Other points of interest[edit]


  1. Climb the steps at the start and make your way to the south end, where the switch will disappear on approach and you will see another switch. Use the wall to the east of the switch for a teleporter, telefragging a cyberdemon as you enter. (sector 297)
  2. Leave Secret #1 to go back to the switch area, and you will see that the northeast corner is open. (sector 99)
  3. In Secret #2, go to the northeast corner of this area and look southwest. You will see a switch behind the blood. Shoot it to reveal more monsters and a switch that will allow you to leave. (sector 97)
  4. In the red key area, two closets will open up to the north and east. Enter the east closet and look north for a switch to shoot. After shooting it, go back to the starting point and into the new passage where you will find a medikit (Hey, Not Too Rough or lower), a medikit and two rockets (Hurt Me Plenty), or a box of rockets (Ultra-Violence or higher). (sector 418)
