​@@Dr.FajardoPediatra well if I'm right, you forgot half life: source because from what I've seen blobs had used the "squeek" or "squeak" I forgot, but I just know snark models are named as squeek or something like that. But it uses snark models, but maybe hl2 contains the strange untextured snark and satchel charge models, oh yeah, from what I've seen, and I can't confirm because I play half life 2 in Garry's mod due to the fact that I don't have hl2 yet, but half life 1 items exist and NPCs from half life 1 exist too. For example snarks work, they are errors but they do function like normal and also, satchel charges do too. The thing is satchel charges dont have a model, and they don't even use the error model so you never know if you have thrown it or not, unless you get half life source.

A lot of those physics changes at 18:43 are fascinating. 2004 was pretty early on for physics-based games, and imo it shows that Valve really played the hell out of their game and could determine how to make HL2 "feel" right vs. just letting Havok do all the hard work

I just paused the video to see if there were any comments about this, particularly the buggy flipping over. It's like the game has the buggy weighted like a weeble, but it definitely can end up upside down outside the crane part if you get really "lucky". The engine will give it some assistance flipping back over, but there's still a threshold that the game doesn't cross, like when you flip the car upside down on some weird topography. And you're right, I was thinking that the playtesting was incredible very shortly into this.

[@novelezra]

Half Life 2 is one of the only games I can think of where it's only scary when you feel completely alone. There are games that are scary when you're alone, but they also try to hint that you're not really alone. But HL2 has moments when you are in broad day light, completely alone and it's fucking existentially terrifying. Like, I feel what it would actually feel like to be alone with nothing to think about except how everything is basically already over. It feels so real yet you don't want it to be. It's like when you remember a dream where nothing much happened but made you feel inexplicably melancholic. You don't want to remember that dream, even though nothing really happened in it.

Some random facts that I know of; All maps in half life 2 have sector names that the combine use, including the ones where the particular enemies don't appear in (metrocops in the citadel, for example). In addition, each combine unit has their own unique names and numbers. They also report target sightings in distance and degrees. The way they refer to Gordon changes, too, as he quickly grows in notoriety. The headcrab zombies have an unused behaviour for detaching themselves from its host voluntarily Combine soldiers have unused ACT_ animations for lobbing and dropping grenades. They work properly if you force them to play the animation. The synth scanners act as scouts for striders - when they take a picture of you, the strider becomes aware of you. Metrocops have an arrest behaviour for first encountering the player that goes unused. All ai have a "sixth sense" that can be triggered by map makers to have npcs react to things they'd normally disregard. The public github fork of half life 2 has the cpp file for the combine assassin available (Meaning it should be legaly possible to use?) The combine APCs can be entered if you unlock them. These can't be driven yourself, and you can't get out once inside. The combine cameras panning back and forth is actually not what's intended most of the time - they should be looking at specific points on the map when idle, but this behaviour is broken. Antlions have unused animations for a "charge attack". I couldn't get it to work. In antlions soldier's code, it's noted that the antlions instakilling combine soldiers is a temporary solution until a proper animation is added. The dynamic interaction system for animated kills wasn't finished until episode 1. Snipers have soundscript entries for scanning, attacking, being idle, and being frustrated. They would have been refered to as "scalpels" in their terminology. Combine helicopters have an unused flag that turns them into a drone of some kind? Idk, I don't remember clearly. Striders have an animation for sleeping In one of half life 2's trailers, a shoe glitches out when a rebel walks over it , and dies off-screen There's code for dropships being able to drop APCs (I picture a mako-style enterance, from ME1), but the apc gets stuck in the dropships when it's attempted. The gunship has a functional "ground attack" that never goes used. Combine shotgunners fire faster than is physically possible due to a coding oversight. The npc_citizen_insignia variable gives chef hats to citizens when they are in your squad. Edit 19.10: In 2017, the VMF files for all retail maps got leaked. In these map files, there are unused filters for two "hallucination sequences". The first one happens in the first level of route canal, right at the start, and seems like it would have scrolled a bunch of textures in front of your face, and then dissappeared (Similiar to what happened at end of 2003 E3 demo.) The second hallucination effect happens in sandtraps, at the long zombie infested tunnel,and it seems far more complete. Entities related to this scene even exist in retail!

The "right click weirdness" is mostly just the secondary fires being out of ammo, so it's trying, and failing, to shoot the secondary while you hold down the primary. I think the weapons that don't have secondaries that still do this are just a byproduct of clunky coding.

Another fact: If you have the HEV suit and walk over a stun stick, it'll give you a bit of suit energy. This can only happen once, when you encounter the two metrocops beating the lady's husband, that is the last time you encounter stun sticks in the game.

[@techleontius9161]

Oh... This is why the box is not just a prop, but a separate entity! I actually never believed that any HL had changing power up placement, since the level designer puts the box himself.

[@gabrielandy9272]

its still good map design the fact that the item changes based on you need is good GAME DESIGN. the game still have STATIC spawns with a box that will provide waht u are needing, that way a player that use more shotguns will get more shotgun shells etc.. it makes more sense they are still limiting the things that can adjust in the game as its just a few items that can turn not all.

[@theshinken]

One of the most fun times I had with Half Life 2 was playing Co-Op in earlier versions of Synergy. You had to fight against bugs almost as much as the enemies and at some points the game would go totally haywire into some strange glitched alternate dimension version even if you made it to the next level. We have laughed so much in teamspeak because of that crazyness and came up with really creative co-op solutions to showstoppers that seemed impossible to overcome at first glance!

38:04 In GMOD I would toss an explosive barrel, catch it with the physgun, freeze it in the air, and make it invisible with the color tool. It's a land mine for other players to run into :D

[@JsphCrrll]

Fun fact: In the first episode, after you put the can in the trash, there will be a part where you climb a ladder to get over a fence in an alleyway, and from there you take a left or right. Taking a right progresses the story. Taking a left you'll see a bunch of CP in the middle of arresting a couple of people. Getting too close will result in them stunning you after a few swings, as per usual. One if the CP will block you from interfering with the situation, but if you lure him to a dumpster and have him smack you at just the right angle while you are standing on it, you'll be sent flying into the air at varying heights. Since this is the very beginning you don't take any fall damage so you can get up top on the building's and explore around without the CP killing you. I haven't been able to really find any practical use out of doing this, but feel free to find something I didn't. Btw, I did this playing "The Orange Box", and I'm pretty sure it runs in an older version of HL2. So I'm not too sure if it works on the latest patch.

A little Fun Fact about the falling explosives glitch at 38:05! If you use the Gravity Gun to shoot explosives at a friendly NPC, they will not take damage from the explosion. But, if you perform this glitch, they will take full damage! Glitched explosives will also explode even by gently brushing them against something; it doesn't require any momentum or force at all to trigger it. You can use this method to kill Colonel Odessa before getting the RPG since there are so many explosive barrels in the area. Even though it shouldn't be possible for Colonel Odessa to die, killing him still triggers the game over screen, similar to when Alyx or Barney die.

Fun fact the dropship gun bug has been fixed as of late, so now the level is actually challenging.

[@megakarlachofficial]

yea, through this bug still remains on Xbox 360 because it was never updated. Plus this bug was first present in the X360 and PS3 version of the game when it was released back in 2007, which also later affect the PC version aswell in 2010. Even through the bug is fixed in the PC version, some sourcemods that rely on the Source 2013 Singleplayer/Multiplayer does not have this bug fixed.

7:10 Here is a quick explanation on why is this happening. The crane was made in that scene so whenever it picks up something else which is not the buggy, it will break it. Usually it's done by some complicated output or relay technology. But when you put something that is NOT breakable, it breaks it anyway because of the triggers, except the particles don't appear this time because unbreakable props such as the barrel are not coded to have any breaking particles. Hope this solved some of the questions you might have had.

[@GIJew]

5:00 I knew I wasn't crazy. I specifically remember that part being next to impossible the first time I played the game. I recently played through the game again and wondered why I was able to just go all the way up to the ship and just pick them off one by one as the jumped out before they even had a chance to shoot me. I knew something was off lol.

Making supply crates drop the most needed thing is extremely smart. This game is so awesome.

That was the ONLY fact/glitch I knew in this entire thing. I feel like I've always known that somehow even before I got a PC that could run HL2

[@wetwayne1504]

I don't think this is the only game that does something like this. I distinctly remember the Ratchet and Clank games dropping different kinds of ammo from crates depending on which weapons you are missing ammo for.

[@farawaygaming_]

half life alyx does that too, but i only knew about hl alyx doing it. i never noticed it in hl2

[@Templarfreak]

it actually was not in the original base game, it was introduced in EP1 and then retroactively patched into base HL2, and even then from what i recall only some crates in base HL2 do it, not all! its a special type of contents that crates can have, and they didnt change all the crates in base HL2 to have this special new contents, some still have their own pre-determined content.

00:59 more accurately, the airboat looks weird because you're never supposed to be outside the airboat when it is in the air (it only moves that fast when you're inside, and you can only get out when it's not going fast). The airboat falls slowly because of gameplay reasons, and the gravity gun is working just fine. The super gravity gun, though, is a lot more broken when it interacts with the airboat. You'll create a copy when you try to grab the airboat with the super gravity gun, and punting the airboat creates a ton of lag if I remember right. 38:50 WTF?

38:04 i remember seeing a very old gmod guide that used this exact glitch to make "landmines", basically punting explosive barrels up into the air and then easy welding them to the ground basically, anyone who walked into them would blow up immediately

[@MildMisanthropeMaybeMassive]

23:30 You can also reach G-Man in New Little Odessa. In my 2nd or 3rd playthrough I somehow managed to avoid tripping a trigger probably with my reckless driving, and reached Odessa Cubbage and the Gunship battle. G-Man remained on the destroyed upper floor with a second Odessa Cubbage while another Odessa Cubbage remained in the basement. I also managed to get two different Alyxes in Anti-Citizen One in the wave fight to open up the Combine wall where Alyx deactivated the shield so we could punt the plasma orb out. She didn’t get to the wall gate before it closed on her so another one spawned. I also had this happen in the Citadel in Ep 1.

[@FriendlyKat]

This is super fascinating! It’s like a BTS of how games work (or don’t) Thanks for sharing this awesome video! It’s super cool to see how some stuff won’t trigger if you just don’t look at it! 49:22 Spinning combines are a thing of beauty.

[@CrimeEnjoyer]

"ep3" is an alphanumeric name unfortunately. Two letters and a number is a common naming scheme in valve code. The blob ally was cut and replaced with the antlions, which originally were just enemies and written to be controlled by the player much later. Some of the programming from the blob was reused for the antlions, which is why there are weird interactions between the two.

[@magnusm4]

13:01 O_0 Those are freaking amazing for 2006! That swarm ai, the blob texture melting together and that beautiful rain. Can't imagine what it would be like to optimize it further today. That swarm would be super insane as an enemy or feature in Half Life 2! So much visual flare could've been added to both the gameplay and visuals.

I've remembered something similar of what happens in 21:14 can happen in Resident Evil 4, but it's not by looking, it's caused by avoiding a trigger. On the last chapter in the game, there's a time where Leon needs to go through a prison cell corridor and there is a regenerator inside the last cell on the left, that gets triggered by you walking on the middle part of that corridor. But if you hug the walls on the left side while walking through it, you'll be able to stay face to face with a regenerator just chillin inside the cell, and it won't attack you as long as you don't trigger him **spoopy**

[@owenshark24]

With Valve finally updating HL2, EP1 and EP2 in preparation for Steam Deck’s release, I wonder how many of these bugs will finally get fixed and how many of them will remain under the radar.

[@sharp14x]

Finally, glitches and facts about Half-Life 2 I have a low chance of having prior knowledge of.

[@bjornroesbeke]

I'd consider many of these things to be bugs but often it shows the time Valve spent playtesting to make sure the game stays fun. Iirc, there's something said about it in the developer commentary, somewhere there's an arrow constructed to make the player look up. The same is true in other games such as Portal, where Valve (for example) places the right portal colour, even if you clicked the wrong button.

[@TrumanFritz]

[@Milkbutter]

Might only be old versions, but you can "drive" the NPC at the window when the raids first happen in the apartments on the first level. Because it has buggy physics, picking it up with a Super Gravity Gun will crash the game.

[@SkyWayMan90]

It’s subtle, but I appreciate the way you worded this title :)

[@emericlarochette]

You basically just made the best multi-ticket ever for Valve to fix HL2 glitches. Apparently they are updating the game code right now to make it Deck compliant. They should use your video as a ref to find and squish some bugs in the meantime :)

[@dafurious6457]

in the part where your items get taken away and your gravity gun gets supercharged, if you run to the force field and stand next to it when your items get taken away from you you can sometimes get the rpg to clip through the force field and it will not be destroyed, allowing you to use it when you normally would only have the gravity gun.

I remember years ago playing half life 2 on the classic xbox, and decorating buildings and houses. I understand when you carry an object from one map to another that object dissapears, because of memory stuff or whatever, the xbox version was no exception but still in some rare ocassions the object would load to the next map. Even heavier objects you could not carry around like couches. The other option was to save before moving to the next map and after.
