The dangers of using fire
Just remember fire isn’t a head shot. One its burns but takes a long time to disable the zombie if it does. And most of the time fire will NOT kill a zombie. So always shoot it to be safe. And Molotov cocktails while easy to make are utterly useless because it will draw the zombie to you while it is completely engulfed in flames so it will possibly burn you then zombiefy you. So if you do find yourself in a city, which is HIGHLY dangerous and not recommended by any zombie survivalist, and a large amount of zombies are conglomerating near your location use that to your advantage and go to the roof and barricade the door then use the rooftops to get away from it then immediatly exit the city.
