Extracted directly from the game files using the Audio Extractor tool.
This climax piece was separated intro three files that I put back together to form a much more cohesive track. As the final bits from the last minute and ten seconds aren't heard that well in-game, I did my best to form something that sounded good, or at least, good enough.
The first four minutes are also used in the base game after Amanda discovers that Ricardo got facehugged, and I guess there's no need to say that this is a remix of 'Escape from Habitation Decks', or viceversa; no idea which one got composed first.
Happy ten years, Alien: Isolation! One of the greatest survival-horror games ever made.
