It's been 35 years since Sigourney Weaver and the crew of the Nostromo made sci-fi history, and they tell us how they feel about returning to their iconic roles for Alien: Isolation.

Creative Assembly has released a new video featuring Sigourney Weaver, Tom Skerritt, Veronica Cartwright, Harry Dean Stanton and Yaphet Kotto discussing their return to voice the roles that helped make cinematic history. These actors and actresses return in Alien: Isolation's Nostromo "Crew Expendable" and "Last Survivor" missions, which will be available first as pre-order content for Alien: Isolation, but will eventually be made available for the public (likely for a price).

"Crew Expendable" has Dallas, Parker and Ripley trying to isolate the Xenomorph in the air ducts, while "Last Survivor" recreates the last 15 minutes of the movie after Ripley sets the Nostromo's self destruct sequence. It's amazing to watch Harry Dean Stanton's genuine realization that its been 35 years since the original film debuted.

The Xenomorph will come out of the ventilation shaft and various other areas when Alien: Isolation launches on Oct. 7 for Xbox 360, Xbox One, PC, PlayStation 3 and PlayStation 4.

Alien: Isolation is scary as hell, but is it creepier than 5x5's Creepiest Moments of Resident Evil?
