imagine gaslighting a 90's kid by swapping his sonic 2 cartridge with this, him finding a secret zone, then swapping his cartridge back to regular sonic 2 when he tries to show it to his friends

I love how someone saw the secret entrance to Hidden Palace Zone and was like "What if all the other scrapped Zones did that?".

The idea of bottomless pits leading to alternate routes instead of death gives me big Rondo of Blood vibes, and I’m all for that.

I just love how the scrapped zones (even Genocide City) had this organic flow and felt like they were always there hidden until sonic ventured off the path and discovered a whole new hidden world.

0:43 bro really going so fast he phasing through springs

It's been too long since I've seen a creative take on a ROM hack. I hope they update this with improved art. This may become my definitive way of playing Sonic 2 if they build upon it.

I just love how the scrapped zones (even Genocide City) had this organic flow and felt like they were always there hidden until sonic ventured off the path and discovered a whole new hidden world. Specially the fact with some zones like Sky Chase or Metropolis Act 2 where you had 3 whole acts of Metropolis, here instead if you fall into the secret Cyber City zone you skip Metropolis Act 3 entirely and in sky chase if you fall into Snowy Winter zone not only you get a whole new zone to play with but the second part of Cyber City which leads to a totally different way of getting into the Death Egg, love how tails gets behind to operate the computer that allows sonic to being teleported into the Death Egg making more sense why Tails gets behind in the first place. The only thing i can nitpick about it is the lack of level transitions make them feel very disconnected from the regular main zones, the main zones were already very disconnected from each other without proper transition, but its just a nitpick because it fits with how Sonic 2 was made and because level transitions werent a thing until Sonic 3, but if you the creator of this hack ever read this it could be cool to have level transitions that makes the already nice flow the secret zones have even nicer if you ever want to revisit this and add something up to make it even cooler that is.

Who else prefers the look of the beta version of Casino Night Zone? It just looks much more vibrant & inviting to me.

Wow, this hack is pretty accurate with the music and zone decision

When most video games have secret entrances to hidden levels, the entrances are usually locatable through the player's own observational skill, not by jumping down a random bottomless pit. Why would you take an obstacle which is usually made to punish incompetent platforming, and now make it a reward? I'll say this though, I like the Oil Ocean --> Sand Shower secret. It's clever how at 17:11 the pathway right before you take that green elevator has a small glimpse of the bottom of the secret platform. It was a smart way of hinting to the player that a platform was floating there, without straight up showing us the platform in full.

Something I like about this is the fact that, despite the new zones, it's still Sonic 2. You can play through the entire base game, and not go out of your way to discover any secrets, and it would still work!

i like the hidden paths, their entrances fit really well within the level

The idea of ​​expanding the secret entrance of Hidden Palace (Of the 2013 version) with the other deleted zones is quite epic

imagine being a time traveler and going to the year 1992 and then showing everybody this alternate version.

1:37 rock world zone ( was supposed to be a past version of sand shower zone and sonic 2 was supposed to have a time traveling feature and was probably scrapped to be in sonic cd it is not in any old builds of the game) 10:29 wood zone (Simon Wai build) 14:32 hidden palace zone (2013 iOS remake but a bit different) 17:24 sand shower zone (was supposed to be named dust hill zone I think also only is in Simon Wai build and nick arcade also was in sonic cd as desert dazzled and in sonic mania as Mirage saloon zone) 25:38 cyber city (was changed because of a word KZfaq wouldn’t like also could be a cybershell reference cyber city was a mechanical based zone and was scrapped for act 3 of Metropolis zone it was also reused for the Machine in sonic cd) 26:57 snowy winter zone (was supposed to transition from sand shower zone and was based of of sand shower zone) 27:37 cyber city zone (again) 28:57 death egg zone (not a secret level but is way different from the actual death egg also was supposed to be called the last battle in space and was remade into sky chase was in the Simon Wai build) There are also these unused levels : Ocean Wind Zone (was meant to be the second stage in the game after Emerald Hill Zone and would've been a coastal area with piers) Tropical Plant/Tropical Sun Zone (a rather unknown stage with only concept art available) Blue Lake/Blue Ocean Zone (also rather unknown of a level and only has concept art was also reused for wing fortress) Madness Mountain Zone (ANOTHER rather unknown level and only has concept art available also possibly a early version of mystic cave) Emerald Isle Zone (a scrapped stage similiar to Aquatic Ruin Zone It is unknown if this was an early name for the level) Olympus Zone (one of the most unknown stages and only having proof of its existence is an early map of sonic 2 Hirokazu Yasuhara identified it as "The Shrine" given that his timeline notes a "Hidden Shrine" it’s possible this could be a earlier version of hidden palace zone) This took a long time so please like. 😄 Edit: 14:32 @kalpana gurung reminded me in the reply’s that hidden palace zone was actually not a modified version of the 2013 Christian Whitehead remake it was the proto palace secret where in the rerelease if in the sound test you played the sounds 3 3 3 B 10 10 10 4 and selected the hidden palace zone then it would load you into the original hidden palace zone or as it’s called here proto palace zone where the layout is the some as the original there is even a tails monitor and when you step on the otherwise breakable emerald you teleport back and I find it interesting because lots of people believe this was originally how you get super sonic and a similar green emerald was used in sonic 3& knuckles which also gave thing like meca sonic a super form so is this a coincidence? I don’t know but it’s pretty interesting! Also in 25:38 @certified gamer also reminded me in the reply’s that this wasn’t a cybershell reference it’s was changed because the Japanese developers where trying to make a cool name for a level and when they translated it it said well I’ll just say cyber city. And also at 7:24 prismatic prongle reminded me about the old casino night zone it’s not really scraped they just changed the colors probably because there was way too much color in the level and also changed the layout I mean look at all that pink.

The hill top to wood zone makes so much sense. Hill top is basically a mountain so falling into a forest below it makes so much sense

They should have put these zones in Sonic Origins

1:34 rock world zone 7:19 proto casino night zone 10:27 wood zone 14:29 hidden palace zone 17:20 sand shower zone 25:35 cyber city zone 26:50 snowy winter zone 27:34 cyber city zone 2.0 28:34 death egg zone 2.0

I love how you can ditch wing fortress of you spindash off the plane in wing fortress, clear snowy winter and cyber city 2, and you just get sent to death egg without beating wing fortress.

Aaaah, very clever reference to Mario 2: The Lost Levels. very clever 👏 👌

Nice idea to have beta casino night accessible through regular casino night, it’s like a second floor.

Wouldve been really cool for cyber zone to be the Act 3 Metropolis zone as it was intended to be

Love the idea - basically expanded upon Sonic 2 Remaster's method of getting to Hidden Palace

They ACTUALLY called it Sand Shower. Props to the creators of this hack.

The nice version of S2, idk what to say

... This guy has played this game since 1946 y'all man has some serious memory and luck

New transitions for secret zones, huh? Sweet!

This hack is awesome! the idea of finding an hidden level that is an alternate route in the game it's so cool to me

reminds me of the Sonic The Hedgehog 2 "Complete" Edition, which wedged in a bunch of "cut" zones. It was never actually completed - Wood Zone was missing a bunch of level geometry and Genocide City just reused Casino Night's layout - but the "restored" assets were nice at least.

poor Doctor Ivo Robotnik, don't matter what hidden level there is Sonic always messes up his plans

I really love the idea, and some of it is very nicely done! However most of it is extremely half-baked. For example many of the extra levels are super short and or unfinished in quality, making them seem simply like bad early alpha levels instead of properly finished cut levels remade to feel legit part of the final game. Stuff like the Hidden Palace Zone here is a inferior version compared to the official Sonic 2 Remaster version... Not only does HPZ need the remaster boss back, but the other hidden levels could really use some new bosses too in order to help it to be more exciting. The levels are just disappointing currently in execution. Hopefully more work will be done to the hack later, because it is a decent start for real, but it could be far better.

It like the 2013 remake of Sonic 2, but expanded in more secret levels! Great job!

Fun fact about the original Cyber City, the graphics that we're going to be used in the zone got repurposed for Sonic spinball in the level the machine

How to make a secret zone: take any infamous part of a sonic zone ( like an unexpected pit ) and make it lead to a scrapped zone when you fall for it.

The transition from cyber city to death egg is really interesting

First time I'm seeing a hack with wood zone with a good level layout.

i love the detail where the tornado doesn’t have the rocket cause it didn’t get shot down

8:15 Perfect beat

I hope that this mod eventually makes its way to the 2013 remaster of the game

This is the best hack about the missing zones that I have seen.

I like the transition to the death egg

This is really clever.

This is actually pretty cool

Rock world looks like the past hill top I love how prototype casino night looks!

honestly would’ve like some unique bosses but i have to admit, this is a pretty cool rom hack

Good ol' proto palace.Its even finished!

We are so damn close too getting a sonic 2 that the team originally wanted too make. This might as well be called sonic 2 definitive edition

Great vid

22:40 Impossible

Hidden Palace zone looks so good

I was worried they might've not used the hidden palace zone song for it... phew!

Fun fact: did you know that Metropolis 3 is a scrap level of genocide city. Fun fact 2: colorful casino night is actually in the prototype

I hope alot of these zones get put back in at some point!

Cool sonic hack!

When you fell somewhere you werent supposed to fall, but you didnt regret that.

This hack makes Sonic 2 feel more open

1:35 a question about special areas I mean, emerald hill are above rock world? 7:21 In casino night I remember that there were many areas with different colors or aspects

Just saying for sonic mania 2 if it ever comes out I just wanna see these cut zones fully realized They did that originally with mirage saloon

Cyber city actually looks cool

Every single sonic extra zone hack no matter which game it is: hmmm ok imma borrow bosses from existing ones and call it a day.

Damn this is cool, i hope someone ports these to S2(2013)

Secret zones: Rock World Zone Old Casino Night Zone Wood Zone Hidden Palace Zone Sand Shower Zone Cyber City Zone 1 Snowy Winter Zone Cyber City Zone 2 Death Egg Zone

I played Sonic 2 a lot when I was younger and never even knew these secret stages existed. Which format release where they on? Also when you finished a secret zone did you return to the one you bypassed from or just proceeded to the next?

It's almost certain that the hack's creator saw Collision Chaos Radio's video about the prototype

Can you make this mod on console? I want this mod on my switch

fun fact: hidden Palace was called blue lake in sonic 2's concept art

I noticed that many of these extra levels have an appearance in sonic 3 or sonic and knuckles.

Secret Zones: Rock World Zone 1:35 Proto Casino Night Zone 7:19 Woods Zone 10:27 Hidden Palace Zone 14:30 Sand Shower Zone 17:21 Cyber City Zone 25:36 Snowy Winter Zone 26:56

25:37 HELL YEAH CASINO NIGHT ZONE 2P VERSION MUSIC!!

Cool

fun fact: aquatic ruins have a secret zone and in the secret zone you play as amy

1:34 :o

Hey, I saw that sometimes when Sonic jumps he completely turns into a blue ball. Why?

Wood zone and rock world are my favorite (EDIT) i like hidden palace too

They should've utilized some of the prototype music for the hidden zones.

Secret zones in: Emerald Hill, Casino Night, Hill Top, Mystic Cave, Oil Ocean, Metropolis, Sky Chase, Snowy Winter

Looks alright. Rock Zone looks pretty lame though.

To be honest, while the stages are cool and surprisingly accurate in some cases, I don’t like the way in which they were implemented. They feel incredibly arbitrary, and too short for something I had to jump down a random bottomless pit for, especially with the fact it isn’t consistent (Winter leading to Cyber for the boss fight, Dust Hill found by cannon,Death Egg being a full stage like in the concept regardless). While I get Hidden Palace had you do this in the taxman port, it was under a bridge where you could jump under because it was closed in front of a pit, meaning multiple players could reach it accidentally- plus, it’s called *hidden* palace for a reason. From a game design standpoint, some people could play the entire game without finding any of these if they didn’t have a guide or something. I also don’t expect the dev(s) of this mod to make it a grand experience like Sonic Delta, which had new bosses for most of these zones (even backporting the Taxman Port boss to Hidden Palace), but I’d rather it at least be more of a showcase rather than a scavenger hunt to find which random hole I have to jump down to access the thing I downloaded the mod for. The devs should least re-arrange the level order and include the new stages in it or make it so the game kicks you to Level Select immediately, or something.

will this work on my sega megadrive2? or is this on a different platform?

Emerald Hill act 1: S P E E D R U N !

Huh. Aquatic ruins theme kinda works for a desert setting.

This is just a normal sonic 2 playthrough if these zones werent scrapped

my guy taking clutches and no dmg, giga chad

Plot twist: Tropical Plant fades into reality

1:35 Rock World Is Taken Place At The Bottem of Emerald Hill. And Has The Hidden Palace 2P Music.

4:34 so that’s how you keep your one-ups

May I ask why rock world is not accessible through hill top? Because that rock world background certainly looks like the bottom of hill top zone.

This is what Sonic 2 8-it should've been. Not that 8-bit Sonic 2 wasn't good as it is, but it would've been cool if the sequel had some consistency with 8-bit Sonic 1, where we have stages from the 16-bit version, with some new ones sprinkled in to make the experience unique. Another cool idea is that if you played as Tails, when you reach Wing Fortress and the Tornado is shot down, Tails would be taken to Snowy Winter Zone, similar to Knuckles' route in Mirage Saloon in Sonic Mania, and have to fight a new final boss, like maybe a computer that controls the Death Egg, or a modified Silver Sonic.

I do like how in emerald hill in the normal game in that put you die but in this hack it takes you to rock world

Sonic: you know what? fuck it *unskies the chase*

Yeah kind of sad we don’t have new bosses for each zone

Wait this is really fucking cool

Fun Fact: 14:29 That Hidden palace zone entry exists in Android remaster

They had the option to let you skip metropolis zone and didn’t take it, sad. Otherwise great mod although the levels are a little short

Speedrun time!

if this was real sonic 2 would be the actual perfection of the mega drive

If the secret zones were in sonic origins.

Cool!

I dont like Snowy Winter Zone. It's a reskinned Sand Shower Zone with generic presents. Only thematically appropriate one time a year. Plus it's too easy of a level to be put at the end under Sky Chase Plus these don't seem to be put together with any challenge in mind. Nice aesthetically, but they kind of play themselves right? New Death Egg sequence is cool
