Trivia

 * The systems can be seen in the level foundation. You can see "Abandon in Place " written on them, hinting that it was a failed project.
 * The acronym TARDS is an possible joke by Bungie, given that it sounds like an abbreviation of "retards" or the "TARDIS" from Doctor Who.
 * TARDS's facility in Chicago may be a reference to the location of U.S. Robotics in the 2004 film I, Robot.
