UNDERTALE
A small child falls into the Underground, where monsters have long been banished by humans and are hunting every human that they find. The player controls the child as they try to make it back to the Surface through hostile environments, all the while engaging with a turn-based combat system with puzzle-solving and bullet hell elements, as well as other unconventional game mechanics.

Sorted, filterable and paged. Every link goes to the author’s own download.
- Mods385A mod changes the game itself. It needs something to load it, it may need other mods first, and it only works on the versions its author built it for.
- resource packs130A resource pack replaces the textures, sounds, models and language files the game ships with. It changes nothing about the rules, so it is safe on a vanilla server.

Why UNDERTALE mods break
A mod is compiled against one version of a game. When the game updates, anything that reached into the parts that moved stops working, and it usually stops working silently rather than with a message that explains itself.
That is what the table above counts. It is not a guess: each row is a mod the community has reported as broken by that specific release. The number is a fair measure of how disruptive an update was, and it is the reason people delay updating a game they have modded heavily.
Common questions
Does IndexGG host UNDERTALE mods?
No, and it never will. Every download link points at the author's own page on Nexus, GitHub, CurseForge or wherever they published it. We index the ecosystem; the files stay with the people who made them.
Where does the compatibility data come from?
From the communities that maintain it in the open, not from guesswork. Each claim carries how it is known, so a reported breakage is never presented as though the author said it.
Why is a mod listed as broken when it works for me?
Compatibility depends on your exact game version and the rest of your load order. A mod marked as broken in one release may work fine on an older one, which is exactly why the version is recorded next to the claim rather than a bare yes or no.
