Flamethrower

The Flamethrower costs $300,000

The Flamethrower has 50 bullets in a mag and has 5 mags to reload with being 300 bullets total.

The Flamethrower is in no way similar to those used in WWII or in modern day. If you put Fire Ammo on the Flamethrower the duration of the fire does not double and the damage does not change. Ice Ammo oddly works with the Flamethrower so the enemy can be frozen and on fire. In the Army the Flamethrower was made illegal to use in combat since the wind can make the flame hit friendly units but it is still used to clear out woodland areas. Just like the Ray gun instead of it being a mist it is a bullet.
