Undertale 10th Anniversary Build Devlog 1 - Updates from the starter day


9/22/25 Devlog

Started today, already made the toy knife room larger with the transition to old home, started making old home, with a possible early build with it 100% complete even with the pacifist epilogue in some days. Replaced the starting story with a 10 years homage and changed the splash Undertale logo to the anniversary one. Tomorrow ill finish old home, then starting doing the post pacifist epilogue.

Toby fox just released a simple demo of the Official build, its only the pacifist sans battle and the dog residue dungeon monsters, you can run it directly on the website, feel free to check it out!

Been working lately on lots of 'behind-the-scenes' boring stuff that no one really cares about, so here’s a guy playing the sax for some reason.

I have added rewards for quests so that villagers can give you something in return for your hard work helping them. 🥳

I want to know - what's your favourite quest reward?

Heya! I wanted to show some gameplay progress i made so far. I hope you like it ^^

The whole squad is here!

Interested? Follow me!

A house I've built a while ago. :)

It nicely separates the snowy biome from the grassy one.

It's built with painted Ebonstone.

If you have more of an acquired taste, the restaurants in Niravasi have you covered! Maybe skip the salad bar, though.

Very ambitious construction going on in Planet Zoo on Plays today. We're tryin'. LIVE: www.twitch.tv/dreamhackplays
