You, a random individual, living in a random city, wake up on a random day and notice the electricity has stopped working. Rubbing your sleepy eyes, you walk down the stairs of your apartment block to check whether or not your neighbours are having the same problem, but nobody appears to be home. Hardly awake, you go back into your apartment to brush your teeth and take a quick shower, trying to navigate using the morning sun and a flashlight. Unfortunately, no water flows out of the tap either. Surprised and certainly annoyed, you try figuring out what's wrong and, using your cell phone, try calling a friend of yours, but the network connection appears to be down as well. With no other option but to go outside, you quickly realize the streets are completely empty and no clear sign of any human being is around. All you sense... is utter silence.
