E2M9: Descent into Darkness is the ninth and secret map of episode The Collider's New Clothes in Return to Hadron. It was designed by Matt Powell (cannonball) and uses the music track "Adagio for Strings and Organ," originally composed by Remo Giazotto and arranged by Lee Jackson for Rise of the Triad.

Other points of interest[edit]


  1. At the bottom, go towards the big marble block at the north end of the cave. Go to its northern side and press on it, then quickly run back to the center and enter the teleporter before it closes to reach a megaarmor and boxes of rockets. (sector 11)
  2. Look towards the marble steps that lead up to the red bars, then go around the north column. Notice that the north side has a blue light instead of a red light, unlike the other sides. When you press on this light, quickly run to the south side of the marble structure and enter the teleporter before it closes to reach a ledge with an energy cell pack and a soul sphere. (sector 148)
