Cryptos is a computer mainframe in Fallout 76.


Cryptos is a modified RobCo Industries computer mainframe originally built by RobCo for a canceled Defense Intelligence Agency project before being sold to Frederick Rivers. Frederick modified it to optimize martial arts training for his wife, Shannon Rivers, who was preparing to portray the hero Mistress of Mystery in the upcoming Silver Shroud television serial.

After the Great War, the Fredericks founded the Order of Mysteries and he and two members reprogrammed Cryptos to automate functions for the Order. Cryptos can automate registration of Initiates, mentor and mission assignments, and promotions. Cryptos was also interfaced with an automated fabricator to authorize and log fabrication of Order equipment.


  • The Cryptos mainframe is located in the basement of Riverside Manor, located behind a secret door.

Behind the scenesEdit

  • The Greek root word kryptos means "hidden" or "mysterious."
