OHF- Cerberus Code

Cerberus is being used by the "Koreans for United Freedom".

Cerberus was a highly-classified U.S. military protocol and a fail-safe device which, when activated via three different access codes being entered, would help unleash a nationwide nuclear meltdown in the country. It was also used to prevent any ICBM missiles from reaching its target in case any of them were involuntarily launched. The President, the Secretary of Defense and the Chairman of the Joint Chiefs of Staff were given one code each that would help activating this protocol if ever prompted to. On the other hand, Cerberus was designed as a self-contained, total-isolation system once the codes were entered and the only way to disable the protocol is physically the computer located inside the Presidential Emergency Operations Center.

Kang Yeonsak gave Lim the task of unlocking and inserting every code that they found from the appropriate people every hour.


Cerberus was the Greek and Roman mythology name of a multi-headed (usually three-headed) dog, or "hellhound" which guards the entrance of Hades, to prevent those who entered from ever escaping.
