The Moon Stair is here

The artifacts of plant and time,
crust and fuzz with lossy compression,
doze in moonlit marble beds,
touched by august muzzles.
The past is unwritten as the future,
And what is left, broken and changed,
to be tended by the point Colossi and their swarm.

-Daughter Erinna, Modulo Moon Stair and the Tree of Life

This major feature arc adds the last late-game region, a new leg in the main quest, new UI, all new sounds, and more. Here are the full patch notes.


  • There is now a new quest after returning from the Tomb of the Eaters. Talk to Barathrum in his study to learn more.
  • Added a new system for the creation of [redacted] in support of this quest.


  • Added the last late-game region: the Moon Stair.
  • Added new creatures: zero jell, unimax, dawning ape, n-dimensional starshell, dreamcrungle, glow-wight apotheote, monad, and dream wren.
  • Added a new village-like location -- Chavvah, the Tree of Life -- with several new NPCs.
  • Added a new side quest at Chavvah.
  • Added psychic biomes, limited to the Moon Stair.


  • Added a new Pixel Perfect mode, which forces zoom to snap to a perfect multiple of the pixel art. You can toggle it in the General options menu.
  • Added a new Docked mode that locks the combat log, nearby items list, and minimap. You can toggle it in the General options menu.
  • Added a new 'Flip' mode to the modern dock. It has behavior similar to the original text sidebar.
  • Added a new mouse cursor and an option to disable it or choose an alternate color scheme (Options > Overlay UI > Mouse cursor).
  • Added a new option for "Play area scale" with three choices.

    • Fit - fits the whole play area on screen. May necessitate letterboxing.
    • Cover - ensures the play area covers the screen. Minimizes letterboxing.
    • Pixel Perfect - sizes the play area to an integer multiple of the pixel art. Maximizes sharpness.

  • Changed the default setting for the modern UI play scale from Fit to Cover.
  • General UI note: if the camera is zoomed in so that the whole play area doesn't fit on the screen, you may notice the UI switching to fullscreen Fit mode when you take certain actions that still have unfinished UI elements (like Interact nearby). This is done to prevent the old UI elements from becoming unreadable at the zoomed in scales. As we add continue to add modern UI elements, it'll stop happening.

  • Added a new target reticle for some contexts.

  • The mouse cursor now hides itself when the mouse is stationary.
  • Added an option to disable mouse zoom.
  • Removed option to show tooltips when looking. It's now always works this way when the modern UI is enabled.

  • Added a tooltip to the window layout lock button
  • Look now is now bound to left stick button by default in the modern input manager.
  • After firing a ranged weapon, your target for future shots is now more reliably what you shot at instead of what you hit.
