The Lost Episodes of Doom is a collection of three eight-level episodes for Doom by Christen Klie and Bob Carter. It takes place on the Jovian moons Callisto and Io, and on Jupiter itself. It was a commercial product and was included on a 3.5" floppy disk that was sold with a 246-page book that details the levels. The book is written by Jonathan Mendoza with some notes by both map designers. The book was published by Sybex in January 1995.
