Story in the mod

In the world of Undertale, a disaster has occurred: a nuclear bomb exploded, everything around became toxic and a huge amount of radiation in the air. Sans turned out to be one of the survivors, not far from the epicenter, but thanks to his device, the skeleton survived and now with new powers, he will fight Boyfriend, telling him about what happened to the music rhythm.
