Helicopter flying/shooting
I'm sure this has been mentioned before but the helicopter forward movement controls are horrible. You should be able to hold forward and maintain your speed instead of rearing up. Or hold shift and forward fly forward quickly without diving into the ground. I'm assuming that's because yall love consoles.
Helicopter guns are absurd. Round impact doesn't have to be anywhere near an enemy to kill them. Hell I'd love to know the kill radius just for a laugh.
I'm sure you made it like this because the controls are horrible so fixing that's probably a good place to start.
