Honestly I love UT: Betrayer, I can't remember the full story but I believe it was using the concept of the Failed True Pacifist Run, which happens in Undertale when you do the Genocide Run first then do the True Pacifist Run, which causes Chara to take control and kill everyone in the End. I loved how the AU used that as the concept, I just hope one day it comes back or perhaps other AUs like it come out. Anyways enough of me rambling, I hope ya'll have a great day and remember to keep up the hope.

I'll also upload the original UT: Betrayer OST, if my depression let's me lol
