I've just quit a 60min Bioshock session since there is only so much my heart can take. I'm at the begining of the game and just got the shotgun. The part where you pick up the gun, the lights go out with the spotlight focussed on you with the zombies in the dark circling you is the most scary thing I've seen in a game. The even drag their weapons across the floor for added scare factor 
The moment the lights went off and I heard them coming, I paused the game and litteraly swore at the screen for making me go through this
I don't even wanna think what else lies ahead. Some people say Dead Space is even more scary.
*stares wearily at the unopened Dead Space game next to the PC*
