Back To Saturn X is an imperfect megawad. The texturing and color pallet changes are only matched by Ancient aliens, and on the texturing front Esselfortune helped with the AA texture pack as well. The first chunk of the wad is brilliant, and so is the final 3rd. But the middle portion is long and somewhat mediocre, I would spend days pushing through a single map. The wad is recommended with an asterisk that you will need to power through some maps that could have done better if cut in half.
