The world has changed a lot and global social climate is really tough now. The countries are waiting for a massive nuclear war and smart people like you get prepared for that. Build yourself a shelter and do your best to ensure tools and production that will help you work, get food, and craft. Be smart and have a plan of your actions – follow it and change things according to the current events. Also, the government behaves strangely and hunts people around the cities, so keep yourself away from the secret police that wants to control your will.
