19:35 "Valve *really* knows how to do a sequel." Yes. Valve knows how to do *A* sequel.

"One of my favorite tropes is a robot with personality." You're literally playing the best game possible for that trope lmao

"We both said a lot of things you are going to regret" Such as awesome line.

At the end of Portal 1, after you end up outside on the ground, it used to just fade to black. It wasn't until they started working on Portal 2, they actually updated Portal 1's ending to include the bot dragging you back off to the facility, while thanking you for "assuming the party escort submission position."

Most of the questions you asked about the first game are answered in the director's commentary version of that game, they enrich the experience and don't spoil the sequel at all, so worth a look.

I like how they replaced a slow Energy Ball mechanic from the first game with lasers one and at 47:30 you can see the Energy Ball nest slowly leaving the room, like Valve straight up telling "Yeah, forget about this one"

I love Glados' voice acting, "Oh 😊 it's *you* 😡"

One thing that I absolutely love about portal is it's musical direction. They're very interactive and common parts such as lasers and aerial faith plates have their own musical notes that play into some tracks.

Game: extremely funny joke Mapo: hmm, let me think about the lore implications.

39:56 Fun fact: One of the working cd keys for retail Half-Life 1 is all A's. Also don't forget to play with Steam achievement notifications on!

I like how the first one was "we're just going to start out with a generic game and then very gradually give you bits of story throughout until the end," and this one is "BOOM, ALL STORY OFF THE BAT!"

The coop campaign is _so_ worth it, but there's a non-zero chance of finding out your friends are actually complete monsters while playing it :D.

"They are sentient, of course. We just have a lot of them" This game just has so many gems, the writing all the way through is absolutely astounding.

All these years and I never noticed the phases of the moon on the ceiling of the mural room. Awesome.

Love how it prompts every player to stare at the art, yet in the next scene where the art is different, almost nobody ever notices

44:55 I find that often there is a linguistic gap that makes it difficult to discuss horror. As I see it there is: terror: the thing that happens when the big scary monster is chasing you (or the axe-wielding maniac, or the kraken's tentacles wrap around the ship, or the bus sized hailstones crash into nearby skyscrapers). Something awful is happening in plain view and it terrifies you. dread: the feeling that something really bad (possibly terrifying, see above) is about to happen horror: the creeping sense, scratching at the back of your head that something is very wrong, or that you are not noticing something important (like a terrifying monster lurking nearby) So, we have horror in the phase where you notice that the forest around you suddenly grew quiet. Then dread when you hear and see the rustling leaves of that there bush. And then terror when a bear rears up from behind the plant and roars at you (or simply charges at you). Good horror plays with these three elements. You want to perpetually build up the horror until it becomes this choking oppressive atmosphere that feels like grease coating your tongue, like a drop of water stuck in your ear; you want to amplify that horror by teasing with dread, stop short of the scare (terror) a couple times until finally you do one big terrifying moment when the monster finally appears and it almost comes as a relief from that oppressive atmosphere of the horror. (The horror is lost the moment the monster is plainly revealed, when you see it, you are no longer missing that crucial information that brought about the sense of horror in the first place) There's nothing all that terrifying about GLaDOS, but she is fairly good at playing with horror and dread mixed in between the humour.

Remember to explore a lot. There is a lot of secrets hidden throuout levels, especailly extremely large ones, though smaller ones also have something hidden in them. Also, if you're in damaged testing rooms - it's worth to check out any 'cracks' in walls, floor and ceiling.

Wheatley being voiced by Steven Merchant was a great idea

fun fact: portal one was very much an experiment and they didnt really expect there to be a sequel at the time. they actually retconned the ending for portal 1 after 2's development started. in the original ending, you just laid out on the surface with debris from the facility raining down and it faded to black, the implication being that you actually escaped and that was the end of it. they updated it to have the party bot drag you back. which caused some confusion with some of the original -players- test subjects when we found ourselves back in the facility for portal 2.

34:50 "The turrets really fascinate me" "I'm different!" AMAZING TIMING

One of my fav Game-dey Quotes comes from the Portal 2 Dev-Commentary: "Through playtesting, we found that smooth Jazz is funny to all Ages, Genders and Cultures". Really enjoying your Playthrough, and how invested you are with the Lore. I would encourage you to explore as much as you can, because similar to the first game, you get a lot more info about the Apature facility by doing so. Also Fun Fact: G.L.A.D.O.S. stands for "Genetic Lifeform and Disk Operating System"

I honestly think Portal 2 is Valve's finest work ever. Everything from the art direction, to sound design, and level work, it's just the peak of everything they've learned from all the games they made before. I'm so excited to follow you on this journey, aaaaaaaaaaa

I think a testiment to the quality of portal's design, is the fact that the majority of the questions he had in the video before this moment, we answered by literally 3 words : "Oh.. it's you.

You may recall from the slideshow in Portal 1, a slide listing a prototype fuel line de-icing system with the name Genetic Lifeform and Disk Operating System.

"Just remember what I said but in slow motion" Kills me every time XD She is actually saying something if you slow her words down too

Its going to be a ride. Portal 2 is often cited as one of the best games of all time and for a good reason. Things look a bit diffrent this time around mainly cause portal 1 was very low budget game made by basically bunch of students. Portal 2 is the "real" game so it got massive upgrade in design.

Highly recommend you read the online Portal comic “Lab Ratt” it basically connects Portal 1 and 2 and introduces an interesting character. It also explains how your character ends up in the position she’s in currently.

Hot take? This is Valve's greatest game. The dialogue somehow just gets even funnier every time I play it. A complete masterpiece of dialogue, storytelling, lore, art direction, music, sound design, and game/level/puzzle design.

I always feel that Portal 2 is 10 times the game Portal is. To me there are 4 distinct sections that are each equivalent to the content in the original Portal, then you have the sheer amount of story content over and above the amount you got in Portal, and then you have the added game mechanics (which I will not mention here for fear of spoiling things). It's a much larger experience.

The humour in these games is just... *chef's kiss*

One of my favorite things about Portal 2 is that Jonathan Coulton, who composed "Still Alive", the fun jingle at the end of Portal 1, was brought into be a part of the musical direction of Portal 2. So a lot of the musical cues you hear through the game, like the faith plates or the laser fields, are little things that Coulton composed to help the player navigate the game. It helps that Coulton is one of my favorite artists, so the fact that Valve enjoyed his work so much that they brought him on to be a part of the larger music composition is also fantastic.

It's finally here!!!! I love the fact that you're letting all the dialogues go on. They're just insanely good.

Such a fantastic game, and things are just warming up! It only gets better from here on, and I'm super excited to see your reactions to another one of the Valve Masterpieces that captivated a generation of gamers! Have fun, and get those brain juices flowin'!

I love when watching someone do a puzzle wrong laughing at how they're doing it that way only for them to find a new way you didn't know about. On that last room I always shot a portal out the little hole while up inside the room, to get a way to the cube. You're the 2nd I've seen use the cube as a step to shoot in thru that hole, but that other person only used the portals to aim the laser, and the cube was only means to get the right shot.

26:50 I mean, it is clear. White, light surfaces can have portals on then. Anything else, especially dark square surfaces can't. You shouldn't need the reticle to tell you what you can and can't place on, tbh. On another note, excited for this playthrough!

I would also say that this is the funniest, wittiest, cleverest game I've ever played. There are times throughout this when I literally laughed out loud.

He’s the only person I’ve seen not jump when dropping into a portal from a height 30:12 he just walks off, through portal one two and all the portal 2 mods 😭

1:01:50 If you listen carefully, you can hear the companion cube singing to you. The track that plays in this chamber is called "Love As A Construct" and the "singing" part can only be heard near the cube. It's a great relaxing, calming song to listen to ngl.

Before you played this, I was figuring you’d recognize Stephen merchants voice! Also I’m glad you recognized the difference in quality from half-life 2/portal to left 4 dead and portal 2. Valve did have that prop quality jump for whatever reason and it’s really recognizable to spot half life 2’s universe compared to their later games. I mean this in the prop quality because of course all game developers grow and make better things.

One of the developer commentary balloons is about how they did an expressive robot with no mouth etc., so it was nice hearing you pick up on that.

53:33 You missed it, there's a hidden room that you could explore.

I absolutely love his reaction to Wheatley being a robot and not a person. Your reactions to these games are exactly why I watch your stuff. You are so aware of everything going on and you actually pay attention to the story. It really sets you apart and we love it.

Wasn't expecting this one so soon, thanks Mapo!

The reticle now shows what portals you have open. If the Blue one is filled, for instance, it means you have an open Blue Portal. There is another way to tell what surfaces you can and can't shoot, however.

You are truly the gift that keeps on giving

So hyped for this! I'm so happy you're playing Portal 2 and getting to experience it! It's hands down my favorite game of all time. I hope you enjoy it!

Cannot wait for you to see more of this. Portal 2 is by far my all time favourite game and you don't see many blind playthroughs of it anymore!

Did you know, that Portal 2 is the most upvoted game on Steam of all time.

Between this series, your Half-Life videos, and your KotOR videos your becoming my favorite KZfaqr.

Portal is one of my favorite series, and I'm glad you're playing it. You got her name right, it's usually pronounced all together as GLaDOS, not as GLaD-OS. Hopefully you get to play Half Life: Alyx later if you ever get a VR set-up to keep up with the story!

"The crosshairs are a bit of a downgrade" Dude, they literally just spent the whole first game teaching you that speedy thing goes in, speedy thing comes out, and that portals go on white surfaces, not on black.

The companion cube has a heart on it's faces. And possibly has a living creature inside... Ergo the weighted bit.

Oh I'm so excited for this! Portal 2 is in the list of some of my top gaming experiences of all time! The more the story unfolds, the more I was intrigued and loved it!

Man, for some reason, this game is perfect for you. Always love the way you appreciate the world and think about things. Cant wait to watch the rest!! Masterpiece of a game, and probably my favourite dialogue ever, haha.

your attention to detail is great. I've played through this campaign at least 5 times and you're picking up on things I'd never noticed. You've earned yourself a sub friend

"Oh look. An actual computer." I know an IBM home Personal Systems 2 unit when I see one

Great first episode, Mapo. Looking forward to the rest of this series! It's really entertaining to watch these games played blind, to see what lands and what doesn't, whether that's gameplay hints, story and jokes, etc. Just shows we all experience games differently and developers do a hell of a job making sure we all come away having enjoyed ourselves!

These videos are so great! Looking forward to every single blind valve playthrough! Thanks!

This game is brilliant in so many ways! Dialogue, humor, environmental storytelling, music and sound, and satisfying challenges! It really keeps you engaged the whole way through. Super fun to see you enjoying it so much!

So, I am experiencing this game for the first time, through your videos, as I did with the first Portal game. The first game had me smiling every now and then, but this one has me laughing every few minutes. Man, I love the writing in this one. That whole intro with Wheatley had me going for a good while. I can hardly wait to see more of him, and GLaDOS herself also seems more fun this time around, at least to me. Keep up the good work, and thank you so much for taking us along on this amazing journey.

The music, writing, atmosphere, and everything about this game is just absolutely amazing. You’re gonna love it all so much

Very good playthrough. Love your attention to detail and the way you actually pause when you want to talk to not talk over the dialogue.

I absolutely love how you're enjoying the series so far!

This is so pleasant to watch, you are a lot quicker than other blind playthroughs I have seen.

That was awesome, i watched all of your half life 2 series and portal 1. And now this! I cannot wait for part 2 :D

This is one of my favorite games to watch other people play. I've replayed it so much, it's fun to live vicariously through other players who get to discover and figure things out. You're one of few players I've seen explore this much. It makes it easy to root for you, and I love the relaxed environment. Excited to watch Portal 2 and then see what else you have going on your channel.

Don't know why I started watching your channel. But I can't stop! Love your energy and commentary into these playthroughs

Yess! Discovered your channel today and immediately started getting hyped for this!

11 years of playing this game and for some reason I just NOW understood her "reanimating the dead" joke. I feel like an idiot.

man i love watching these. super excited to watch you play my favorite game!

Thanks for not having us wait. Already waiting for the next episode

Hey man, just wanna say that I found you super recently when you started HL2, and since then I've watched a ton of your Mass Effect and Souls stuff, and eagerly look forward to the rest of your Portal 2 playthrough as yet another person who loves this game. Keep up the good work!

Wheatly is so well animated because he was animated by Karen Prell, a former Pixar animator and Muppets puppeteer. She also animated the Vortigaunts in Half-Life: Alyx.

You are in for such a treat...I love portal 2. It is my favorite game of all time

By the time I got around to trying Portal, p2 was in late development so just like you I just did them back to back. Really helped my playthrough of 2. Thanks for getting me to reinstall these games, forgot how fun they are.

i am so ready and happy to see you play this

I already love this playthrough

I simply love how he did the test chamber at 1:07:00 backwards for whatever reason, as if it made any difference from which side you make the portals. That's what the hole in the glass was for

Oh yeah, I'm so excited for this!! One of the major things that I love this game are the environments as well as the humor and puzzles. The best is yet to come. The music is amazing too, which is why I bought the soundtrack.

Yooooo. Let's gooooooooo This journey has been great so far and I'm always looking forward to the next part

I love how most of the soundtrack is very muted and in the background but the different mechanics (like the lasers hitting their target or being catapulted by the plates) all have their own musical soundeffect and depending on what your are doing in a level the music changes dynamically. Very smart and makes it so the music doesn't feel to stale.

I stumbled onto this video today and I love it. Portal 2 is such an incredible game and improvement on the first. Easily one of my fav all time games. The dialogue is exceptionally funny, and you can easily stand around for 5 minutes at any point just listening to how much Wheatley has to say.

I Love this playthru and commentary! Keep it up.

Correction: Valve WAS capable of making a great sequel. Portal 2 was the last real game they actually made, and that was over a decade ago. I'm pretty sure the team that made these games has split up and moved on to other things by now.

This game was so good, and watching you run through blind is just reminding me how good it actually is. After playing through a few times, yea the jokes are still funny, and even the puzzles are interesting, but the wonder of the plot line unfolding is gone. Watching this is bringing back some of that and I'm really enjoying it :D

I’m late to find this series but two things about you that I love: First is your sense of humor. Second is that you seem to genuinely care about both the lore and the funny dialogue.

Just found out about your channel through your first Portal playthrough. Definitely hooked now! Subscribed, and gonna go through the rest of your content! Keep up the good work

Ah yess, Portal 2 is one of my favourites. The humor in these games is amazing.

Loving these playthroughs as usual, and this is out of left field, but I would love to watch you go through the first 3 Thief games. Your playthrough style would fit with them perfectly.

Yes, I needed this!

Man it is such a blast watching you play this game. I love everything about that game, and I really appreciate your experience of it. How do I say this without it being weird...I like your mind, Mapo!

So happy to see you play this... one of my favourites. Can I suggest the Witness also, another excellent puzzle game.

Portal is one of those games which really makes an impact on you, and Portal 2 really delivered for fans of the first game, fantastic sequel.

While never explicitly stated in-game, a developer commentary has stated Chell was in suspension for around 50,000 years... The Combine was around during Portal 1, by this point they're almost certainly LONG gone lol

25:06 here we go, I've been studying physics all my life for this one moment, let's go, so that's the heisenberg uncertainity principle, and below that, that's the lorentz factor, and then below that, that's the time-independent schrodinger equation, and above the "unreason" it's the time-dependent schrodinger equation, and then there's the schrodinger equation written again, a third time. And in the bottom right those are the maxwell's equations (I would call them maxwell-heaviside equations because oliver heaviside turned maxwell's original 20 or something equations into those 4 sleek looking equations using vector calculus notation)

YUSS! I replayed Portal 2 last night just so I could have a fresh mindset of what you would be experiencing lol GREATEST sequel ever. lol

“Valve really knows how to do a sequel” Well, as long as it’s only one. 😏

I love the way you play games my dude. New subscriber for you.

Love to see you play my favorite game.

FINALLY, you're gonna have a blast!
