MAP23: Evil System is the twenty-third map of Swift Death. It was designed by Franck Livolant (franckFRAG) and uses the music track "The Demons from Adrian's Pen (remix)," originally composed by Robert Prince for Doom and remixed by Jay Reichard (silentzorah).

Other points of interest[edit]


  1. Strafejump south from the start across the platform with the shotgun guy (chaingunner on Ultra-Violence or higher) and from there to the small slit in the wall. Then carefully make your way onto the ledge with the blur artifact. It may be easier to reach this ledge via an arch-vile jump, but take note that you will miss your chance at this secret if you jump down below. (sector 39)
  2. Jump into the nukage at the east side of the map and spot the soul sphere in a dark alcove. (sector 42)
  3. Gently walk off the ledge at the start and a wall of revenants opens up next to you. The platform below that has a mancubus and some stimpacks, which you can jump down to from a number of places, such as Secret #1 or the ledge at the northwest end. (sector 50)
