Does modding ruin the fear of the game?

Here is what you do:

Step One: Have your story lead up to the idea of there being a monster.

Step Two: Have the right music to make the character expect the monster.

Step Three: Have noises in the background sound like there is a monster.

Step Four: Don't use a single monster. Just make sure everything looks good enoug, the ambiance plays at all the right moments, and include a lot of dark corners. No one will see it coming.

I made a map just to test ambiance, but I can't get it to load, so I am sure it sucks.
