The demons came and the marines died. Except one. Your are the last defence against these hell-spawned hordes. Prepare for the most intense mutant-laden, blood-splattered action ever! The texture-mapped virtual world is so real, you don't just play DOOM - you live it.
4 episode replacement for DooM (the 4th episode works only in Doom 2, the first 3 work for either Doom or Doom 2)
This mod is now for Doom 2 due to Episode 4, (the first three episodes are still playable with original Doom).
In January of 1995, a level set for Doom 1 was actually given a commercial release through a book sold through retail stores.
Dubbed, "The Lost Episodes of Doom", the book (written by Jonathan Mendoza and published by Sybex) contained a set of techbase style levels designed by Christen David Klie and Robert Kiana Carter, acting as a parallel story to Doom 1 by taking place on Jupiter and its moons. The book itself acted as, not only a strategy guide, but also insight into how the levels were made by Klie and Carter.
The purpose of this project is to reintroduce this classic level set by using features introduced in ZDoom to make the game feel more independent of its base game, and really delve into the science and story behind it. Actual research was done on Jupiter and its moons to up the presentation of this level set, by making the setting as close to Jupiter as possible, as opposed to Mars.
The text file included explains more on the story, levels, and features of the wad.
