I hate the Helicopter boss fight so much.
I've watched the oil rig run by "The Pal Professor / @ProfessorPenking" (Good channel btw)
And I noticed something about the boss fight
This boss fight is so stupid.
Tanky as hell.
Position itself on high elevation so that your weapons suffer from damage fall-off.
Non-existence telegraphed attack (Near hit-scan attack with the machine gun and this bomb dropping attack that's near impossible to dodge like it can hit you even when you get into cover)
If you don't have the multi quad launcher. You're basically f-ed.
I would rather they summon Xenolord as a boss fight than fight this thing. It's boring as hell.
