Bah gawd, for YEARS I've wondered about that area in 12:19! This was a cool video! Learned some neat things today.

Well that explains why the Egg Carrier started to fall. Sonic caused it when he was on the ship's wing in the Sky Deck and damaged the wing. That's a nice attention to detail there.

Wow SA1's level design actually was kinda ingenious when you stop to examine it.

So that's why there's a giant freaking golden statue of Sonic... Didn't know he had such a huge ego to do that.

They really payed attention to detail, I'm amazed!

I would've added the biggest secret of them all in Final Egg, that there's actually two huge rooms where you just fall for a while, the secret one has tons of rings instead of a bottomless pit and you come out from it via a different tunnel (I first found out about it by running through this exit in reverse). There's also a room with two holes in the ceiling that have a secret corridor, only Tails can get there using a second controller. Sadly they didn't put any secret items in there.

IDLE BOSS VOICE LINES? IVE BEEN PLAYING THIS GAME MY WHOLE LIFE . DAMN. subbed

I'm surprised that there were things in this video that I didn't know about. Just goes to show that there's always something new to learn, no matter how much you know about one of your favorite videogames

I only discovered this a couple hours ago, and it may only be in one of the 20+ mods I currently have active, but at the very start of Amy and Big's Hot Shelter, there's a corridor with 7 statues on wooden display pillars, but an 8th pillar is missing it's statue. In Amy's version, there's a Kiki on the pillar, but once you destroy it, you can actually jump onto the pillar yourself and Amy will perform this weird balancing animation I've never seen before, and you have to try to keep her steady using the control stick. It doesn't seem to have a purpose as a mechanic, and is probably just an easter egg. I thought it might be a stealth mechanic, a way to blend in with the surroundings to hide from Zero, but I tried to lure it into the corridor and it kept de-spawning, so Zero must have some sort of personalized kill plane right at the entrance to the hall.

I always thought the sky deck took place beneath the egg carrier so seeing all these details i never knew happened like the wing breaking off and the pre rendered cutscene is kinda really amazing

I new knew the Sonic Statue was built by sonic with 5000 rings... Makes you feel bad for wrecking it.

I really got the impression from the design of Emerald Coast and Windy Valley, that they intended to have a lot more secrets and shortcuts in the levels, but didn't have time to add as many as they'd have liked

That last one is why adventure 1 is my favorite sonic game, I'm not knocking the others but I much prefer having a stage that has hidden goodies strewn about compared to just blasting down a on rails path, hell, I didn't even know about 80% of the stuff in this video and I've played SA1 for years, the only things I knew was big's hot shelter area(because unlike most "gamers" I don't automatically throw a fit and storm off when a game presents something different) and the idle talk, granted, I did not know about the boss idle talk. Thanks for showing me new things about an amazing game.

This is *really* interesting! From all my years of playing this game, I didn't even know half these facts... It actually makes me feel kind of stupid tbh :P

fuck yes I love this video and this channel. I thought I was an expert at this game, but damn this was amazing. The bit about the sky deck location and that tying into the FMV was particularly great

Here's some more secrets in the last story! There are hidden recaps you have to trigger them by accessing one of sonics levels and competing a stage this will force the game to save there are two that you can access without hacking the first when you first boot it up, and after Tikal's vision you can also do this by holding off on the light speed upgrade however I don't recommend that method as I've heard reports that it can permanently lock you out of completing the story

I don't know if you forgot or not, but you didn't mention in Sky Deck's Act 2, you can find Jump Panels, where you can jump through the destroyed cannon. Still awesome video through!

I’m extremelyproud to say I knew like... three of these.

4:44 "Old man offering movement assistance for heavy robot. Robot allows." "Old man is clearly strong, as he is holding him only be shoulders" "Away we go, old man."

OH MY GOD I've played this game for 16 years and spent countless hours exploring both adventure fields and action stages (except sky deck because I always wanna leave that place asap), and I'm surprised I've never seen the gamma elevator, the egg carrier lights turning off, the sonic statue's feet being there after 200 rings deposited, the "The Man 3" poster and the city hall clock moving! The only secrets I knew were the extra rooms in Big's Hot Shelter (I'm not proud of that) and the idle lines for adventure fields. Something I'll always love about this game is the attention to detail. This game is full of personality because of that and it shows how much effort and care the development team put on it to try to make it a new experience (everybody must remember it's an early 3D game, so glitches, bad camera and bad english voice acting are to be expected). I remember being blown away by seeing stuff like the showers in Casinopolis, the pool and game rooms in egg carrier (as well as the robot maids), the men's and women's bathrooms in hot shelter, the emblems hidden in random locations like the grass in city hall, and so on. And I just recently found out you can walk up those "inclined-plane" buildings near the beginning of Speed Highway as Sonic! There are even extra lives there, and I always thought all those background buildings were just background and Sonic would slip and fall those steep surfaces! tl;dr: I love this game.

A couple Idle Talks in bosses I've gotten before include: Egg Viper: "You've had your fun! Now it's my turn!" Egg Walker: "I know I can do it all by myself!"

That elevator for Gamma is a nice little touch. They wanted to teach the player the hover mechanic; the platform you're supposed to land on even has a targeting reticle printed on it.

I heard that Sonic Adventure kept the locations of Sonic 3 stages as continuity. Ice Cap and Red Mountain (Lava Reef Zone) are close together, Red Mountain (LRZ) is also close to the Master Emerald. Sand Hill (The one with Tails) could also be Sandopolis. I don't knoq if there's more of these but you could do a video on this or look for more similarities.

I see Big's Hot Shelter was more than just find the switch and catch froggy, Interesting.

you can use the z button (with mods) to make the idle talk, that will make more easy hear the idle talk when you're fighting a boss

There are so many details in these levels that you won't see if you aren't looking around. Like the little crew bubbles on the leading edge of the Wing in Sky Deck part 2, each with a little shield box in front of it. Then there's the absolute laundry list of hidden nooks and crannies in Final Egg. I wish SA2 had this much detail!

You deserve WAYYYYY more subscribers.

And I thought I knew almost everything about this game, great video! :D

Great video! The work you've put in and shown on this channel is incredible. The attention to detail in this game was always very impressive in my eyes, especially for a near-launch game from 1998. These little touches are just another great feature of a game that seems to never get the credit it deserves.

Being able to jump on Burger Man's head was used as a way to get Amy into Casinopolis in the Japanese version of the game.

And that's why its called sonic adventure. The game expects you to look around and find stuff.

That elevator was a secret? I thought that was the way you were supposed to go! ;_;

I always like to do the secret area in Big's Hot Shelter, even though it actually makes fishing in the main room harder. At least you get some rings and Chao animals out of it.

I miss Sega of Japan making the games....Rip Sonic 1991-2009

There is another secret, the showers inside of casinopolis trigger a animation as sonic. I recall being able to trigger the sinks in some way too, but that was the dreamcast version

Heads up, the echidna tribe pattern in the second part of Lost World are actually edited versions of Knuckles’ head from the cover art of Sonic Jam.

So wait, the area at 6:40 was a secret all along? I was just bored of failing to catch Froggy, so I explored. Man...I am GOOD at vidya gams

Been playing SADX my whole life, and beat the game, I only knew about Big's Hot Shelter path (recently discovered), the idle talk and the rings shaped like Sonic's face (not gonna lie--I HAD to Google that, I spent years trying to find that spot with no luck.) Some awesome stuff in this game! I wish the modern games could've been made with this much love.

OMG FInally ! Now I know what was those ladders in Final Egg leading to!

Apparently, in the steam rerelease, my brother with a switch controller managed to find a button that automatically triggers the idle talk. I think it was one of the shoulder buttons. That should make it a lot easier to hear the boss chatter!

I always liked this game, but I'm starting to have more appreciation for it. With all its success and flaws, you can tell SEGA put a lot of effort into it.

If you glitch into Hedgehog Hammer through trial mode as anyone other than Amy and you turn the camera up, the outer shell of the light above you is gone and you can see what's underneath. Surprise surprise! It's a face you know well, but not one you'd expect to see here! EDIT: I know this for sure works on the GCN and Steam version of SADX, not sure if its in DC original.

I've been playing this game for 15+ years now, and never knew about any of this stuff. Great video!

That's really impressive. I had no idea about most of these. But yeah I had figured out the gold Sonic Statue thing a while back. Still glad you mentioned it though. But about the unused assets. I'm pretty sure this game was maybe 70% complete at launch anyway. I kind of wish Sonic Team would go back and make remake the game as it was planned and not just what they had to put out to meet the 09/09/99 launch date.

So, uh, how do you only have 145 subscribers? (definitely deserves more subscribers)

Thats why sonic adventure is one of the best games of sonic

Seeing that title screen at the beginning of the video makes me want a SADX PC mod of it with the SADX branding.

Wow; all of these are really neat! Fun fact, though; did anyone else remember an old LPer called "Darkersupersonic"? (Not to be confused with the speedrunner, 'Darkspinessonic') He did a playthrough of Adventure DX circa. 2009, and actually showed that slowly-moving platform at the end of Final Egg; he didn't show any of the other stuff in this video, though. God I do miss his videos; they were very good fun :)

11:05 WHEN WILL YOU EVER LEARN. THAT YOUR ACTIONS HAVE CONSEQUENCES.

Your a Real Pro for finding these secrets! I've been playing this game for years and I didn't know some of these secrets!

Thank you for showing cool new things about one of my all time favourite games. All these years and I had no idea about things such as the idle boss lines, the hidden extra lives path in egg Carrier, etc. :)

i love he inst remix.of it doesnt matter

I actually found out about the 4 lives area in Final Egg on accident only about a year ago. I was trying to attack the enemies and they charged me while I was midair pushing me up and clipping through the platform. The camera went screwy so I didn't know where I was, and when the camera panned correctly I still didn't know where I was. Got my four lives, went down, and realized that I found a secret area through Sonic Adventure shenanigans. I love this silly game.

At the beginning of Hot Shelter, there are a bunch of pedestals with some small statues on them. One of the pedestals has a kiki badnik on it, and when you destroy it, you can jump on it. When you're playing as Amy, she loses her balance and falls off. Not sure if this is a secret, but it's a funny thing I noticed when I was playing the game.

I've been playing this game for a decade and I didn't know about some of these

What a great video! I honestly didn't know about alot of these things (if not all of them), so it's really fun to see someone going though the Sonic games much like that guy going though the Mario 64 games and learning new stuff, many, many years later. You're doing great work! :D

this music.... i wish sonic was like this today....

wow all this time i’ve been trying to go fast i never got the chance to look around the areas. Thanks for enlightening me.

SA is my childhood game on PS3 and still love it😍 Thanks for showing this :) BUT THE FACT THAT AFTER MORE THAN 6 YEARS OF PLAYING IT I LEARNED HOW TO CATCH FROGGY WITH BIG AND DON'T TELL ME HOW BUT YOUNGER WITHOUT EVEN KNOWING HOW I DID I CATCHED FROGGY YOU HAD TO MOVE THE L JOYSTICK 😭😭😭 Btw the Casino move is totally normal, sometimes the view does that It's like Cream being an easter-egg in the game, on levels you can see her The 2 times where i saw her is: At the beach, at a light, when i played Big The Cat, the day, in front of the Hall train place And at the Casino while trying to remember how to use a key stone lmao The fact those gameplays you show are form the Dreamcast game, so the original game and with the sketches, or whatever I have the PS3 version, and since before remakes were real remakes, it looks super alike, i nearly couldn't recognize it would be the Dreamcast version without looking at the 3D model of Sonic That is when you don't pay attention to the normal gameplay, butonly at the 3D model Because if you pay attention, you see the 3D's not the same and textures too For example, at 13:35 , the black balls with the needles or i don't know, well, on the PS4 version, it's darker, with better shading, and the needles too

Came here thanks to SomecallmeJohnny, and I found this really interesting, for someone who's played Adventure over and over. In fact, I think I'll sub.

Wow, nice facts, some of them didn't know at all.. I was especially amazed by 5000 rings statue you can build, so much time of playing this game and didn't even notice at least built Sonic's shoes at 200. Nice!

This was a really cool video.

Those details they included in the Egg Carrier prerender blew my mind!

It's really too bad this video doesn't have more views! It's very nicely made and informative. The presentation is wonderful :)

Sick vid :) I'm surprised by how much stuff I hadn't noticed after all these years

11:05 THAT YOUR ACTIONS HAVE CONSEQUENCES

I just discovered this Sky Deck shit myself today and I went to look up to see if anyone else had figured it out, turns out you even noticed they show it in the pre rendered cutscene too! x)

wonder why these rooms in big's version of hot shelter are so oddly hidden. maybe sega wanted to give some sort of reward for the curious people?

Maybe the idle sounds for perfect Chaos imply that there was originally more to the boss, after all the final boss of the game does seem a bit lackluster to me. I was super surprised to learn about all the hidden features in Skydeck, it really made me appreciate this stage a lot more being that it gave me mad anxiety as a kid, great video SPEEPS :)

I only knew about the secret on the upgrade room, Hot Shelter with Big, and Final Egg's room with 4 lives, everything else was new to me, so cool!

There's also the whole Egg Walker thing where, if you press Y, it starts moving without the AI's input.

Might just be the casinopolis music you've got in the background, but that "The Man 3" poster gives me a James Bond vibe...

there’s just something so fucking funny about “The Man 3”

I thought the Camera went up when you were at the entrance to the casino, to show you where the switch to open it is for Tails. As for the Sonic Statue, I think the collision data remains for Knuckles after he destroys it or there's collision data for it when you moon jump up there as Sonic.

I actually learned of that second Final Egg secret area from a strategy guide back in the day. Kinda neat.

Really interesting!! I am looking forward to watching that clock next time I play!! Personally I would have also mentioned the commercials for NiGHTS into Dreams above the Golden Sonic Statue but hey :P

I knew only the Hot Shelter's plug secret and that characters spoke suring idle animation. (except for the bosses of course) The details about Sky Deck were cool!

9:17 i think this was originally used to show you how to get into the casino, but the trigger is too far inside.

My god so many things i never knew about all these years.. Amazing analysis video!~ :D

this was awesome. only one I did was waiting for the platform at final egg. keep up the good work

I palyed DX so much and I can say one more thing. You can achive twinkle park card for every character after you clear half or maybe more missions. This card just left in corner near to speed highway stage entrance. Now everyone can ride on this funny cars.

Never see anyone talking about the area under the conveyor belt room in final egg act 1. It's probably not as good as other fairly hidden areas but strange that no one really mentions it

All these details and yet there is one that was sadly not mentioned, the most overlooked detail of this game: Amy Rose is pigeon-toed.

Huh, I never knew the Twinkle Circuit theme sampled "It Doesn't Matter".

i cant believe sonic's gambling addiction is canon.

Holy crap, and here I was thinking the casino's giant sonic statue was a knuckles-only thing.

Fighting Chaos 0 was so easy and fun 😀

Very Nice and Entertaining Video Enjoyed it a lot Keep Up the Good Work :) ;)

I knew about the back 3/4 of Big's hot shelter, it's still there in SADX. I always thought it was weird that there was nothing there.

There's an unused Casinopoilis area I found

5:31 My Biggest nightmare.. 4 HOURS CONTINUOUS PLAYING JUST FOR FINDING A 50gr HEAVIER FISH!!!

and another one is by seein this vid the cutscene theme that sounds when tails is about to crash contains a lil part of sonic credits theme AKA It doesnt matter

I think you forgot the secret area in Dilapidated way in Casinopolis. well it's not actually secret, but there's no reason to go to it, other than some extra items.

Man, the Egg Carrier is WAY bigger than what the overworld portrays it as.

looks like ive got a new channel to vibe to.

Never knew the racing minigame from twinkle circuit was really Sonic's theme song

"The Man 3" is supposed to be Ipman 3, at least I think.

The man 3 looks like a reference to Dr. Curien from the House of The Dead. But i could be way off.

for the limit of tech sega had they made this very great for the current time it was in development

The main deck in the distance thing is something I never noticed at all. I'm fucking shook.
