One of the Bbest parts of that game: while your trying to detach the ship right near the end.
I remember being completely on edge the other times you get get forced out onto the ship's hull. The Aliens don't seem to mind the whole space thing, and trapped in that cumbersome suit, I was just waiting for something to happen.
It never does.
Then, right at the end, you escape outside from the control room after being hounded by 3 xenos all at once. After nothing happened the last few times, it felt like a breath of fresh air. It felt safe.
But as you detach the ship, if you look real far off into the distance, you can see the three aliens slowly trying to creep their way toward you without slipping off into the vacuum.
The game doesn't prompt this in any way. They're pretty easy to miss before they get right up in your business.
But it really creeped me out (and made me almost shout at the screen for Ellen to hurry the f*** up).
A nice callback to the films with things getting worse right as you think they're done I suppose. And Isolation does it TWICE.
