The bunker was five stories underground. On the top floor, the first floor, was the entrance, post, information, and defense. On the ground floor, there was a hospital with things found in city hospitals. You could buy them for food if needed, and they treated you for free. On the -1 floor, there was a garden with fruits and vegetables. Maybe they raised meat there, but you only heard the sounds they made. On the -2 floor, there were tasks for which you received food. On the -3 floor, there was a cafeteria where you could cook food or someone would cook for you. On the -4 floor, there were rooms for singles up to five people.
