UNDERTALE: Extended Underground: Team Applications Open!

(please read the article for more info)


Hello everyone.

When I started working on this mod, around 2024-2025, I Worked it entirely alone, and while I had finished Catacombs, I still need try somehow program most of the stuff on it.

The problem is that... I'M TERRIBLE PROGRAMMING IN GML

While I have some pretty well knowledge of Art and Pixel Art, Programming is more complicated for me.

Since the best I've programmed there are dialogues and some changes with teleports.

The same applies with the musics, since I barely know stuff about music.

So, I thought about opening applications for people join the mod team. So If you have some knowledge about music, programming or any other stuff, you can try somehow help the project.

Expect that there might be a chance of taking much time to I revise some of your answers.

I promise I gonna make sure when the form is closed once until I come to a decision.

See ya!

Next up

these are the current npcs i've made for catacombs (as of now) - Gravey (can be battled while on Catacombs.) - Grimclops (can be battled while on Catacombs.) - "Slime Widow" - "Emo Beagle Dog"

another area mockup for my UT mod. UT:EU - Summerlands "A Tourist Trap of the Underground. With a shining ocean, a very harsh sunlight." "Why not play volleyball there?"

UT:EU - Marshlands (v2 mockup)

"A dark sister location of Waterfall with a dark teal palette, much more is umid than Waterfall, but where sometimes, you can find dandelions there."

"But you might gonna find someone familiar there..."

It sometimes sucks that I need simplify the coloring of some assets, to try fit with Undertale artstyle. (then vs. now)

I made it to put borders for the mod!

The main issue about this, is that sometimes the borders might not work sometimes.

So the screen keeps on the original size, instead the one with borders.

But it might can works sometimes.

A quick update: Made some changes on Muchiel's house to look abandoned. Also, I'm still thinking about Catacombs Monsters design, this is "Gravey", a living gravestone.

A quick explanation of how the Train system gonna work on the Extended Underground mod.

"Why not use a raincoat instead of a umbrella?"

a random idea i had about Frisk wearing a raincoat on Waterfall

(Mockup for my UT Mod) UT:EU - Hotland Depths. "Below 200 meters, there's a very difficult area to inhabit from Hotland, with some parts having a toxic gas. This area has a pinkish hue due to the chemicals in the acid from Steamworks."

UT:EU - Autumnia Mockup (v3) "First accessed via a train station on Snowdin, Autumnia is a sister location of Snowdin, a cozy area but also mildly dark, and where a Halloween-like event happens in a village there."
