Actually, Ive come to realize just how wacky you can make guns due to trying to toy with this in my spare time.
And entitre arsenal into one gun . . .
You could likely make a gun shoot ammo that ‘reverts’ to gasoline when dropped. Make it a burst and g2g. but it seems that gasoline is flagged to flame along, so you couldnt use gas as its fuel . . . youd have to maybe make a recipe that ate gas and made ‘trap gas’ to spray the ‘trap gas’ along the ground in inaccurate manners. Then it would turn into proper gasoline.
