Underswap Broken Promise | UNDERTALE Fangame 

I love this game's idea, Sans was just acting like an exaggerated version of US Papyrus, but inside, he was always like the OG one, and he has to break character to stop YOU.

UnderTale: Your gonna have a bad time. UnderFell: Your gonna have a good time. Underswap: *We are gonna have a neutral time.*

when he says your face looks like you've done this countless times means that he seems to suspect you've battled a lot of fangames doing genocide.

I mostly like how this Sans is depicted.

I like how this game handles the whole memory thing in Disbelief's phase 3, it's much more short and simple. No need to pull a fake out about the dead characters coming back, just having Sans use attacks in memory of them is all it takes to incite that guilt of the past in you.

Sans: Oh, so there's someone good inside you? Sans: Not anymore.

When nobody says first: finally inner peace Homestuck megalovania YESS.

I love the way the sans dialogue sprite is like Classic Papyrus's sprite, looking sideways a little bit, like 80 to 75 degrees

I really like how you mixed Underswap with a different kind of Disbelief version, and then add things from the original Sans

*You realize sans’ eye is changing the normal blue and yellow color to an orangish-reddish color. The grin...the eyes...the attacks... They’re so familiar... Sans is breaking the laws of this au!

14:24 it almost looked like a jumping kangaroo xD

I love the concept so much I also love the fact that he uses DT to defeat you

I don't see the problem with US!Sans having a bit of original sans's personality, as well as other characters, because character's appearance and personality are one together, so US!Sans could dodging or go wicked sick is normal, he is sans afterall

Basically sans fight except looks harder.

The homestuck/earthbound megalovania, yes finally someone use that!

For some reasons, I get the feeling that this fangame shows how Undertale turned into Underswap.

Name: Broken Promise Sans: *acts like TS!US Sans* *Confused screaming*

Swap sans but it’s original sans

12:05 Wow I'm surprised or really not that much and I don't know if someone already mentioned this but as a Dragon Ball fan I have to point out the fact that Alphys is LITERALLY WEARING VEGETA'S ARMOUR

I love how this version of Underswap Sans is depicted. He's not a mindless, cute and more hyper version of undertale Papyrus' personality, as many artists portray him as; he's more like undertale sans, which would make more sense, since it's a role-swap and would kinda need a bit of the OG Sans mixed in. This game creator didn't make US! Sans like a child that is literally meant to be the older brother, they made him more 'Sans' and kept that lazy, apathetic and vengeful behaviour of Sans. Like, "You hurt my brother and kill everyone? Nup, fuck you, get dunked." I really, REALLY like this version.

Seeing sans has given up his act is bone chilling

"Broken promise" sounds like a thing id title a video of me getting scammed.

"honestly, it makes it kind of hard to give it my all."

Me: this fight looks familiar to the original The game : this is underswap

Start Fight here cause it Takes a long time to start 4:21

Sans:"A promise to follow on his footsteps" My brain prosesing :"wait didn't papyrus died here...." Proses completed Me: NO SANS DONT FOLOW HIM TO THE AFTER LIFE!!!

This feels to just be one of the most in-canon accurate takes that there is. TS!Underswap does a good thing on its own, but this feels more like the culimination of pure vanilla Underswap, and it's done well. Papyrus, for the little that we really see of him, does still seem like Papyrus in the end, a powerful, but big hearted, kind soul, one who's overall kindness cost him in the end. Even Sans here, the idea that he went to act more like Papyrus, it makes sense, it shows to an extent a more optimistic version of the Underground, one that i'd hope would be reflected more, something that insofar, TS!Underswap shows well, and I'd imagine a full take of this would do so too. Honestly the only thing I'm not a 100% sure is, is this implying that Sans swiped some of Undyne's determination experiments or something? Considering how the red leaking from his eye, and how he literally melts when dying, it's... definitely something that differs, but then again, feels Sans like to an extent. Overall, it's definitely something that is unique.

underswap: papyrus has sans personality and atitude ts!underswap:papyrus acts like ut papyrus and sans act like sans but teams are switched

I wonder who can sleep better classic Sans or underswap Sans

To be fair, this would be his theme, because he’s normal is passive Megalovania

It's like if sans wore swaps clothes and that's it.

I fear nothing.. except that.. Sans had an eyesore It scares me..

I like how his face went of Underswap sans to Undertale sans

Pog, the Homestruck megalovania

So, it's basically sans fight. Alright

Ok,everyone's gonna ignore the fact that the theme is the 3 megalovanias mix.

Heya Im the one guy that comments before the livestream even started yea i suck

This Is just ts!underswap with the aspect of cannon!swap

Look like roleswap Cuz swap sans never used telekinesis,and when papyrus is sans he gives a chance when he would never give after tons of geonocide routes

I swear there are more swap sans fights.than swap papyrus fights, and swap sans is technically a papyrus

Wow I didn't thought blue would be that strong

alternate title : sans with homestuck music

This is underswap But papyrus more like papyrus And sans more like sans and i. m comment 69

I like the cutscene lol

If underswap sans was more like sans.

Swap papayrus be like:👌

bgm : Homestuck - MeGaLoVania (2009)

US!Sans : Personality change, power change TS!US Sans : Personality kept, power change This: TS!US Sans but HAHA PAPYRUS DIE I BREAK CHARACTER Seriously though, the game itself is really well made!

under"dont swap the character's personalities, just the places they are and the designs"

I would call this a changed canon swap or TS Underswap

I thought of a new au *undertale*

Underswap sans acts like undertale sans lol but nice video and the attacks are different

this sounds like undertale all over again

"here goes nothing" Proceeds to do nothing

1:15

Oh, UnderSwap sans like UnderTale Sans -_- .... ... How?

Atleast the game is complete

Underswap sans literally broke character so he could try and stop you from eradicating monsterkind. A true hero if you ask me.

This is more of undertale but instead a twist

Undertale=disbelief Underswap=broken promise

This just seems like a bad time with extra steps

Mr beast sans is popping up in my head after I saw the name

So basically THIS underswap is a role switch but not a personality switch But the imo better underswap is role and personality switch

There's high quality Homestuck megalovania

Finally, a game with canon underswap sans.

I thoight its dusttale cause moonlight and remeber that comic about swaptale US paps try to be UT paps cause he died now i think US sans died and UT sans wear his armor

Is megalovania of the home stuck

0:22 Spanish: *No*

Why does Sans have blood on his head?

Us sans but it was an act all along.

Distrust with serious us sans? Nice!!

Why is everyone talking about what version of Underswap this is? It's an Undertale fangame where you fight against Sans, dude. Enjoy it, or don't. It doesn't really matter.

What is the mame the soundtrack

Blue berry sans face turn into classic sans face lol

Nice

why blue have the older version of megalovania?

so (original) TS!UnderSwap sans DisTrust

love the alphys sprite

that look like underswap sans x sans

So this is litteraly the sans fight just in swap

hi

Uhh... Does he just use Earthbound Halloween Hack version of Megalovania ? XD

the swapswap

Underswap Broken Promise is just like disbelief or Undertale The unseen ending or the revenge thingy ( i forgot lol)

Who is that one odd one's out who disliked this

hold up is this earthbound HH megalovania

The best distrust game

ОK it's sans battle but it isn't sans battle

Nice akt but why are you killer? Be pacifist :)

Yeah thats the stuff😎😎😎😎😎👍👍

It is nearly like sound of Earthbound: Halloween Hack(phase 1)

also, crap! this version of underswap sans is way very OP! it has a cool special attack, he gets so determined that looks cooler, if he went dusttale mode then he could beat up error sans, bill sans, dusttale sans, core frisk, ink sans, seraphim sans, ultra sans (that one with the orange soul), and a lot more!

if this is underswap... why does he wear slippers

I like how they just used homestuck megalovania cause swap sans dosent have a megalo.

Blue berry is not timelined papyrus is

Sans acts like undertake sans. Same to papyrus.

I'm assuming this is basically TS!Distrust

Elho

Why homestuck/earthbound

He looks like blue.
