Gain All nuclear Codes (any Silo)
Once you obtain a keycard, you will then need to find all 8 Pieces of an encrypted launch code. Each code fragment will have a letter and a number attached to it. If you decided to do the optional portion of searching the archives for more information about code encryption, you will learn these codes and letters do not intend to spell anything, but the letters are coded.
The Surveillance System terminal can help you locate pieces of the codes by narrowing down the last known location of the officer that carries them. You may have also stumbled across pieces during your travels across Appalachia as well, but surveillance system access will speed up this process exponentially.
