I adore this game, believe it's the best Alien game to date, especially modded, but besides Stompy having their footsteps be too loud, I also find another thing unfortunate. I love the fear and mood it creates, but neither in the movies, nor realistically would anyone be able to hide from the Aliens. You can't do that from most predators cause of their sense of smell, so I'm certain you wouldn't be able to from an Alien, not for long, that's why you have to be on the move constantly. I always preferred the interpretation "you can run, but you can't hide".
After seeing this video, I especially got reminded of that. Spoilers, almost impossible to escape:
