Undertale Yellow Launch Trailer 

The full OST is live on its own RU-vid channel (mind the spoilers!) www.youtube.com/@UndertaleYellowOfficial

The fact they followed the Toby tradition of having that one part of hotland in the trailer for literally no reason is truly great

A lot of fan games are either never completed or just forgotten entirely. However, you have managed to do what many fan game developers couldn't. And for that, I, as well as the rest of the Undertale fandom commend you. Congratulations on this incredible achievement! I already know I'm gonna enjoy this!

I will forever consider Undertale Yellow to be a canonical prequel to Undertale, that's how good this game is.

It's an honor to be here. Since playing the Demo, I have never forgotten this Fangame, and I want to thank everyone involved for not abandoning this wonderful idea. I hope your work can be rewarded 💯💛🤠

I love the commitment to making sure that every Undertale related trailer has that one jump maze in hotland shoved in somewhere.

i'm gonna tell my grandkids that this was red dead redemption

This is such a fun game so far! I remember playing the demo back in middle school, time flies 💛🤠

The animation in this trailer is stunning! 😍

1:02 I like how at this last part, it looks like Clover is about to fight that enemy, but no, that's how you spare them. By yelling. What a good game.

I love the sheer dedication behind this project. The animation really shows how much the community is willing to go far to for a game that impacted them so much.

After 7 years of hard work, creativity, and most importantly passion on creating a prequel that could possibly tie in ends to the original game. We now have officially reached that finish line I just want to say thank you for everyone who worked and was part of the project for finally getting it done Toby Fox will officially be proud of you.

0:43 Either Clover is tiny, or that apple is large as hell and Clover's gut is now completely destroyed.

Most Undertale fangames get cancelled after only around a year of being in development, either because the developers lose interest, the players lose interest, etc. I feel like you guys could really teach other indie devs a thing or two, since you've stayed so devoted to this project despite having taken several years to finish. Great job, guys!

Good time to enter the Undertale fandom. You guys are amazingly committed and that’s a feat in of itself. I wish there’s was a way to show support besides saying “thanks”. So, thank you for your work!

Every other soul: has cool abilities and lore Yellow soul: for his neutral special, he wields a *G U N*

Finished the Pacifist route like an hour ago…I can definitely see why this game took as long as it did. As someone who wants to become a game dev myself, this is legitimately inspiring. I almost don’t want to play the genocide route just because that ending was so perfect. This game is legitimately on par with undertale, and I commend everyone who worked on it. Genuinely, the best UT fangame I ever played.

0:54 As a vent enthusiast, I am very glad you kept this part of the trailer. Seriously though, this is an amazing achievement. After so many years of Undertale content, somehow a fangame that spans the full story has still seemed just out of reach every single time. But you guys did it, you made the ground and put your hearts and souls into this project. All I can say is, amazing job, to every single one of you.

Flowey went from "Howdy!" to "Howdy, patner!"

I am so thrilled for you all! Big big congrats on getting this game out in the first place and I can't wait to play it myself!

I love how Toby is not just open, but very accepting of fan projects. if he wanted, he could probably work with you guys to make the other colors too. Honestly, that would be really really cool.

Ok but can we talk about how *sweet* is clover hugging sweet corn?

This is, by far, the coolest, most faithful fanmade Undertale prequel I’ve ever played! Pretty much all the gameplay, jokes, story elements, and charms feel so akin to the original Undertale here! Although the story itself is non-canon, it feels like it could lead to the original events of the game. It was amazing to play through the game from Clover’s perspective. Thank you, Team Yellow and MasterSwordRemix, for all of your amazing efforts and being able to share this with us!

Love how you added the vent puzzle just because it was such a prominent feature of Undertale’s marketing. If Deltarune Chapter 3-4 are still a ways away from being released, then this is probably the perfect thing to satiate the lack-of-content fatigue. I hope everyone who worked on this is proud, because they should be! This is amazing, and I can’t wait for what this team has next in store!

Okay, so, now we have: • “Undertale” - September 15, 2015. • “Deltarune, Chapter 1: The Beginning” - October 31, 2018. • “Deltarune, Chapter 2: A Cyber’s World” - September 17, 2021. • “Undertale Yellow” - December 9, 2023. Damn, this franchise is getting bigger and bigger with every few years and i loved it so much 😎😍👍!

I played this on stream back in college, it was my favorite of the bunch. I applaud your perseverance through the project, I'm sure it wasn't easy. enjoy the fun that comes afterwards! you all deserve it. ^^

The release of Undertale Yellow is so important that it crashed the Gamejolt servers LOL

The way Clover gets hit in the gut with a giant apple is hilarious. Classic gag!

i played the demo all the way back in middle school and now i'm in college ready to immediately play the full game when it drops. so proud of the team for their dedication over the past 7 years, you've all truly made something special

Justice is one of my favourite souls, and this looks stunning! Glad to see that the Undertale fangame community is still going strong and making bangers.

I just realized tjat of all the fallen humans, I’ve *never* seen _anyone_ *ever* debate Clover. Like, I’ve seen more disagreements about *Frisk* than I’ve seen about Clover, and that’s saying something. Normally, there’s at least like 5-10 different competing ideas for each of the fallen humans that get cycled out every few months, but I have *never* seen *any* alternatives for the Yellow soul. Just goes to show ya that all it takes to make a great game is passion, inspiration, hopes, and dreams. You guys really hit it out of the park. That ending got me crying for hours (and also sent me into a deep depression lasting jsut shy of a month where I’d occassionally break into tears and sob over Clover’ death for 3-5 hours). You guys did a great job, and I hope someday soon I get so see Clover once more. Love yal! Yeehaw! 💛

I just finished it. You guys made me cry 😣It was worh the wait. Thank you all for not giving up on this. You and your team deserves all the money on the world. Thanks.

Amazing animation

10/10 would recommend to anyone who liked undertale. only problem is that I did a pacifist run on my first playthrough and now I'm too attached to the characters to do a genocide run or even reset

Man, this is great. I remember playing the demo, what, 5 years ago now? This is one of the only real, full, Undertale fan games to ever come to fruition, and I really respect that. This is truly amazing.

the amount of love and dedication this it put into is crazy

How can I enjoy this trailer there's no 3D toriel?

Game so fire it crashed Gamejolt on release.

Yes!!! Finally!!! I’m definitely going to be playing this! Almost can’t believe that this game finally came out

The most f***ed up part about this game... is that it's free.

Игра будет на русском? (

Just finished the game. You and your team did such a great job.

I think Undertale Yellow is the best thing to happen to the Undertale fandom. Both because the game itself is a masterpiece, and it drastically encouraged fan content that isn’t just “Sans Undertale does the edgy thing”. Thank you so much for creating this game.

Okay, I'm gonna be real. This might be one of the best, most faithful fan games I've ever played. It is an honest to goodness prequel with so many secrets to find, complete with routes that vary even more than the ones in OG Undertale. The charm is all there, the emotion is all there, the creativity is all there, everything - it feels completely authentic. The polish is so complete that Toby himself might as well have made it at times. On the same token, it brings so much new to the table, and it'd feel wrong to spoil even a crumb of it in this comment because it's all so good and it's all _free._ Props to everyone who worked on this project - as someone who was a freshman in highschool when it was announced and has been waiting since, it truly paid off and then some.

it is actually insane seeing this is finally coming out. def gonna be playing it as soon as it drops, congratulations on the release!!!

I just finished 2 of the game's routes. Honestly up there in quality with Undertale itself. I am blown away that such a faithful yet original fangame ended up being this good, and FREE?! Truly an amazing experience you guys crafted. Loved every moment with it and still have one route left to try!

After 7 years, it's finally here, can't wait to play this man!! Fun fact: b8bbles (the creator of undertale last breath the musical) today, is his birthday, congratulate him, and i'm telling you this bcuz he created the meme "Blocked once more"

Man, after playing the full on game this hits different in alot of cases. Most undertale fangames are either: Unfair, Stupidly short, An AU on a overused skeleton, has a dumb FNF mod on the main gsme or another AU, or just flat out canceled. This is just sad to look at Undertale nowadays (For me) as like most Indie games, They start off amazing but get too much controversy. Mainly from having a bad fanbase, the developer gets called out for doing (Inappropriate) stuff to others, or just gets to much content farms that it's just considered brainrot. Also other Undertale Fanmade stuff that created such as Animated series are usually good at first, but get bad such as Glitchtale and Megatale. However Undertale Yellow is different from all this. It's a full on game, A FULL ON GAME and not a stupid AU. This game took 7 years to make, 7 YEARS and the game didn't get discontinued or canceled (Like other content). The game perfected Undertale is many ways, from the animation to the art style. I can confidently say that this is the best fangame in the history of Undertale fangames, the characters are original, the music is original, the battles are balanced EVERYTHING IS ORIGINAL! And the the last line "For Desmond"... Etika would've love to see this fully finished, it's sad that He couldn't see it. RIP Desmond Daniel Amoftha. Thank you MasterSwordRemix and the team for never giving up on this game and congratulations on making a masterpiece that I will never forget.

i think gamejolt crashed idk tho

Y'all crashed gamejolt 💀

"undertale yellow isnt canon" ITS CANON TO ME

*the fact that after so long this fangame has been released fills you with DETERMI- uhh I mean JUSTICE* *HP fully restored*

7 long years 7 YEARS waiting since the demo released back in 2015-2016 and I couldn't be more happier with the wait. This fangame is one I have been checking on and I am glad I have. Most fangames I have watched and waited for have mostly been canceled, delayed, or not done. I am glad y'all was able to stick onto this project and fully complete it. Thank y'all for rewarding all of our patience.

Bro this game is The best fangame, saudations from brazil

game so good it killed gamejolt

This project was in development as far back as in 2016, when the UNDERTALE fandom was in its infancy. I haven't been following its development at all, and in a post-DELTARUNE Chapter One and Two world I thought the project was on hiatus, if not cancelled. Welp, guess I was wrong, because you guys pulled through and have finally unleashed your passion project onto the masses! It's surreal to see this fangame completed, and I'm definitely looking forward to playing it very soon. In the meantime, congratulations to everyone involved in the project for making your dreams come true!

So what is this game about Undertale yellow : GUN

Thank you for this masterpiece. Also the animation is very well done! 😊

Congrats on the release! This fandom is amazing and you guys worked so hard to keep it alive

As I watch this in a clover cosplay, I am happy Also: clover is such a cute little silly guy I love him He’s so sweet

Just played the whole thing, not surprising, but... TEM OUTTA TEM!!! PERFECT GAME!!! GIVE YOURSELF A PAT ON THE BACK AS YOU BASK IN YOUR NEW GLORRY!!! The humor was spot on, the music was worthy of the original, the graphics were _better_ than Undertale like a bonafied official sequel, it crafted a good story that had me hooked, characters that I'll remember, great battles, all around a HELL of an experience that kept me entertained for 12 hours with two 20-30 minute breaks for food! Be proud of yourself, because I am proud of _you!_

i've just played the game and i have to say, it made me feel something even undertale did not. while starts off as a cute world, very much inspired by ut, at some point it becomes a crazy adventure, filled with heartbreaking moments and a unique, captivating atmosphere. and the pacifist ending - it made me shed a tear. i'm absolutely in love with what you've done.

Is clover okay? That apple looked like it hurt…

Мы дождались господа! Благорим создателей за то что они проделали этот труд ради нас! Спасибо вам!

Wow the hype was so huge that Gamejolt imploded on itself.

I hope you can buy a full auto assult rifle and shoot sans insted of it taking 2 hours

Congratulations, you have crashed gamejolt.

0:14 i recognise this face from somewhere else

This technically means that normal undertale is just undertale red

This sparked a kid inside me. Playing the demo years ago hoping that one day it would be complete, and here we are.

We finally made it to the release! What a journey it's been, congratulations to everyone and their hard work on this game! I can't wait to play it!

How's it only been four months? Felt like the games been around as long as Undertale

creo que gamejolt ha petado

Words cannot describe the gratitude the fandom as a whole have for you guys at TeamYellow due to sticking and finishing a project, which is sonething most people were unable to, we salute you.

Clover: gosh that was a clo-*Apple falls on him* OOF

Thanks for crashing Gamejolt

This.... Looks..... AMAZING!!!

Of all Clover animations I've seen so far, this one's definitely the best

It was worth the several years of waiting. Highly anticipated fan game projects are rarely completed, so I salute the project members for their efforts. This is fantastic.

GAMEJOLT IS DOWN LOL

这游戏仅仅是玩一下里面的特殊机制和分支就能感受到程序会有多复杂，更何况还有大量优秀的美术贴图，悦耳的音乐以及巨量的文本，这么优秀的作品能在10年内完成真是个奇迹

RIP GAMEJOLT 😂

I’ve liked this fan game so much that at this point I consider it a canonical prequel to undertale.

Hey! Make another game about other soul! But like.. this game will happen after Undertale yellow (pacifist) ending , I really will wait for it like my bday ^^

this looks like a nintendo trailer

This release made my son's day. The trailer looks great! Thanks for all your hard work!

So,this is what happens when clover dodges an attack.

0:44 made me laugh HARD

Definitely another masterpiece

How do I put this game in words... Hmmm.. How do I say this, because the only thing I can describe this game as, is how the kids would say: *FRESH AS HELL.*

My god, I never thought I'd see the day where not only a fully original and great Undertale fangame is made but it's actually a full videogame rather than just skipping everything until you reach sans. Beautiful!

The animation is such a fitting homage to Temmies Artstyle, awesome!

I wish toby confirms this as canon 😭

Holy crap, I completely forgot that Undertale Yellow existed! I remember playing the demo 7 years ago when I was a sophomore in high school. Didn't realize that development was going on all this time!

Just finished the game for true pacific, if you and your team reads this then let me just say….what an incredible game you have made, these 7 long years have been worth the wait indeed. The way you guys made me feel the same emotions for these characters just like undertale did when I played that the first time is insane. Honestly me and ALOT of people think this should be canon, Toby himself should play this game it’s that good. Thank you guys so much for putting in so much hard work into this, you guys deserve a HUGE break. If this is the end for your team it makes sense after how long this took, but if not and you guys will make more stuff (even if not UT related) I promise I’ll be waiting for what y’all make next. Stay safe and once again, thank you.

Yo that's crazy, they have a gumoss from palworld in the trailer

To the team behind this game, thank you. The first demo was released 7 years ago. So much work to put into, so many ideas scrapped, and so many hours dedicated to a passion project. At any point during those 7 years you could’ve quit, much like most other hundreds of fangames that never saw the light of day. But you didn’t quit. This game being released is a testament to the strength an online community can have. You pushed onwards through sheer passion, dedication and of course, determination. Thank you.

I forgot the main character is a kid and we have a gun

0:39 is the cutest thing ever

Welp Yellow is definitely bringing the community back.
