Alien: Romulus - Precurser to the pulse gun

 leading from

Alien: Romulus

 

Alien: Romulus takes place decades before Aliens, and at this time, the Pulse Rifle as people knew it had not been invented. In the extended universe of novels, the Pulse Rifle had been invented a few years before Aliens by a retired USCM Corporal Jonathan LaForce according to the short story Episode 22 in Aliens Bug Hunt written by Larry Correia.

 

So the weapon seen in Alien; Romulus is a precursor,  using pulse technology

 

The story called for a moment when the character Rain is carrying one of these weapons as she comes out of an elavator

 

When they did the shot, they all had the idea in mind "If you walk out of the elevator, it better be an incredible shot."

 

They took a lot of car making sure that she stepped out of the elevator in the best way possible

1. Gamesradar: Cailee Spaeny’s character gets a hero’s entrance in the trailer. Is that a pulse rifle she’s carrying, and is the shot a conscious homage to Ripley stepping out of the cargo elevator on her way to the Queen’s nest in Aliens?

   Fede Alvarez :Yes and yes. It is a Pulse Rifle. You have to think that our movie is decades before Aliens. So the Pulse Rifle, as people know it from Aliens, has not been invented yet. We can go really deep into the canon rabbit hole, but the Pulse Rifle was invented a few years before Aliens by this general. 

   This is a precursor. But it’s technically Pulse technology, what she’s holding. And, yes, of course, the story called for a moment when she was coming out of an elevator. And obviously, you don’t just walk out of an elevator casually in an Alien movie. So when we were about to do it we all knew, "If you walk out of the elevator, it better be an incredible shot." So we took a lot of care, making sure that she stepped out of the elevator in the coolest possible way. (https://www.gamesradar.com/alien-romulus-trailer-breakdown-fede-alvarez-interview/)
