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.
Demon Eclipse is a Doom II mod for GZDoom currently being worked on by Eriance. (The currently-available version contains episode 1 and 2.) The mod is intended to be a retelling of the original Doom experience through the eyes of another Marine. You, the player, progress through the usual "tech-base to hell" style gameplay found in the original Doom. Originally meant to be a four-episode project, the mod has been shortened to three episode for a tighter focus. Ideas for three more episodes are being planned for a possible sequel.
