The Bunker escape room

A Cold War era retaliatory missile defense program has suddenly activated and you are in the only facility capable of stopping it. The date is August 1, 2009, and you are the first to arrive at your new military post inside the Ochs-Bragg Missile Complex (OB-16.12). Shortly after your arrival, a sudden event inexplicably triggers a total lockdown of all doors and controls and immediately initiates what appears to be an automated missile launch countdown. Has the computer detected a real nuclear threat, or is the launch system malfunctioning?
