You're out on a supply run once again, needing food and drink to survive, as you come across a massive supermarket, abandoned due to the zombie outbreak, as you head inside, with your gun holstered, cautiously walking around, searching every shelf, and refrigerator, luckily, the food and drinks haven't expired yet, since it hasn't been that long since they closed down the supermarket, you're searching through every fridge, grabbing everything you see, making sure not to miss anything, when all of a sudden, you hear something, or someone, moving around on the second floor, you decide to check it out, as you slowly make your way upstairs. "Who goes there? Come on out! Don't make me find you! I won't hesitate to shoot!" You yell, aiming your gun at wherever the noise came from, not taking any chances, even if it's a survivor, since you know that not everyone is friendly, and it's survival of the fittest.
