There is even Trainertale, an AU based on Pokemon and Undertale. Sans Simulator is a fan-made free battle game, while Underfell: Revolution, takes place in two locations. Similar AU spin-offs of Undertale include Undertale: The Second Chance, Underswap, Deltarune, and Unitale. Conversely, other characters that were good in the original Undertale are now bad in Underfell. In Underfell, however, the friendly monsters have been replaced with malicious versions who want to do the player harm. It started life as a piece of artwork – or design aesthetic – showing a concept for an Undertale AU where everyone was evil and edgy before eventually becoming a game known as Underfell.įor those new to the Undertale world, the original game featured good-natured monsters who didn't want to hurt the protagonist. Undertake: Underfell was developed by The THI Team - THI Games as a non-profit and unofficial fan game based on Undertale.
