Everything that has a rock background.
I luv the rock skybox, I probably won’t like BM just because it doesn’t have that rock skybox.
HL: Meeting G-man at the end of the game. Killing the Tentacle.
HL2: Playing with DOG. Anticitzen 1 in the ruined buildings chasing a single combine soilder only having him eaten by a barnacle.
HL2EP1: Lowlife (not in a good way). Zombie Hospital.
HL2EP2: Running through antlion tunnels with Craig the Vort. Driving the hotrod. Magnisson relating back to the oven lucnch
My favourite moment would have to be in Episode 2, when you’re inside the White Forest Inne, with Combine soldiers and Hunters shooting through the windows at you, and you shooting back. Then suddenly the music subtly changes, and the soldiers and Hunters stop shooting and start running around outside, and the flat, emotionless voice of the Overwatch Dispatcher filters in and Alyx gasps in horror: “Listen . . . they’re talking about us!”
Truly epic. I hope we hear more of the Dispatcher in Episode 3.
HL1 - Emerging from the vent to that awesome cliffside vista in Surface Tension. My favourite moment from any game.
HL2 - Being “on the run” at the beginning across the rooftops just before you meet Alyx the first time, and after Kleiners portal fucks up and you have to take out those two Civil Protection guys with a crowbar. The music just pumps your adrenaline right up. Its great gameplaying.
And the invasion of Nova Prospekt. The chaos everywhere, gives you a warm glow knowing its your fault. And Breens looped speech “This isn’t some agent provocateur or highly trained assassin…”
HL2Ep1 - The fight with the gun ship in the attic. I like the way Alyx is shocked at what a badass Gordon is.
HL2Ep2 - The siege at White Forest Inn, and the car in general. And the Aliens-esque siege with the turrets and antlions.
HL- the rotor puzzle
HL blue shift- Shooting at the shooting range.
HL OP4- Meeting the first group off allies.
HL 2- Seeing the light on the end of the tunnel from ravenholm
HL 2 Ep1- Killing the strider.
HL 2 Ep2- Dog kills strider.
Favourite moment: The end of Episode 2. Made me cry actually. There were real tears in my eyes. And it’s not easy to make me cry. Proves to me that this is a great game. This is only the second time I have cried because of a game scene.
The other one was in The Witcher. Must have something to do with the immersion. I was drawn into the story so much that I actually felt with the characters.
Great voice acting for Alyx in that final sequence of Episode 2, I think. That was movie quality in a game. Loved it.
HL1 - Teleporting to the Nihilianth’s chamber and looking up at the huge fucker.
Blue Shift - Escaping to the jeep at the very end.
Opposing Force - Boot Camp! Ooh Ra!
HL2 - Seeing the Fast Zombies scaling the buildings of Ravenholm and watching them leaping across the sky
HL2 EP1 - Encountering my first Zombine. Sweet.
HL2 EP2 - When Eli dies…
HL1: Killing the scientists with Impulse 101
When you press the button that makes 4 scientists fall to their death in the elevator.
OP4: Boot Camp, that was funny and awesome.
The chance to play as the opposition
Blue Shift: You play as Barney, that’s all you need to know.
HL2: The Civil Protection sequences…(Pick up the can, Them closing the door when you peek)
HL: Near the start, where Headcrabs begin to teleport in, one of them ends up in one of the glass containers lining explode-y computer aisle. Looking at it made me a little nervous
Blue Shift: All of it. <3 Calhoun (And peeks of Freeman)
OP4: Otis. To be honest I wasn’t too keen on the rest of it 
HL2: Nova Prospekt - listening to Breen give a rollocking to the forces for not being able to grab Freeman. Also “IF YOU SEE DR. BREEN, TELL HIM I SAY F------”
EP1: Waiting for that bloody lift while being attacked by god knows how many zombies. Erghhghgfjdhd
EP2: Dog Vs. Strider
They kept spawning, so now matter how many you killed, more would be there fore you. :fffuuu:
Then they freaking made it so if you turn off your flashlight and there’s no light, a zombie spawns about 10 ft away from you. :evil:
Forgot one:
I don’t know which one this was - somewhere in HL2 or the episodes you are underground with Alyx, with headcrabs and zombies about. It is dark, and when you first have to turn your flashlight off you hear a sound near you, a moaning like from a zombie or something. I actually got scared and turned the flashlight on again, only for Alyx to be snickering: “Ha, I got you!” 
I would have fired three rounds at her feet.
“Ha, got YOU.”
Hard one for me since games actually touch my feelings only in the form of humor (good joke like Eli’s Gordon+Alyx=Babiez-joke etc) but I think the whole Water Hazard (the helicopter was awesome and it had the music from HL1 and HL1:OF=fucking awesome) and the last 30 minutes of Half-Life 2 \m/ Pure gold
And the ending music (remix of the old ending music) was great and a nice surprice in the end
Second that! The soundtrack playing in the background and the jet flying past made it totally epic!
Half-Life 1 - Right after the Resonance Cascade, seeing all of the destruction of the places you were just at moments ago.
Blue Shift - Going down the elevator at the beginning and seeing the amazingly scripted crash.
Opposing Force - Killing those damn assassins.
Half-Life 2 - Nova Prospekt, Anticitizen One, Ravenholm, hell I liked it all. And I especially liked killing Big Brother- I mean, Dr. Breen.
Episode 1 - The Hospital and the Strider battle in the train station.
Episode 2 - The very beginning, driving the Jalopy through the train tracks and seeing that damn Fast Zombie jump on my hood. Also encountering the Advisor at the barn.
Or you could turn the flashlight off and hide somewhere. After a while she starts saying things like “Are you still there?” and “Don’t leave me here!”. It’s quite amusing, in a cruel sort of way.
When playing HL yesterday, I came across a place in Surface Tension I had forgotten about… When you kill the second Gargantua with the air strike… aiming everywhere and bombing the crap out of the place was awesome. Probably not my favorite moment, but awesome 
I wish there were more stuff to blow up there, though 
hl:the cliff with the jets flying by
op4ce:being left behind
bs:nothing,it sucked
hl2 :s troming the nexus
ep1:the citadel
ep2:the start in the train
why does everyone love route anal?it sucks
no u
Route Kanal is great game design and fun as hell to play. For a example, how about the fact that practically none of it is actually time sensitive in the sense of punishing you for stopping or going slowly, and yet it manages to induce a sense of an adrenaline-fuelled chase with you always just one step ahead of death.
This.
And, despite being in the same kind of setting for a fairly long time, there’s a lots of variety.
