Deltatraveler is a Deltarune/Undertale AU fangame created by RynoGG, based off of the "GOD damn it Kris, where are we?" Meme. Taking place after Chapter 2 of Deltarune, the game follows Kris, Susie, and eventually Noelle, as they travel through countless worlds to find their way home. Comprised of 8 sections, each of them take place within a location of the following games:

  1. In Ruins: Undertale
  2. Valley Blues: Earthbound
  3. Hell's Forest: GG!Underfell
  4. Shining Savior: Legends of Zelda: A Link to the Past
  5. Mirror Mirror?: TS!Underswap
  6. Inside Job: Mario and Luigi: Bowser's Inside Story
  7. Gears & Gaffes: Toontown
  8. The Dark: LOSTCORE + Dark World

Each section has their own Genocide and Pacifist routes, though it's currently unknown if they have effects on the follow sections.
