I just finished the game, I will be starting the Nostromo DLC next. For anyone still debating on buying Isolation, if you are an Alien fan what the hell are you waiting for? This game could not do a better job of being a sequel to the movie no matter how much harder they tried. It's a tribute to everything that was Alien and none of the sequels that followed it.
I'd go as far as to say this is the second best piece of Alien media only to the original movie itself, even Aliens doesn't do Alien a sequel as proper as this game does IMO.
The game has some amazing lighting and a beautiful true-to-form art design. There are so many moments where i just stopped and said to myself "This is the Alien game I've always wanted, the one fans have always asked for."
Having said all those wonderful things i'd like to point out two flaws.
Number one is the performance issues. I played the Xbox One version which of course has the short end of the stick when it comes to current-gen offerings but I've heard (As you all have from DF) the problems persist on the other platforms as well. Frames will drop often in game mostly when stuff is getting intense but sometimes it will just drop for what seems like no reason.
Number two is just how much the game drags towards the end. Don't get me wrong, every moment was enjoyable and more content for your buck is always great but i really feel like they could have condensed the game a bit more and changed the flow a bit. I thought i was at the end of the game several different times but it always seemed to keep going where you never thought it would.
All in all if i was going to let those two issues slide i'd give it a 9/10 but being critical and including those gripes it's definitely a solid 8 anyway you look at it. It honestly seems criminal IGN gave this game a 5.9. I can't see that score in any capacity. By the way, if you get scared (or jump a lot) this game isn't near as bad as stuff like Amnesia or Outlast...i jump really easily and between the amazing sound effects and my radar, more times than not i was prepared for the alien's presence.
Basically, if you're considering this game BUY IT!
EDIT: Just beat the entire Nostromo DLC in 25 mins. Slightly nostalgic but ultimately very short and uninspired. I just realized the other half of Nostromo DLC is only if you pre-ordered the game at Gamestop...that really sucks.

Consumers who pre-order at GameStop will exclusively also receive "Last Survivor" in which players pick up the story as Ripley tries to escape on the Narcissus. On hearing the screams of Lambert and Parker, players must navigate their way back down through the Nostromo in order to activate the self-destruct sequence, before retracing their steps back to the Narcissus shuttle and their escape.
