one really cool one I haven't seen mentioned yet: enemy NPCs can shoot your SMG Grenades out of the air. it's extremely difficult to get it to happen but is most noticeable with combine shotgunners. if an enemy's bullet hits your SMG Grenades midair, it'll detonate immediately, often causing you damage. The SMG Grenades are proper physics objects.
@@asdawasda No it was a valid comment actually, shooters rarely have that kind of interaction of bullets and projectiles with enemies and player character, which is a very big thing in ultrakill
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.
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
i like how at all times alyx looks likes she thinly spread across both bodies and she just switches which one is her main body like shes some kind of hivemind entity
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
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.
@@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.
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
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.
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.
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.
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!”*
i don't know if this has already been covered, but it's one of my favorite little map exploits in Lost Coast, you can escape the map boundaries and actually visit Saint Olga there's a few guides for how to do it
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.
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.
13:07 I swear this teleportation sequences used to be harder . and enemies spawn from every blue laser gate and not just two . is this deja vu or i am going mad .

if you primary-fire the ar2 immediately after shooting an energy ball it'll spit out 3 bullets in a single shot as if it were a shotgun, and then go back to firing normally
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.
The very first time I played Half-Life 2 back around the time of the orange box, I got the double Alyx glitch on my run through Entanglement. Had no idea what could have caused it.
18:24 There is quite an easy and simple way of getting up there compared to bhopping. You need to bring props from the other room and stack them there to make a tower, you just use that tower as the middle platform to jump off of onto kleiners balcony.
I'll never understand how people figured this out. Surely must have been from accidental glitching out through various collective playthroughs as there's no chance to actually know to recreate this sort of thing from scratch.

I don't think the other Alyx can go through the teleporter. I'm guessing the game isn't really moving either one, and just loads a new Alyx with you in the new area.
Idk how but I manage to force akyx to move past the barrier on the second teleporter thingy at breen place. It's obviously smush her into the floor softlocking the game
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.
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.
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.
Would you be able to show a full video of how to get the twin "alexi" in normal play? I'm really curious but I can't find a single video about it anywhere on youtube.

Ah, some lovely early morning Half-Life content.
"Both Alexi", wonderful.
Alyxs in their natural habitat
It was incredibly brave of Alyx to sacrifice herself so Gordon and Alyx could escape Nova Prospekt. A tragedy for the books.
That's what clones are for
13:14
somehow i cloned her in the ghosting mod without even knowing this XD, lmao
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.
"Gordon! I had a feeling I'd find you here."
Gordon immediately turns around and flies into the ground

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

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

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.
The gunship was just there to kill Alyx to avoid a paradox.
