I just caught a local TV station game review show, that reviewed this in a recent episode.
They gave it
8 / 10.
In short, they mentioned that, apart from the obvious attention to detail in capturing the aesthetic of the original film, it definitely delivers in the fright dept. However, certain things let the game down;
like having to reload from the beginning if you die, due to no auto save points, some of the A.I being a little unresponsive at times, & one or two other minor things like an unnecessarily high amount of locked doors to mess with, & a lot of walking around before you actually encounter any menace of any kind - be it crew, androids, etc..
As far as I'm concerned though - from everything I've seen & read so far, it's a definite buy for me.
