Upon starting a new game, you'll be prompted to create your vault. You'll receive a few starting dwellers and a basic set of rooms. Your first priority is to establish a stable supply of Power, Food, and Water. Build a Power Generator, a Diner, and a Water Treatment Plant. Place dwellers with high Strength (S) in Power Generators, high Agility (A) in Diners, and high Perception (P) in Water Treatment Plants to maximize production. Remember to connect rooms with elevators to ensure dwellers can access them. Don't expand too quickly; focus on efficiency and resource balance in the early stages to avoid critical shortages.
