General information

GOG.com Community Discussions for game series
GOG.com Support Page
Celestial Heavens' subforum


Source DRM Notes Keys OS
Prompts for answers from manual, code wheel, etc.
Manual lookup copy protection. Use DOSBox.
Mac OS
Bundled with games 1-6. Pre-packaged with DOSBox.[3]
Retail versions need the manual to answer copy protection questions; the GOG.com version bypasses the questions.

Essential improvements[edit]

Where Are We[edit]

Supported by Where are we, an automapping and reference utility.

Grid Cartographer[edit]

Supported by Grid Cartographer. Its Game Link feature assists in creating the game map. This is not an automap. From the Grid Cartographer's documentation: “This approach enhances the immersion factor by allowing you to draw the map as you perceive it, not revealing every secret ahead of time. Hidden doors remain obscured, traps are left undetected and unsprung. It's still up to you to explore and record what you see on the map as you venture forth!”

  1. File/folder structure within the installation folder reflects the path(s) listed for DOS and/or PC booter game data. For the GOG.com release, file changes in DOSBox are redirected to <path-to-game>/cloud_saves/ even if GOG Galaxy is not used (this folder contains all redirected files, so some files in the cloud_saves folder might be temporary files or other files that do not contain saves or settings).
