2. Ridley Scott implies that the world of Blade Runner and Alien are connected "in a way".
3. As part of the 20th Anniversary Edition "Alien" DVD in 1999, a DVD extra titled "Nostromo Dossier" shows extended profiles for the crew that were seen in the background during Aliens. Dallas is shown to have once worked for the Tyrell Corporation from Blade Runner. However, the Tyrell Corporation would have been defunct by the time Dallas was born, becoming part of the Wallace Corporation. It is possible that it resurfaced after Blade Runner 2049, like Weyland-Yutani did after the Walmart buyout.

4. Ridley Scott remarks on the director's commentary for Blade Runner that they could be connected. "There's almost like a connective tissue between all the stuff I went through on 'Alien' into the environment of the Nostromo and people living within close proximity to people who still have Earth-bound connections and here we have people on Earth, so almost this world could easily be the city that supports the crew that go out in Alien. So, in other words, when the crew of Alien come back in, they might go into this place and go into a bar off the street near where Deckard lives. That's how I thought about it."
5. In Soldier, Todd's weapons training record lists the "USMC Smartgun" and "M41A pulse rifle" from Alien, although it also references things that it isn't in-continuity with as well, like Star Trek and Star Wars.
6. Soldier establishes that the United States Colonial Marines Corps exist and fought in various battles including the Tanhauser Gate conflict mentioned in the original Blade Runner. However, they did not exist in the Alien Universe until 2101.
7. There was an idea to have the Weyland and Tyrell corporations be merged in Prometheus, and have a bodyguard with a name referencing Roy Batty. "There's one idea that I'm very sad that we didn't do. Ridley, one day, came in and said, "You know, I'm thinking what if it's the Weyland-Tyrell Corporation? Is that cool? Maybe the bodyguards, you know, that come out with Weyland, maybe one of them says Batty on his uniform. And we're like "Awesome! Do it, do it!"

8. In Peter Weyland's 2023 TED Talk, he remarks that it is illegal to create robots indistinguishable from humans. In Blade Runner, replicants were declared illegal after a NEXUS 6 mutiny in an off-world colony. Technically replicants aren't robots, but the point stands.
9. A blu-ray extra for Prometheus suggested that Tyrell was Weyland's mentor.

However, the writer of this text downplayed the connection, indicating that it was intended as an easter egg, with the Blade Runner connection technically not being officially established.
10. In Aliens: What If...?, Arcadia 234 from Soldier appears, despite its apparent destruction 143 years prior. The android throughout the story, who was recovered from said planet, is referred to as a replicant on several occasions. He does have white blood however, suggesting he is not literally a replicant. The term replicant is still a known in-universe term.
