1. The auto leash is annoying and tedious
2. The "evac" half of the game is f**k all tedious and super fetch questy; and doesn't really introduce anything new other than more Aliens, which again does not amp the threat, it simply dilutes it, especially if you have flame equipment.
3. If they were going to show the human element wholesale, and also break the flow into discrete chunks, why not have a section where station personnel actually help you, or move you along? You get a hint of this in security for about 5 seconds and then it's back to business as usual.
4. The Alien is simply noisy as hell. It's funny to hear words like "stalked" and "hunted" just strewn about in reviews like confetti when the alien sounds like someone gave a pack of dobermans metal high heels and then duct taped them together, which is pretty much the direct opposite of the word "stalk". Having the Alien stomp around diminishes the threat over time, and eventually it becomes routine rote: stomp-stomp-stomp, hiding in the thing use the noisy thing, use the fire/explosive thing, move to the next level.
