14:35 Plot twist: Mossman actually mean it when she says "what are you talking about?" because the glass is so thick she couldn't hear Alyx clearly.

[@Palexite]

Mossman: “I’ve worked to protect your father.” Alyx 2: [takes a hike all the way to Mossman] Also Alyx 2: *”S H U T U P A N D B E G L A D Y O U R S T I L L S O M E U S E T O U S!”*

[@AVeryNervousWreck]

The way she casually walked all the way over there just to say "Shut up and be glad you are still some use to us" 15:26

[@Konxovar0]

I like how when the sequence in the Mossman interrogation the second time over switched Alyxi, Mossman just stood there until Alyx walked in and told her to shut up.

[@trashrabbit69]

The aggravated expression as she strode over, only to teleport three feet to get past her clone only makes it funnier.

[@mhetralla]

It made Alex's next line more intense. 😆

[@rompevuevitos222]

A nice reminder of the response system of the Source engine, where characters only speak when another one says something to them or change their dialogue depending on what's been stated Even TF2 uses it

[@Michi_Exiled]

"Its possible to avoid getting the water gun" ah yes, family friendly version of HL2

[@AverageMichaelJordans]

I still think the first showcased trick is mind blowing. Not because it has a cool result or anything, but because despite all odds it's a thing you can do. You can leave half way into a cutscene, and then go back through the level with the airboat into the previous level, and then leave the airboat there, then come back and finish the cutscene, then go get the airboat again. Stuff like that is what makes Half life and the source engine so batshit insane, you just can't do shit this stupid in other games, I love it

[@ThisUsernameSystemF-ckingSucks]

You can skip getting unbound in skyrim by goingnover a wall. You get sinilarly stuck too lol. Although you can go back and fix it. A lot of games have these soft locks by skipping triggers in some way.

9:17 Alyx’s existential nightmare begins

[@DanielWindows]

imagine seeing your clone

[@theengineer-dellconagher]

i wonder how the game decides to choose which alyx plays out the stuff for cutscenes

[@rompevuevitos222]

Whichever was spawned for that level specifically One is a left over from an extra spawn, the other is the one the game is actually using The animation's timing is handled by the level, not Alyx herself The game already chose an Alyx to be the main actor well before they even spawned to be the actor who will use the animations, probably the first one

[@MolkoKillStyle]

Its interesting how they use the multi-tool at the same time to hack doors

[@cstr2454]

I assume they have different methods to access entities and they may not use the same ones across all scripts - i imagine that one might use “targetname” which possibly means it picks the last Alyx that got spawned in (because there can only be one entity using that name in the world). The other method might be looking up entities based on their class name “npc_alyx” (I think) and just find the first one and use that. All just speculation, I haven’t looked at the code to know for sure.

[@theengineer-dellconagher]

@@rompevuevitos222 i noticed that the alyxi sometimes switch between each other doing the cutscenes though

[@AsG_Alligator]

@@cstr2454 Correct, scripted_sequence entities can either use the targetname to play a scene on a specific npc, or use the classname (eg. npc_alyx) in which case scripted_sequence will pick the closest npc of that classname to it. It all depends on which way the level designer picked for a given sequence entity.

7:47 On the OG xbox version i was able to get Alyx in there as well as getting the duplicate, I honestly don't know how I did it tho as that was years ago.

[@Pinsplash]

someone else also said that. maybe at one point it just happened regularly.

[@caramelldansen2204]

amazing profile picture, yowai :3

[@paskaalisaapaskaa5354]

On the OG xbox version, if you carried a turret from the first turret segment to the teleportation room, the turret would consider Eli and Mossman as enemies and then gun them down. After that you couldnt progress because it breaks the script i think. Anyway, it thought it would interesting to mention since i wasnt able to recreate this bug on PC.

[@aurele2989]

10:30 Having studied some ancient languages, I'd guess the plural of Alyx would be Alykes.

3rd time commenting that it's possible to skip the train entirely in Highway 17. The trigger doesn't extend all the way across the bridge, so if you use showtriggers_toggle, you can use the momentum of the buggy, as well as timing, to get the buggy over the trigger but not yourself. Then, jump over the railing and either strafe jump or just squeeze around the trigger.

7:39 I actually had this happen to me before legitimately on the original Xbox version. It was a bit farther up ahead (different part entirely maybe, been a while), but it ended up being really annoying since one of them couldn't defend themselves, and if they ended up dying, I'd lose. So I had to cover her just so I could move along. Weirdest part is I have no clue how it happened. I didn't sequence break or anything. The Xbox version is weird =~=

Fun fact: you can use the barrel in that one puzzle part behind the airboat gun cutscene as a use-hop glitch, so you can save HP and armor battery you had.

Odd that there's enough of a navmesh under the water for the Antlions to run around

[@Pinsplash]

>No nav mesh in HL2, it uses nodes >they're using local nav which is very simplistic but doesn't require nodes

[@The_Butt_Cracker]

The opposite is true. The fact that there _aren't_ any pathfinding nodes in those out-of-bounds areas is why the antlions have trouble reaching you there as pointed out in the video.

[@oberon_2800]

I found a glitch on the Xbox One backwards compatible version in Nova Prospekt. I found that none of the turrets disabled themselves and remained active throughout the level. They also became confused as the level went on over what targets were friendly or not. By the time I got to the teleporter, three of the turrets were shooting at Mossman but she was invulnerable. Then when Eli was brought in they started shooting him and he died in four shots and it completely softlocked the game. I recorded the last part.

I am confused, the antlions can atack and spawn on an out of boundry place (there are no nodes points for sure) but in a different video the couldn't jump up atacking you on a building's roof due to the surface lacked any helping node point.

[@chocofrolik834]

Because the game is coded to spawn anylions around you if you step on sand, and he was stepping on sand

[@weigurde]

what choco said, and also the antlions are probably using the nodes above them; this might be why they randomly stop coming after the player, since they don't see nodes where they're jumping.

[@mechspace]

Local pathfinding does this. If you go into GMod and spawn 2 opposing side NPCs on a non navmeshed map they will still move around to shoot eachother but only in a close proximity as the AI estimates where to go. If you spawn them far away they won't know where to go due to the distance being large and will have to rely on navmeshes or nodes. Since the antlions always spawn at your location they can use local pathfinding to attack you.
