Flamethrower

This gun fires a stream of flame by igniting a tank of napalm. The longer you fire the hotter it gets. The highest a normal one can get to is blue. The tanks can run out of napalm, but you have infinite tanks, so you only have to reload. It causes burn damage.

Cost: $25,000.

Possible Upgrades (In the Future)
White-Hot: $10,000. Increases damage if both fire and burn damage.

After-burn: $10,000. Increases time of burn damage.

XL Tanks: $10,000. Increases size of tank, so you can shoot longer.
