Incendiary ammunition



Incendiary Ammunition is a special type of ammo that can be found in Left 4 Dead 2. After picking up this ammo, all gun shots are flammable and can catch infected on fire (with exceptions). Zombies in hazmat suits are invulnerable to incendairy ammo.&#160;The only evidence of this at the moment is a video that can be found here showing up at about 5:49 through 6:49. The video shows an Incendiary Ammo Pile and the effects.
