargazer. You can get the Stargazer by combining an 0 Gundam (developable from the Phoenix Zero) with an M1 Astray (deveopable from the ORB combat helicopter).
@@danikk04thanks for the tips! I'll do so! Just got this game a few hours ago and still learning the tricks around, was this close to just playing through the seed destiny story until I see strike freedom and fill the GET bar to buy him 😂😂
