Those screenshot comparisons above are amazing! I love the Alien films, and to see the attention to detail that CA put into this game is very impressive.
Part of me really wants to get this game, but I'm such a wimp when it comes to horror games. I couldn't play Outlast for more than an hour with headphones on (I eventually did beat it, but I played with the volume low so I didn't have a heart attack). I feel like the sound is so essential to this game though, so I might have to suck it up and play with headphones on at night.
Reading the impressions in this thread has really tempted me into getting this. I saw the Giant Bomb Quick Look, and while some aspects seemed frustrating, it's still very appealing to me. I have been playing so many racing games lately that I feel like I need a change of pace.
