Abyss Tubes

The earlier version of this page used made-up depth values. This version keeps the useful part: which tube upgrades are actually worth caring about as you push into harder routes.

Early Upgrade

Pufferfish Tube

Public guides frequently point to this as the first tube that meaningfully improves exploration.

Midgame Upgrades

Boat Tube, Zepline Tube, Lost Spirit Tube

These are the tubes most often mentioned when players want to bridge into deeper progression paths.

Late Upgrades

Ruined Tube, Banana Tube, Wild Tube

These are repeatedly cited in late-game progression and public tier discussions.

How To Judge A Tube Upgrade

  • Can it unlock a route you were struggling to reach before?
  • Will it stay useful for more than one short stage?
  • Does it pair well with your current race and gun path?
