Alright, put a bunch of hours into it now, final verdict: fuck IGN, gamespot, or anyone else who gives this less than an 8/10. This is legitimately the greatest Alien game that's ever been made, and easily one of the top 5 survival horror games I've ever played.
It has some rough edges here and there, to be sure; namely in the frustration department because of the manual save system. I still consider that an excellent design decision, but sometimes there's just a little bit too much distance between manual saves and I quickly become neurotic in the search for another before I'm horribly mauled. Maybe it's because I'm playing on "hard" and the Alien has seemed to have caught on to my "hiding in lockers" trick and has now started checking them pretty regularly, to my unabated horror.
It has so much emergent, random gameplay, both with the alien, the survivors, and interactions between the two. I was exploring a small cluster of rooms connected to a hallway, and after seeing several blips approaching me, I ducked into one of the rooms and got into a locker. I then witnessed 2 people run by, and then right in front of the door (in view by me) some guy gets tackled from behind by the alien, and the other guy gets wrecked seconds later. This wasn't a scripted event, I could've easily been in another room entirely and never saw that, so I have to expect it was just one of the many "emergent survivor deaths" that I've already witnessed several of.
I torrented it until now but I just dropped the 50 clams on Steam, because honestly I haven't been this entertained by a game in a long while, and I'm kinda worried that creating such a niche product for alien and survival horror/stealth fans wont work out for them, monetarily speaking, and it certainly deserves at least 10x the profits the travesty that was Aliens: Colonial Marines saw.
To anyone on the fence, I recommend watching a few streams. I think Angry Joe did one for a few hours on Twitch, and I'm sure there's a bunch of others. Guy in >>50060's video also did a good one. He has a system set up where anyone who donates to his stream triggers a loud scream into his headphones, so it's fun to watch him nearly have a heart attack during the tenser parts of the game.
