Behind the Scenes Gaming - Half Life | Slipping Out 

1:47 "You think this is the right way out?" ............... "Shut up." LMFAO!

10:30 Regarding the character models: Actually, the first security guard is not the original you showed. The one you showed was actually from an HD repack that came along with Half Life: Blue Shift. Originally the guards (and many other models) were just like the Source version. However, since even the HD repack is older than Source, there should have been some improvements, now that you mention it...

The "hideous" models from the Source version are the originals from the GoldSource version. You just have the HD pack on it.

A little bit regarding the rocket launch sequence at 12:50 - The reason the rocket is kept in a separate box and only then teleported beneath the launch pad is due to GoldSource's lighting system. GoldSource uses static, pre-baked lighting for levels, and dynamic lighting for models, which is why you'll see muzzle flashes light things up, very impressive for 1998! The rocket is a map entity, not a model like NPCs or weapons, so it follows the same rules as the rest of the level, and is only lit once, when the map is "compiled". This has special cases, such as lights that can be toggled by the player - they are rendered once for each state, and the larger the area being lit is, the longer the map compilation takes, upwards of hours considering the hardware of the day. For that reason, simulated natural sunlight is only allowed one instance. Since the launch sequence is a nighttime scene, Valve wisely used the environmental light to create the right ambiance. The rocket needed to be well-lit and visible both to support the other launch visuals, and to draw the player's attention via contrast against a dark background. So, the rocket was built in a brightly lit box outside of the main map, and then turned into a map entity known as a func_train, a generic platform capable of following waypoints in sequence. These waypoints allow for skipping movement altogether and teleporting to the next waypoint, so the "track" the rocket follows begins in the box, then teleports the pre-lit rocket down below.

10:20 The half life source is just a port, and the original half life look better because you have the models remastered by gearbox

Hey Everyone! The awesome Half Life is a game I've wanted to look behind the scenes of for years now, however I felt that just using the well known built in console 'Noclip' would be a let down (As I'm sure many of you have already done this). So I've gone ahead and given it the special Slipping Out treatment. Therefore in this episode you'll see such scenes as the Grunt capture scene and how teleportation works, plus more, as you may never have before! I hope you enjoy.

The boxes during the tram ride were used as a light source for the tram itself Also the models in half life source are the non HD original retail models, they can be seen in half life non source by going to the video options tab and un-ticking the hd models box

The boxes in the intro section are used to store the train, before it gets placed on the track. The reason is, how GoldSource (HL1s engine) and Source render lights on so called "func_tracktrains" (a train which follows a pre set path). They're made of "brushes" (so like normal level geometry). However Brushes are only getting one light and shadow pass while the map gets compiled. So if you place a tracktrain in a dark area, it will always appear dark, even if it moves to a well lit area. To compensate this, Valve placed the tracktrain in a seperate room, with lights on every side, so the train gets nicely lit during the compile of the map, then gets instantly placed on the track as soon as the map starts.

*"Awww you cut the ponytail"*

I really love your content, I just wish it didn't always trigger my existential dread 😅

These videos are always so fascinating. Your chipper narration just adds to the enjoyment. Keep up the good work!

sometimes the assassins' goggles flip up on death and you can see their eyes.

What an amazing game half life is, thank you for this video, is so satisfying to watch.

I have to say these videos are really entertaining - not only from a players pov but also from somebody who has gotten to see a bit of game development as well during Uni. It's always fascinating to see how much of a game is actually just smoke and mirrors and paperthin walls. Best example are the guns. Of course once you mention it, it absolutely makes sense to not render them fully - especially if you think back to the time when Half Life came out. The skybox thing is the same - very interesting how they did that and still, it absolutely makes sense.

Awesome as always. Literally any1 can use no clip but u went 1 step further Slippy. Not even sure how u did it especially showing the weapons n teleporting stuff. Great job

10:43 "Hey beautiful! How're you doing?"

Fun Fact : The level c0a0d (The area before the "In the Barrel today" cutscene) contains an earlier version of the Anomalous Materials lab entrance hall. This one is much more industrial-looking and has brown airlock doors. Interestingly, the brown airlock doors are still used for the entrance to the entrance hall in c0a0e, which contains the proper entrance hall. tcrf.net/images/thumb/f/fd/Hl_anom_entr_c0a0d_1.png/600px-Hl_anom_entr_c0a0d_1.png tcrf.net/images/thumb/2/2d/Hl_anom_entr_c0a0d_2.png/600px-Hl_anom_entr_c0a0d_2.png

Cant believe Coomer lied about the being nothing out there smh /s

Slippy's videos are really quality stuff.Great thing.please do someday Alyx.

The Gabe face box must be too make the enemy go insane before going after the player😂

8:43 This types of island outside the map are always present in every single game made with the source engine, like Half life 2, CS ,CS:S, CSGO, Left 4 dead, Team fortress, Portal and more. IDK why they even exist

Amazing content! Keep making my days better ❤️

Awesome video as always 👍👍 Super excited about the Assassin's Creed & Mafia!

OMG! Can't wait for a video on Mafia!! That will be the day. Also thanks a lot for this one! It was really interesting to see behind the curtains of some scenes and places from my childhood.

Did you say MAFIA? You mean original one? I can't wait!

12:20 got emmmmm

4:38 I thought there was a very, very powerful explosion, which broke the anti-mass spectrometer

If you try to pull the crystal out of the beam immediately after you insert it, a Vortigaunt will spawn in the test chamber.

The models look worse in Source because they're not using the HD models from Half-Life, but the original Half-Life models.

11:09 Don't know why you can't see into the G-Man's briefcase in HL there, I seem to recall it would be visible by noclipping like that. But those textures are in the G-Man's texture file.

They're waiting for you, Gordon. In the Test Chamber. I'm afraid we'll be deviating a bit from standard analysis procedures today, Gordon. Yes, but with good reason. This is a rare opportunity for us. This is the purest sample we've seen yet. And potentially the most unstable! Now, now, if you follow standard insertion procedures, everything will be fine. I don't know how you can say that. Although I will admit that the possibility of a resonance cascade scenario is extremely unlikely, I remain uncomfortable with the... Gordon doesn't need to hear all this. He's a highly trained professional. We have assured the Administrator that nothing will go wrong. Ah yes, you're right. Gordon, we have complete confidence in you. Well, go ahead. Let's let him in now Testing...testing... Everything seems to be in order. All right, Gordon, your suit should keep you comfortable through all this. The specimen will be delivered to you in a few moments. If you would be so good as to climb up and start the rotors, we can bring the Anti-Mass Spectrometer to eighty percent and hold it there until the carrier arrives. Very good. We'll take it from here. Power to stage one emitters in three...two...one... I'm seeing predictable phase arrays. Stage two emitters activating...now. Gordon, we cannot predict how long the system can operate at this level, nor how long the reading will take. Please work as quickly as you can. Overhead capacitors to one oh five percent. Uh...it's probably not a problem...probably...but I'm showing a small discrepancy in...well, no, it's well within acceptable bounds again. Sustaining sequence. I have just been informed that the sample is ready, Gordon. It should be coming up to you any moment now. Look to the delivery system for your specimen. Gordon! Get away from the beams! Shutting down. Attempting shut down. It's not...it's-it's not...it's not shutting down...it's not... * Scientist screams * Yes this is my favorite copy pasta thank you :)

Great video slippy:)

3:27 "Who are you!? No... I don't wanna be a schizophrenic!" "Oh my god... This is crazy in a handbasket with a side order of fries..." Hope someone gets this old reference :D

That rocket came out like a poop and they used the same technique as goldeneye on those weapons.

The OG models were effin monstrous

Oh Jesus, that face room! 😲😲😲

Wow I’ve just now remembered about your channel i remember watching you years ago when you did bo2 and bo3 vids

Good timing, I'm currently playing Black Mesa lol

Future episodes yessss hurryyy! :D

Thanks for making this series

always good content:) ..i'm waiting for the mafia episodes though

This was awesome to get.

Blue shift u play as the guy hitting the door I think

Once in the sand buggy I rammed every small vehicle and (car wrecks) past the place where you lift the buggy with the crane and piled them and all loose mats from the bridge area in front of the train on the bridge. After activating the train I watched it go right through the pile of cars trucks beds tables etc. After the train sequence was over I went over to the pile of scrap and though somewhat in tacked it was rearranged, quivering and smoking. I walked on top of it and was immediately lunched into space. Bridge highway, the entire area dwindled beneath me :) I think I landed in the river :(

I don't what it is but when I hear your voice it just makes me relaxed

Hello Gordon!

@Slippy Slides can you do call of duty advanced warfare because I always wonder what’s outside the map. Can you do campaign outside of map

Nice vid

Love you slippy

I love half life

8:15 why does the floor do that? i see it in plenty of other games but i don't know what it is or why it occurs

The character models in Half-Life source are Just non HD models but half life you are using the HD models

I hope one Day you Will cover Cry of Fear... A marvel among HL enthusiasts and an amazing horror game.

Make a video about RtCW

You should do Half-life 2, it has some fantastic "out of bounds" stuff :D

1:44 Crappy einstein?

cool

can you do Black Mesa too😀

Yeaah !

PLEASE DO AN EPISODE ON DEAD SPACE 1!!!

counter strike next?

Thanks! Would you please do Soma

💙💙💙

Have u ever done outlast whistle blower dlc before I would love to see that and also monstrum. 🙌😊

Next Half Life 2

There's no way HL Source has lower resolution textures and less polygon for character models. Also, you could have included the scientists in the toilet, otherwise interesting video.

I’d love to see call of duty 3 that would be cool

your version has different character models, must be some mod

This is so awesome that you showed so many new stuff that I've never seen before on YT, this was indeed very interesting. To your question what's better, I'll say that the source engine is horrible in my opinion, I love the original Vibe where everything is a little bit pixelated, it gives me a lot of nostalgia where I played half life with my big brother 😂💜 keep going with your work, I'm excited for AC *.*

15:28 Aliens like: what the? A flying cam?! XD

you used the hd models from blueshift these are not made by valve - redo video

14:49 the way you sped up the video makes me wanna add text "average x fan" where x is whatever is funny, be it "employee" or whatever im just bad at joking

vhen new gta sa vid?
