Back to Saturn X

Back to Saturn X is a megawad and partial conversion for Doom II. It features an exclusive texture set and a new palette and color map (which degrades less the colors in darkened areas; but which required replacing the sprites with copies adapted to the new palette).

Song titles from provide the title, episode names, map names, and are also inserted into storyline text.

The first episode was released on December 10, 2012, for Doom's 19th birthday, and features twenty levels, one secret levels, and three "hub" levels corresponding to the same area revisited to access different zones of the Saturn X base.

Two additional episodes are planned, each as an independent megawad: the unmodified Doom engine not allowing to have more than 32 maps normally playable.
