New in current development version (1.3 preview 5):

  • New and revised graphics for weapons, enemies, allies, walls, landscapes, and terminals, many new in preview 4
  • A major overhaul of the game's third chapter, including a (largely) new level, "The Midpoint of Somewhere"
  • Complete redesigns of the levels "Remedial Chaos Theory" (formerly "Unwired"), "To Sleep, Perchance to Dream", "The World Is Hollow", "The Land in the Sky", "Floating in the Void", and "Where Giants Have Fallen", including a new "ghost battle" in several of these
  • A massively expanded soundtrack featuring work from eight new arrangers and more than six hours of music
  • New and revised story arcs, character arcs, and characters
  • Numerous improvements to pacing, game balance, level design, and weapons
  • New secrets throughout the game, including a new secret tracker
  • Over 100 of the game's 380+ sounds newly remixed in stereo directly from the CD-quality source files, including dozens of completely new sounds
  • A new final boss battle (of sorts)
  • More sophisticated monster scripting
  • Atmospheric weather like rain and snow
  • A complete remake of the game's Pfhor texture collection
  • A partial rebuild of "Haec caverna nón fórmátió nátúrális" (formerly "This Cave Is Not a Natural Formation" — the same thing in English)
  • New segments in numerous levels, including "Septococcal Pfhoryngitis", "Core Done Blew", "This S'pht Again‽" (formerly "S'pht'ia"), "Let Sleeping Gods Die", " deep the rabbit hole goes" (formerly "Eat S'pht and Die" and "Flight of Icarus"), "Pfhor får lamm", "Eádem, sed aliter" (formerly "Dread Not"), "Bug-Eyed in Space", "Run, Coward!", "Once More unto the Breach", "Echoes of Eden", "The Dead Live in the Catacombs", and "Dark Grotto of the Lethe" (formerly "Deep into the Grotto")
  • A new "quick save on game transition" feature
  • Deliberately pretentious uses of grammatically questionable Latin to an extent that may qualify as self-parody

Much of Eternal is available for public development. We have historically used GitHub as our main repository, but that is currently outdated, as interim development is being handled through Dropbox, with a Split Map Folder and a Current Build Folder.

If you'd like to help improve the project in any other way, please write to and we can provide you with any source files (such as AIs and PSDs) that you may need for whatever it is you want to improve.
