Gun Overheating mechanic and other more

[gentle geyser]

I like the overheating idea, the A-10 should be used a burst gun, like in real life. Forces you to aim well and hold your fire.
Hardcore sounds cool, but cockpit being an auto kill is a bit too much.

Good call

This all sounds good. I'm working on the new camera system design so will see if I can fit the damage stuff into it
