To be fair, he hasn't even seen the film version of the movie. I think that it was conceived as its own thing but people on the production had a different idea.

Also, this isn't relevant or even part of Blade Runner/Soldier canon, but Aliens: What If...? #2 featured Arcadia 234. In the Alien Universe, it hasn't been blown up and still exists in 2179. I just think it's a cool easter egg/nod.

They also keep referring to the android recovered from Arcadia 234 as a replicant. He isn't literally a replicant, like the Tyrell/Wallace bioengineered kind. He has white blood. Still, cool that they referenced both Soldier and Blade Runner in an Alien comic book.

Paul W.S. Anderson confirmed that it's connected on Soldier's commentary. Considering that David Peoples called it a spin-off originally but then said that it was actually not that and came as a response from Terminator, I think this:

1. Soldier was written as an original idea, separate from Blade Runner to begin with. Peoples never saw the finished film though and he's talking about when he originally wrote up the story for Soldier in 1984, literally 14 years before the film actually came out.

No, I never had any thoughts about that... I wrote Soldier in 1984. Very quickly on my own. I wrote it because I saw the first Terminator in the theater, stunned. And it was such a wonderful movie. I'd always wanted to write a movie in which there was a tough guy who would be seemingly unsympathetic in the lead, and I felt that The Terminator was almost there. Later in the sequel, it was determined he was the hero, but at the time, he was sort of a villain. But the fact is, he was so great. I went off, and I decided to write about this soldier."

2. Soldier became a spin-off down the line for both David Peoples and the director. Quoting Anderson:

"Now, on Kurt's shoulder there is the Tanhauser Gate. That's one of the battles that he fought in, which people might recognise from Blade Runner as well, Rutger Hauer talks about C-beams glittering in the darkness off the Tanhauser Gate, and David Peoples also did the adaptation of Blade Runner. There's a lot of references to Blade Runner in this film. I always saw the two movies, Soldier and Blade Runner, although they're very, very different, as existing in the same universe, so that if Kurt ever went to Earth, he'd encounter Harrison Ford down there."

"So, yeah. Blade Runner was a constant influence to us during the making of this film. And also thematically, Blade Runner is very much about the machine that becomes as human as it possibly can be, Rutger Hauer's character, whereas this movie is about the man who becomes as machine-like as the military can make him. So in a way, both Kurt and Rutger are looking for their humanity."

3. Both films are owned by Warner Brothers.

4. The film contained the implication of replicant soldiers replacing Todd.

5. A police spinner from Blade Runner appears.

6. The wars from Blade Runner are shown on computer screens, tattooed on Todd's arm and the Tanhauser Gate conflict is mentioned in dialogue.

7. 2036: Nexus Dawn, purposefully or not, sets up the events of Soldier.

8. The references to Blade Runner and Soldier in Aliens: What If...? were confirmed to be because the writers considered it the same universe as Alien during a podcast with AVP Galaxy. (Less relevant but still, it places Blade Runner and Soldier together)

So obviously I don't agree that Soldier isn't connected. I think Anderson's comments are quite explicit. The word of the director who made the movie is more important than the word of a screenwriter who previously said it's a spin-off saying that he wasn't influenced by Blade Runner when he wrote the movie (that he never saw) 14 years before it released.

My main thing is that nothing in any Blade Runner material explicitly references Soldier in any way. And although Anderson may have intended it to be set in the Blade Runner universe, the production companies may or may not have seen it that way. It certainly wasn't marketed as being a spinoff/sidequel.

While the Blade Runner films and Soldier are distributed by Warner Bros, the Blade Runner IP itself was owned by the Blade Runner Partnership from 1982 to 2012, and they had no involvement in Soldier whatsoever and they would have had to sign off on it being officially part of that universe. Alcon Entertainment purchased the Blade Runner IP in 2012, and that did not include Soldier.

So it doesn't appear to be officially part of BR, but at the same time, nobody with any real say is going out of their way to say it's not at all connected. And with that said, I don't personally have any issue with it remaining on the wiki.
