When connected to any other known data server, the DERRIESE system can be accessed by typing rlogin derriese within the in-game computer console and then entering a valid username and password.
A list of usernames has been found by opening the game files although no respective passwords are available. They are as follows:
- Within a file on the home directory, encoded with a standard CIA cypher, a man called Peter, also mentioned as the CIA infiltrator in Group 935 that had to be extracted by U.S.M.C. Recon member Tank Dempsey.
- There are several files found in Dr. Vannevar Bush's home directory, name-patterned as Servant####.TXT. These are data files stored by Dr. Maxis, that Dr. Vannevar Bush and Dr. R. Oppenheimer retrieved from the Verrückt archives.
- There are 2 accounts named "edward" and "erichtofen", despite being the same person.
