I only added one thing in this patch: An assault rifle that sets your enemies on fire

Pull the trigger while your clip isn't empty? shoots bullets. Pull the trigger with an enemy in your line of sight? Sets them on fire. Every. Single. Time. Even if your clip's dry. The bullets aren't incendiary, the demons just see The Assault Rifle That Sets Demons On Fire and set themselves on fire in a panic. It's a self fulfilling prophecy
