Scariest Video game moment

This is not the scariest game you play, it is the event or moment in a game that keeps getting under your skin or scary the sh*t out of you.
 
I would have to go with the underground levels of STALKER with all of the lighting, sound effects, and the contain reminder that weird creature is still lurking around. 

Resident Evil.  PS1.  Those evil bastard dogs jumping out of the windows in the first long hallway you go down.  I jumped out of my chair like a little bitch :)

System Shock 2 
 
using a vending machine, activating a door, etc. only to have a ghost pop up in front of you. I lost plenty of bullets shooting at those darn things >___>

In Resident Evil 4, the enemies that you have to use thermal vision to see where to shoot them. It was one of our first encounters with the foe. We shot him and he fell to the ground and we just laughed as it wiggled around on the ground as it tried to crawl at us. We didn't know they could leap and attach themselves to your neck. When it did that, we both jumped, and never let one of those things get that close again. 
 
Also, Fatal Frame II is full of these moments. So many well-crafted scares in that game. Also, there were so many points when figures or faces would appear in the environment for a couple of seconds and just fade away. I would say something like "Oh wow, I could of sworn there was a face in that wall." And then my friend would say the same thing. Then I set the controller down for a couple of minutes, refusing to move forward as we checked the recording to see if there was actually a face. 
 
There was :(

Resident Evil 1 on the PS1.  Basement kitchen.  Screechy music.  Tight camera.  Tiny room.  Nasty music.  This one really sticks with me.

It may just be because I recently replayed Pikmin 2, but Submerged Castle kinda freaks me out even today, must be because of the music and that other "thing"

Getting chased by Pyramid Head in the hospital in SH2, so unexpected.

Don't like  scary games so I haven't played alot of them, but my scariest moment was from one of the forensic scenes in Condemned when the victim turned out to be actually alive.

The third level of Killer7. You're in a town that's just over-run with Heaven Smiles and it's just ridiculous. That game freaks me out a lot, but at that point, I was really losing it.

The night vision level in Star Wars: Republic Commando. The most intense sequence I've ever played.

Seeing the red ring of death stare deep into your soul.

Silent Hill 2.  
      

" Condemned criminal origins-the locker scene Fatal Frame-random ghost encounters Fatal Frame II-The Twins randomly appearing in the house with no notice what so ever.Fatal Frame III-The crawling woman scene,long haired woman appering in front of the camera Silent Hill 4- Finding the dude inside the wall. Haunting Ground-Being chased by the invisible dude. System shock 2-shodan reveal Resident evil 4-Regenerator battles Just a few I can remember. "

Not the scariest moment I can think of, but the first thing that came to mind;
 
Condemned 2, that bit with the mannequins that suddenly appear when you turn around.

" @gabha: Did you see it coming? I totally knew something was going to happen, but it still scared me anyway^^ Also, that last level in Condemned, when you're in that house with Serial Killer X, is some seriously messed up stuff. "

First time you meet a Bloodsucker in S.T.A.L.K.E.R.; when you first find one of those ninja-enemy things in FEAR that sit in a top corner of a room until you look up; or the whole of the Penumbra series.

A lot of Condemned 2 since that games great with its jump scares and creepy atmosphere.

Bioshock dentist.

I've played quote-unquote SCARY games like Silent Hill & Resident Evil.
 
But for some reason nothing has ever freaked me out like the Ravenholm level from HL2.

I think it was in the original F.E.A.R.  I remember how I saw the hallway filling up with fire coming my way.  I stood there for a few seconds and then booked it towards the window, scared shitless as I did.  Here was my exact though process: "stupid game designers, that's obviously an illusion and it's just going to disappear in a second.  Wait, isn't that that psycho little girl murderer on top of the fire?  Wait a sec...OH SHIT OH SHIT OH SHIT OH SHIT OH SHIT!"

Getting chased by that Bear in Condemned 2 was a pretty intense scene.

I never played the demo, which apparently had it too, but the infamous ladder bit in F.E.A.R. got me this close to soiling myself.

Regenerators in RE 4 

Amnesia: Dark Descent. That invisible water creature. Anyone who's played the game will know exactly what I mean.

Anything fro Fatal Frame

Probably in the original condemned, the manequins in the dept store moving right next to you when you look away.

Particularly the poisonous black headcrabs that drop you to 1 health in a single hit. That level took me about 3x as long as it should have just because I inched my way around every corner figuring one of those things would jump out at me.

Possibly the dog kennel part in Penumbra: Black Plague. Or the second Hunter part in Dead Space.

Resident Evil 1: Dogs jumping through window. That's a classic scare and usually the first thing I think of whenever this topic comes up.
Resident Evil 2: Licker jumping through interrogation room window.
Resident Evil 3: Almost any part where Nemesis chases you. 
REmake: Every Crimson Head encounter, and pretty much that whole game
Fatal Frame1: Almost all of the random ghosts
Silent Hill 1: Locker in school
Silent Hill: Homecoming: The Siam that bursts through the prison gate with absolutely no warning, and the Siam that comes barreling behind you at the end of the sewer area.
Condemned 2: The mannequins that follow you in the abandoned apartment, and of course, the bear chasing you through the cabin.
Metro 2033: Being chased by the librarians, and trying to avoid waking the librarians up a little later.

Anytime in Penumbra..

The Winter Lodge Demon Door in Fable 2. Not the scariest moment ever, but it comes out of nowhere.

resident evil 2 for n64. i jumped a couple of times not expecting zombies to be sitting at the windows grabbing me. it is one of the things that scared me. sometimes i would play it at night time so i would start hearing weird things. night time make games even scarier.

Probably because it's still fresh, but the water level in Amnesia is the worst. Or the Storage. Hell, the whole game is bad. But, yeah, the water level. That's not human. 
 
When I was younger, I didn't really like the headcrabs in Half-Life. Whenever they started to jump me I would freak out completely.

System Shock: SHODAN's reveal.

I've never really seen anything quite like that.

The moment I started playing Two Worlds. 

Personal favorites of mine were being followed by the emotion-less killing machine B.O.W in Residen Evil 2's 'B Game'. That thing was far scarier than the Nemesis in RE3 because of his silent lumbering stalk, and his ability to smash through walls and chase you in rooms that were previously considered 'safe'.
 
Also, most of 'The Suffering' was pretty fucked up. Not just jump scares, but a really un-nerving feeling made from excelling creature design and some of the best audio work I've ever heard in a video game.
 
Also an Xbox indie game called 'Soul' is great for scaring kids and relatives, It's basically a game built around Ebaums prank maze but it's actually pretty good and I'm pretty sure Team Meat has played it too as some of the creatures in it look very similar to those in Super Meat Boy. Oh and only costs about 70 pence.

Leliana singing in Dragon Age.

Minecraft, Godam creepers! 
 That is the most recent one,  I don't think A game has actually scared me for a VERY long time.

Back in the day, being chased by the Dahaka was pretty damn creepy/intense.

Dogs jumping through the Windows in RE1 (PSone) is probably the best jump scare I have seen, it is so simple, yet so effective. In the remake it didn't felt half as good as in the original. 
 
Another classic moment: The dark troppers in Dark Forces, I always found those rather frightening. A big strong enemy that you could here coming from quite a bit away, but not really avoid fighting, kind of like the Big Daddies in Bioshock I guess, except those lost their scare due to the Vita Chambers pretty quickly, in Dark Forces on the other side I played without quicksaving.
