i love dead space so much kc
it's the first game to make my physically sick due to disorientation
it was beautiful

anyway you should try silent hill 2 one day

edit: it does this cool procedural sound generation where if something is right behind you it won't flourish the intense fight music until you turn around to see it. it was probably the audio shock you experienced, i felt it a few times during the game. i remember the beginning being particularly frightening because they just throw the monsters at you and you cannot fight back and have to run.
