Metacarpal Gloves: Designed to protect your hands from mining accidents, these babies are padded, reinforced and badass.
Pick Axe: A must have. It can help you clear rubble to a possible escape, be used for climbing to safety and can fight off cave zombies. Those guys are no joke.
Fire Blanket: You can put out a fire with it, use it to protect your skin from flames, or it can keep you warm when temperatures drop to freezing.
