There isn’t really much dots to connect in the Alien: Isolation game. The story is pretty clear throughout the game but it looks like the developers did have some extra materials that they decided not to include in the game.
Web developer Matt Flier was looking through the files of Alien: Isolation and found some extra audio and dialogues that were supposed to be in the game but was later cut out. The content of the files will not affect the ending or the story of the game but it does give us some additional detail about the game.
We got to learn more about Sevastopol and the things that happened at the station before Ripley landed there. We also got to learn more about some of the characters in the game as well. If you would like to read and hear them for yourself, click here.
