Same controls as in the real undertale: arrow keys to move. Thanks to toby fox for undertale, the wonderful game it is. NOTE: This is fan-made by me in my spare time, it does not go down in the actual plot line. S T O R Y: The undertale character has NEVER done a pacifist run, and has only done neutral and Genocide, many, many times. One run, after killing sans and being back-stabbed by Chara, the player ends up in an empty void after they reload their game and try to do another Genocide run. They walk aimlessly to see a mysterious skeletal figure... who looks eager to get their revenge.
