Trivia

 * The arrivals board at the start lists City 17 as a destination, which is the setting of both episodes of Half Life 2.
 * In the vending machines seen early on in the story, the list of available drinks includes Citranium Soda. This is a reference to a slightly earlier Portal mod, Aperture Tag, which includes Citranium as a 'sponsorship' gag.
