The Lost Episodes of Doom

The Lost Episodes of Doom is a collection of three eight-level episodes for Doom by Chris Klie and Bob Carter. It takes place on the Jovian moons Callisto and Io, and Jupiter itself. It was a commercial product and was sold with a 246-page book that details the levels.

Massacre on Callisto
The first episode takes place on Callisto, one of Jupiter's moons. All of the levels in this episode were derived from Chris Klie's earlier episode, CHRIS_E1.WAD, and also appear in the later version, CHRISK.WAD.

Ultimate Doom
There is a well-known bug with the add-on. Since Ultimate Doom demos are not compatible with Doom demos, the add-on would crash if it were ran on Ultimate Doom. The solution is to start the game before the demo starts.
