Huh? Who are they?
N-nobody else is s-supposed to be here...
Oh well! We can't worry about that now!


CORE Approach is the 64th track in the Undertale Soundtrack. This short track plays in the room that separates the MTT Resort from the CORE. This track is composed of quiet, echoed guitar chords from Hotel with similar ambient wind sounds as those that can be heard during the Leaderless Ending.


  • Though Hotel is slowed down in the Genocide Route, CORE Approach is not.
  • The wind samples in this track would later be reused in Deltarune, serving as ambient background noise on King's battlefield before Gallery plays.
