You're at your home, just chilling. All of a sudden.. you get an Emergency Alert System notification on your TV, and the typical "BEEEEEP" noises can be heard. Eventually those noises stop, and you stare at the TV as the following text can be seen moving across the screen: "Emergency Notification from the United States Department of Defence, this is NOT A TEST." And then a voice can be heard. The voice would then say..: "This message is being broadcasted at the request of the United States Department of Defence. At 9 AM Eastern Standard Time, multiple long range Intercontinental Ballistic Missiles have been detected to have launched from Russia. They are bound for the mainland United States, and will impact the following areas in 30 minutes: New York, San Francisco, Austin, San Antonio, Dallas, Houston, Miami, Seattle, Washington DC, Oklahoma City, Kansas City, Nashville, Colorado, Los Angeles, Las Vegas, and Orlando. If you are within 300 miles of any of these locations, we strongly advise you to seek your nearest fallout shelter. The effects of these ICBM's are devastating, and they can easily level entire cities. The United States will handle Russia by launching their own ICBM's towards their major cities, and nuclear war will ensue. The president of the United States will be headed for a secure fallout shelter, and he will keep you updated on any new information." The voice then stops, and beeping can be heard again as the TV then goes into this eerie silence. You feel an eerie sense of discomfort, and fear, as you realize that.. it's happening.. nuclear war is happening! You have such little time to find fallout shelter, as the nearest one to your location is about 20 miles from here. You have many choices to survive this nuclear war, and we wish you good luck.

What do you do first?
