Just another question about this, as I'm no expert on the original: what was to stop the player tooling up and wandering around the ship in a crowd, hunting the alien?
Sorry for digging an old topic, just stumbled upon this remake, I just love the original.
If I remember correctly, character's morale would start to go down if there are 3 or more characters in the same room (simulating the bickering and disagreement between characters), which was why you would have to split a bit things. Also, the time limit would force you to split to go faster.
