• Actor Allusion: One chapter has Heimdall taking the place of Janet Frasier, both of whom have the same (voice) actress.
    • Elizibeth Weir is startled to find that Narim (a Tollan) and her fiance look nearly identical (again, same actor).
    • Cameron Mitchell makes several comments involving surfing in his first "on-screen" dogfight with an alien craft. Ben Browder, who played Cameron Mitchell, is an avid surfer.
  • Crazy Awesome: X-COM in general.
  • Creator's Pet: X-COM can come off as this. They're smarter, more skilled, and better equipped than the SGC. Justified, subverted, and played with:
    • Justified in that X-COM really does recruit all the top people in the world, both soldiers and scientists. If anyone in the SGC was remotely good enough to even get looked at by them, they'd probably already be serving in X-COM.
    • Subverted in that X-COM really is a blunt instrument, less suited to the missions the SGC undertakes that don't involve shooting everything that moves, then shooting it again just to make sure.
    • Played with in that, while X-COM comes up with brilliant ideas (frequently leading Carter to remark "Why didn't I think of that?") the SGC still did most of the legwork, and X-COM is just riding their coattails.
  • Hilarious in Hindsight: Andianov's objection to Harlan making an android duplicate of her falls flat some time in the future.
    • Many of the Call-Forward jokes are deliberate attempts at this, such as insinuating that Rodney McKay didn't really have a place anywhere in the Milky Way Galaxy.
    • Several characters espouse that the Kelownan version of X-COM, with a 1940's tech base, would be interesting to see. Though it might be twenty years after that, the X-COM game "The Bureau" was in fact about a very early, primitive X-COM (in the 1960's).
  • Magnificent Bastard: Ba'al, even more so than in the original work.
  • Name's the Same: Averted. In the X-COM series, the type-1 alien fighter is called the Wraith. To avoid confusion with the space vampires from Stargate Atlantis, the author decided to call them "Foo Fighters," after what pilots called UFO's during World War II.
    • There is a Jaffa Pilot named Ronan who appears briefly in chapter 41, who has a homophonous name to the Satedan Runner from Stargate Atlantis. However, given that the Jaffa never appears again, it's safe to say that the Jaffa Ronan will probably not have any meaningful impact on the story.
