This simple mod will allow you to add or remove flashlight. To do this, press "ESC" key and then press the "B" key on your keyboard. If you have the flashlight, pressing "B" at pause menu
will remove it. Pressing the "B" key at pause menu again will give you flashlight back. This mod is purely esthetical and has no practical purpose. It's useful if you want to take screenshot of your character from third person perspective, so that flashlight won't be sticking out of your forehead.
