My god. You'r suggesting Friendly Fire? Much more, but to kill a whole ship with 7,500-8,000 vasudan souls (encluding a few human souls) so you wont get yelled at? I would never commit such war crimes, an unethical behavior.
I saved the Neptuu quite a few times. I took the 'power weapons + kick ass' loadout. Harps, torns, dubble kazers (1\2 of the time i dubbled kayzers) and a single bank of maxim.
Only way to kill abraxis is to treb, maxim\kazer it as much as u can, after killing beam turrets; and then kicking majior bomber ass. Always call in reinforcemtns first thing.
Though i hated this: After it blows, or you save it, you have to haul ass back to Lamda 1. (I'd assign Theta wing to protect it first thing, incase i didnt get there in time.)
Is it just me or are those Lamda xports just asking to be blown up?
