About Undertale Fan Games - AU Fight

This is a game that includes many kinds of Undertale fangames.
There are many battles from different Undertale universes that were made by me and other creators.

We can kind of say this game is a collection of Undertale fan games.
If you don't want any of your work to be in the game, please contact me first.
But if you are a creator who wants to have their own game to be in this collection, you can always contact me to speak about it!

* Swapfell Papyrus fight | Dissension & Hypermaniac (Phase 1-2)
* Bad Time Trio Remastered | Triple The Threat
* Trios The Squabble | IT'S THE HUMAN!!
