Yeah apparently its different for everyoneWhen I first saw the alienThing is dangerous!!I was waiting for the transport after it killed axel, I get into the transport and look behind me, I see it drop down from the ceiling just outside the door, I think to myself "meh scripted, bet it'll make some noise then sod off again" but no it walks into the damn transport and kills me! lol.
For me it I spot it at the very end of the hall just as the transport was about to set. It's just its outline in the mist. It see me and starts charging full speed just as the transpo docks. I am really panicking at this moment to find the button to get the train to start going.
