Let's Play ICBM - Part 1 - The Premier Loves Surprises.
Let's play ICBM! It aims to be the most accurate simulation of the duty of an Air Force officer assigned to man the missile silos that protect the US from destruction by the nefarious forces of the Soviet Union and their vast missile stockpiles. As the website says, it puts you in the hotseat as USAF First Lieutenant Derek Evans as you defend freedom and keep the world safe for democracy.
The sound during the intro cutscene sequence is mangled because the Smithsonian believes it has the copyright to a 90 year old recording of Morning Will Come by Zez Confrey. If something hasn't fallen out of copyright in 90 years, then what's the point of even having the concept of Public Domain?
