Just the full ost of the animation that I will use for the animation of Undyne The Undying in Undertale Last Breath. I remind you that it's not official but it's a boss like others that I would like to see in the game if Zer Jox in the future decides to add other chapters. I hope you like this Undyne The Undying Full Ost, it's a fan project about Hard mode Undertale Last Breath. This time, Undyne genocide will be much much harder, it will be a real HARD MODE, more hard than Sans Last Breath Chapter or the difficulty of Undertale Last Breath.
