As a Moments subpage, all spoilers are unmarked as per policy. You Have Been Warned.
- One early, but mercifully Dummied Out feature was to sic a Titan on you if you hung around an investigation scene too long. Considering its firepower (a massive beam able to obliterate cover), it could make everyone haul ass at lightspeed.
- In the first trailer, one of the slithering black blobs killed an XCOM agent by forcing itself down the agent's throat. Luckily, in the game they're relegated to the role of Goddamned Bats.
- The Sleepwalker Virus. It makes people repeat the same short moment from just before the infection, and even the most strong-willed ones can resist it only for a limited time. And I Must Scream.
- Among the first victims you come across is a barber, who keeps running a razor along the cheek of a corpse sitting in the barber's chair. Naturally, the cheek is very bloody by this point.
- The live action trailers
show the Bureau going to frightening extremes to do their work and keep the truth hidden. Carter readily engages in Jack Bauer Interrogation Technique with a captured Outsider. They "contain" an Outsider attack in a small town with the help of flamethrower troops, round up and incinerate all Sleepwalkers and finally Un-person the entire town. Cole's resignation letter indicates that resigned agents may be committed to an insane asylum for the rest of their lives if that is deemed necessary for plausible deniability. - The Infiltrator's fate and what Carter decides to do about it. After weeks of learning how it feels to live in a free country, a spy-turned-defector is promptly restrained and reconnected to Mosaic just so they can pump him for intel, by re-installing his enslavement chip the same way they removed it surgically. This is what cements Carter's Face–Heel Turn; if the country you spent your whole life to defending the freedom of decides they love the mind-control technology of the genocidal aliens and want it for themselves, especially the all-powerful psychic poltergeist who has personally been controlling Carter like a puppet, why should you care about protecting them any more? Why not simply kill them all?
