I'm pretty sure that there will be alot of moments were you can feel your heart bouncing like hell.
"You are in full concentration in a quiet and scary place. You're heart is beating like hell and you get an incredible adrenaline rush. Then all of a sudden, a bloodsucker pops up out of nowhere, and you get so damn scared that you shoot all over the place."
I'm sure most of the ppl here experienced that before. In SP and MP
Hehe, even scarier is after you reload (having been killed by the bloodsucker). You sit down quiety as you were before - this time concentrating and waiting for the bloodsucker... but it doesn't come. After ten minutes you relax, deciding he must've gone some other way this time round, only to be ambushed by him as you turn around
the tension and mood all depend on the game generally. along with music, which generally sets a scary mood. if you watch a horror movie without music you notice that it isnt as scary, or constantly scary. this also just depends on the type of player, some jittery player, a big bad ass player...and so on. there is no correct answer, just the personality of the player. now you could debate what YOU think is more scary, but thats just your opinion.
it's dangerous to be right when the goverment is wrong
