Spoiler alert for a certain game that does not exist.
And I'd also like to say that a certain game does NOT involve a scene where which a missile is launched at something that is NOT a Combine superportal that was NOT being generated. It also does NOT have anything to do with giant slugs with little tongues that are NOT very long. The slugs also do NOT levitate people, turn them around and kill major characters. They're also not called Advisors. The game does not end with a nasty cliffhanger related to a ship that is NOT called the Borealis which also had nothing to do with Aperture Science.
