We know that developers will most likely have to cut off a lot of material when they get to the last few stages of developing the game and the same happened to Alien: Isolation as well.
A web designer by the name of Matt Flier managed to dig out a few files from the game that did not make it into the final version. There were a few extra audios and dialogues in there.
While the audio files and dialogue will not change the game in any way, as a fan, it is still nice to clear and read about these files as it gives us an insight as to what the developers’ directions were when they first started working on the game.
The files will not only give us a better idea of what happen to Sevastopol before Ripley arrive but we also got to read about some of the characters in the game. You can check them out here.
