The flak guns are a Terran invention,in the sense that IN THE PAST CENTURY WE HAVE CREATED THEM.
The pilots were refering to their(Shivans) weapons, and said no f g, no b c, no shields.Weaponry the Alliance now uses.
Of course it should be a Vasudan invention in FS2,that's not to be excluded...
The Shivans were supposed to use beam weapons in FS1.Also,the Moloch was supposed to exist too before its encounter in the nebula(A Moloch class corvette has jumped in,not we have a new Shivan corvette size warship etc.).
Shivan warships are possibly 10.000 years old,I don't know why the ones who entered TV space in the Great War hadn't beam cannons whe the other had beams.The Lucifer is the Lucifer,beam weapons are a must for it.
Maybe when FS1 was developed,programming technology didn't allowed V to put beams for all Shivan warships.
Beam weapons could even be an idea V boys had after making FS1 and put them in FS2.In this case,they were supposed to exist in FS1 too.
Hey,Woo:why the Dallie is "ATT" now?
