I....WTF..Shit there is Pinhead from Hellraiser! everyone walk to the wall and keep looking to the stones he will get bored to death and leave us alone

You miss the point, as Daniel looks at the monster, his fear increases, as his fear increases he breaks out in a cold sweat, the monster can smell that sweat and hunt him down.
So don't look and calm down and the monster walks off.

If you want a game where you can look at and kill more up-to-date zombies, check out Left for Dead - I just played that game and its a great shooter. But, unfortunately, not scary.
