A downloadable mod

Hey, make sure to check out the DELTARUNE version of this mod!


It's Undertale, but every SFX is replaced by text-to-speech voices

And I mean every sound effect, even some music as well! The TTS voices have been manipulated in such as way as to make it sound close to the original sound effects, so it isn't just some voice saying [DAMAGE SOUND] or something.

This mod is actually more than a year old and had been sitting on my computer for a while, but now I've decided to release it. So enjoy, I guess!

(Also this mod contains some swearing)

[Instructions on how to install this mod come with the download]

Credits and Stuff

Anyway, enjoy the mod and stuff!
