When I realized I had to play two-man-down in a 4v4 match at MLG Orlando. R6:Vegas.

Hearing click, click when you pull the trigger.

Friday the 13th for NES, walking into a cabin and seeing Jason...
Jaws for the NES, having the fin pop outta the water and follow the boat.
About every third minute while playing FEAR or Doom3...

Realizing that I'm going to have to totally replay the last two hours because the game glitched and froze.

The first time I hit The Library in Halo. Zombies - bouncy, jumpy, flaily, zombies. Ew.

Actually, I'm more prone to GodDAMMIT! than "oh...no."

Huh?

American McGee's alice. First time I played it, it was on nightmare mode. Finally got to the final boss, cat dies, killed the bitch, horrible mind destroying speech followed by Kraid-like tentacle monster with a giant mouth in the center.

Realizing that the Flood in Halo 2 doesn't die. I stood for a half hour shooting the same Flood. It felt very satisfying. Then I realized you could hit them with a sword to blow them up, making the experience as mediocre as the rest of the game.

That and Episode 2 watching Eli die, ooooooooooooooh that Advisors gonna get a face-full of bullets.

YES.
I spoiled it by accident a little bit, but it was just 'Eli dies'. I thought I would be okay with that.
But then I saw it happen.
Jeezis Christ. Goddamnit, I LIKED him.

Thats the trouble with gaming forumns like this, Spoilers will eventually leak though

SPOILER!!!!!!!!

The end of Halo 3, Master Chief dies. Or so you think.
*Twilight Zone music*

Playing Silent Hill (PSone)
In the hospital, always those bloody nurses.
I'm scared of them till today, the way that they drag along
very slowly towards you and when they're just five steps away from
you, they launch at you swinging their blades viciously.

Lost Planet.

Playing it in Hard, walking into one of the Snow Pirate's levels while on a dare to beat it with a shotgun.

I looked straight at him and screamed at the top of my lungs when I noticed that I had somewhere around 10 people standing around me unloading on me with two mechs walking toward me, one equipped with rocket launcher.

Saints Row.

When the Mexican gang attacks the church, after mowing down waves of bad guys the huge dude that has been shown taking at least three bullet wounds and not even flinching, shows up in an SUV doing drive-bys on everybody, and then, after what seems like 80 bajillion bullets, the car blows up only for him to run out ON FIRE and needing another 80 bajillion bullets to die.

Kingdom Hearts II, when you look down and there are like 1000 freaking heartless...

Halo 3 Muliplayer Custom Game: Super Zombie, 16 people 15 of them zombies, fast zombies, all running in one direction... mine

R6: Vegas multiplayer, Taking cover behind a wall and the guy next to me peeks around... and gets sniped

legend of zelda ocarina of time, when you wake up to realize not only are you an adult, but that you kindof slept through the apocalypse.
It hits you when you enter in town square and see that all those happy people were replaced with ya-know, zombie things

In COD4, the Nuclear Bomb goes off while still in the helicopter and you see the guy right by you fly out

Engaging the Russkies in "Vacant" in COD4, explosions going off all around you, the enemy being killed off one by one, and finally reaching the red's bomb site. Then, looking out the window that spans the length of the entire room, and staring right at an enemy chopper not six feet off the ground. I say "oh shit" right before it guns down the whole lot of us.

I did not know that it could fly that low.

Last memory in Assassin's Creed, running towards the end and having about 27 guards jumping at me at the same time

-SPOILER-

Assassin's Creed again doing final assassination and realizing that Robert is a decoy.

I litterally yelled "WHAT THE FUCK IS GOING ON HERE?!"

Looking at a tank coming towards you in Battlefront.
Or anywhere for that matter.

Evaporated:
In COD4, the Nuclear Bomb goes off while still in the helicopter and you see the guy right by you fly out

+1

Realizing I've been playing this game for 8hrs without eating or saying something other than yea, na, or "wait to the next checkpoint, I'll be there in a sec"

Every time I hear that damn Metroid noise. You know which one.

TankaX:
Hey,

In Deadrising when i'm in the North Plaza and after i plow through all the zombies to the gun shop and then as i enter the crazy guy Cleaus keeps shouting at me and this other dude and the guy walks foward to the crazy and he gets shot in the chest and goes flying out the doors right into zombies...

Also in Champions: Return to Arms after i beat the shit out of four evil knights and the zombie a gaint door opens reavealing a gaint fucked up five arm thing and it's like 20x bigger then me!(When i finally beat it a mother fucking super gaint warlordcomes out and is 250x bigger then the thing and i thought i had to battle him... but didn't).

From, your friendly gamer TankaX

Yeah I rather diliked Innorouk. Though he was fun to pummel.

Playing the green slime level in Gradius V, thinking I was the world's biggest badass because I'd managed to avoid the green stuff that was merely *trickling* down from the ceiling, then watching the level rotate around me and realizing that a waterfall of that green ooze was headed right for my ship.

In CoD4 when playing search and destroy, and you dont hear anyone talk for a while,then hear that ur the only one left from the russian commander guy.NOT...GOOD...

TDM in quake 3. Charging for the quad and getting there just a little too late.

Also starting above the toilets in a proximity mine, facility multiplayer in goldeneye and hearing your mate snigger.

I have a couple. One was when I was playing HL2: Episode 2. During the driving section, when the fast zombie jumps down onto your car while you're driving. I was frantically clicking every button I could to try and shoot it until Alyx booted it out through the windshield.

The other was in Battlefield 2142. It was one of my first times playing, and suddenly I heard this steady humming sound that kept getting louder as I was running across a bridge. I turned and realized that this was the sound that the PAC hovertank makes. About a millisecond before the driver smeared me all over his front bumper.

Ouch.

That bit in COD4, where you're the Marine, and you have to navigate through that room with all the tvs and stuff, with the enemies also on the roof. On Veteran. That's bloody hard.

Then, there's 'No fighting in the War Room'. That whole section had me saying not "oh shit", more like "Not Fucking FAIR!". But, close enough.

Don't worry, he ain't really dead...

i guess my favorite "oh" moment in a good way would be in all ghillied up when MacMillan runs behind the guy and goes "oi, suzy" and just pwns him with a gun butt

In Portal, the first time I encountered those android things that shoot at you. I was all "What the crap, dude?! I don't even have a legit weapon to defend myself! All I have is this pissing gun that creates portals!" Hearing them talk made me giggle, though.

Jak008:
For example when, in the Bug Island for the Wii, the chick grabs that cockroach in the beggining.

Hearing that someone actually played bug island

COD4: Running through the corridors of bloc and hearing that ever familiar "click" noise.

Claymores.

Just about every single fight in Ninja Gaiden.
