Judging by the reviews, it certainly can approach that level; you just have to do what the game says - turn the lights out, wear headphones and adjust the gamma on your monitor so it's as immersive as possible.
It certainly set MY heart pounding, and more than once I had to pause the game, pull off the 'phones and look around the room.
One time I almost stopped and yelled "Who's there?!"...
The guy in the video having his friends on while playing means he at least has an audience
for his outbursts, which could explain a lot.
I have known many women who would not jump and squeal at horror flicks unless they had a boyfriend there to catch them.
