Nice videos and it looks promising. I guess I can buy that the Nostromo might have ejected a flight recorder pre-detonation, as standard protocol or something. This game better explain why the company didn't go back to LV-426 after they found it, though.
I'm honestly expecting a level of linearity similar to the Bioshock series, which had a decent amount of free-roaming and backtracking, but when it came to characters was mostly instance and room-based, scripted stuff.
That will be fine so long as the Alien has a degree of randomness to its' behavior, and the writing is solid.
It's like a big secret that if they put some effort into developing real characters with decent writing, their demise adds to the horror immensely.
