Yahoo! I beat the normal boss finally. Got super lucky too. Evaded most of the final boss' missiles until I managed to disable his weapon system
.
If you want to use a beam weapon, you need to have something to cripple the shield room. I actually liked my fire bomb and that breach bomb combo to take out a room
. Once the shield room was destroyed, I could just beam/laser the boss' weapons to death.
For me the second form of the boss was the hardest. He summoned too many drones. I almost lost my *shield room* in that fight but barely beat him and repaired my ship before beating him.
But I got to say that Nisos is probably one of the best ship to fight against the boss since you automatically fire a beam that penetrates the shield and damages the ship.
