Years ago, my wife and I were looking for a new game. We saw this at the Babbages.
On the back of the box was an ad that stated "For The First Time We Have Experienced REAL Fear Playing A Computer Game". We though "naaaahhhhh, but it probably means it was good."
The truth is that we both played the game, got the you know what scared out of us. This game gave me the same rush that I got playing Quake the first time some of the monsters would jump out at you.
Be SURE and play the music... They did a masterful job of setting the tone.
If you like horror - this is the game for you
If you like mystery - this is the game for you
GOOD STUFF -- Now bring on the sequel(s)
