Geek culture references in Doom RPG

Doom RPG contains a number of references to the geek subculture.


 * Entrance contains a computer supposedly running an Operating System called UACNIX.
 * In Sector 2, the player encounters a locked door. A scientist gives the hint that the code is related to the structure of the level.  An examination of the auto-map reveals that the level has been designed to read 1337, which is the code for the door.  This is a leetspeak reference.
 * The game contains a number of computer consoles where map data can be downloaded. The player downloads this data using the Unix SCP program.
 * In Sector 2 you find a computer with a conversation log about a party involving DDR (Dance Dance Revolution).
 * Sector 2 also contains a password 042, which is the Answer to Life, the Universe, and Everything.
 * Sector 4 contains a malfunctioning computer that displays the message "PC LOAD LETTER", a reference to the movie Office Space.
 * In Sector 5, the player must retrieve security codes from an SQL database, learning the syntax of the SQL SELECT command in the process.
 * A scientist found in a maze in Sector 5 complains about computer game clichés, such as mazes and jumping puzzles.
 * Sector 7 has a computer console reporting an error, the cause of which it attributes to "slashdot.org".
 * In the Destroyed Junction there is a scientist in the yellow key area who says "I'm knee-deep in the dead."
 * Kronos, the main villain in Doom RPG, is possibly named after Kronos, the Klingon homeworld in Star Trek.
 * To acces the debug menu, the player has to press the number keys 3666. However, when somebody looks at their respective letters (it's an mobile game after all) they spell the word "DOOM".
