Not only should we add a small fraction to the perk multiplier for wheels down, we should make those perks exchangeable for a universal firepower variant. We could borrow it from Doom and call it the BFG-9000. That, and I'd like a special "zero grav" power up that I can buy when I'm in midflight with some kind of keystroke or cockpit pick. It'd be good to have a whole series of these kind of power-ups, like, for example, "invisible ac, shoot around corners, designatable missile, smokescreen cloud, etc."
What?
haaaw, haaaw...
