I got my UK copy early yesterday from GAME uk and the 5.1 sound is messed up. Every 10 seconds or so the sound mutes for a second and then comes back and this process repeates almost constantly and is distracting.
A quick search of Google shows that many owners of the game are experiencing this problem and Sgea's official advice is to use component cables and stereo sound only! Thanks Sega, that really spoils a game which relies on 5.1 asmospherics. Apparently Sgea and Monolith are looking into a patch but they're not coming across like it's a great priority for them.

downloaded the demo and played it at midnight with my mates with all the lights turned off and the brightness on the screen really low

really scary! oh my god it is scary, my mate almost refused to play anymore because he was scared, especially of the ghostly wheelchair

brilliant to play with mates, although would get boring on your own in the day

I brought this game because every1 was like yeayeayea, Lots of blood, good graphics!!! When i got it n started playin i was like wdf? graphics are OK game play is OK, ONLINE IS 0/10 AND THE GORE IS NOTHIN 2 GET EXICTED ABOUT!! If u want 2 waste your money i suggest u buy this game! Very dissapointing.

Very few film or game makers understand the above phrase and sadly think people are scared by huge monsters or severed limbs and bucket loads of blood and guts. So when a horror game or film comes along that makes use of sound, lighting and ambience in the right way it's massively refreshing. This game does what you want any horror game to (although sadly few do...) it unnerves you and has you feeling reluctant to move forward further into the game world. And the best part is it does it all without in your face monsters and ridiculous amounts of gore, in fact the game's biggest strength is that it doesn't show the player too much, it doesn't offer an explanation for everything it leaves much to the imagination and is all the better for it. Another positive is the way the game and its story positions itself in a grey area between the realistic and the supernatural causing the player to question whether or not theres actually anything unexplainable going on or not.
Then theres gameplay itself, the game focuses massively on close-quarters-combat and the variety and peculiarity of the melee weapons available makes more for some entertaining scraps.
Theres also the CSI style forensics aspect which is a nice touch and breaks up the combat moments in the game well.
Overall a truly brilliant and disturbing horror FPS.

I have just finished this game and what an experience!!! I have not enjoyed a game like this since Resident Evil 4. It has fantastic graphics and gameplay and is unnerving to say the least. Very threatening and violent but very playable. It is not for the squeamish but has to be played in the dark! Brilliant game making. 10/10.
