To go through this level, you have to flip the right switch in each big room that presents several switches to you. If you flip any other switch, you will have to contend with monsters.

The correct switches to press, in the order of the rooms you go to (and the monsters that appear if you flip any of the wrong switches):

  • Seventh switch from the right (five cyberdemons)
  • Fourth switch from the left (sixteen cacodemons and sixteen barons of Hell)
  • Fourth switch from the right, which will allow you to access the blue key (twelve cacodemons)
  • Third switch from the right (ten arch-viles)
  • Fifth switch from the left, which will allow you to access the red key (one baron of Hell and twenty revenants)
  • Second switch from the left on the south wall (eight barons of Hell)
