ACT 3, MISSION 10
In this mission, you have to protect as many ships as possible (translation: huge dogefight). If you want to be dumb, you can sit inside the node until command says there is a supernova. If you wan't to be good like the rest of us, you just slug it out with the fighters. Of course, bombers always first.
For the ship (same as mission before), i'd suggest the GTF Perseus. it fast enough to engage the enemy quickly, so you can escape to the node before the supernova without having to kill 30 fighters that WERE 4k away. For the weapons (also same as before), GTW UD-8 Kayser and GTM Trebuchet.
