I'd like to know what they produced at Gigas Fossae before the Schizm on Mars but i cant find any solid hints to that.
They had some fancy plasma reactors which were targeted as a test of the unit targeting them but i don't feel like that's enough of a hint to conclude that they produced either very good plasma reactors, very good shield emitters or particularly capable armored structures.
Solid info is wanted, but opinions on this minimal info are very welcome too.
