Creative Assembly will use un-released audio from ALIEN for pointers.

"It's frustrating, and a little worrying, because Isolation wants to be the greatest ever Alien homage - lent rocket fuel by the thoroughness with which games developers have trampled on the film's legacy over the past two decades. Its levels, characters and audioscape are the products of an unspeakable degree of research: among other things, Creative Assembly has dug into vast archives of unreleased Alien audio for pointers, and designed all the props using materials that might have been available on set in 1978." - OXM
So hopefully, we will see things in game that we never got to see in ALIEN?
Fingers Crossed!
The poster was good though!
