SAVE Point in the Ruins

Ruins is the 5th track in the Undertale Soundtrack. It plays while the protagonist travels through the Ruins or 38% slower as "An Ending" after defeating Photoshop Flowey.


  • This song has similar instrumentation and feeling to "Fortress of Ancient Dragons" from Chrono Cross. As both songs play in ancient ruins, it might have served as an inspiration.
  • If you speed the song up by 2x, it sounds very similar to Spear of Justice and NGAHHH!!
  • Ruins appears in tracks such as Waterfall, Spear of Justice and An Ending, among many others.
  • There is an unused version of this track, called mus_ruinspiano. It is a slower piano version of Ruins.
  • The OST version lacks the very last note that plays before the song repeats in the game.
