Map of Security Outpost
Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.


Follow the steps up to a blue floor then proceed west to a door. Open the door to face zombiemen (or shotgun guys on Ultra-Violence (UV) and Nightmare (NM) skill levels), then continue forward to get outside and follow the path east through the nukage. Head south up some steps then east to a lift, which you can ride down to find zombies/imps guarding the exit door. Open the door to find armor bonuses along with the exit switch.

Other points of interest[edit]

When you reach the blue-floored area at the start, look south to find an armor.


  1. Open the first door you find and look left (west) and press on the silver section of wall to find health bonuses. (sector 33) In multiplayer, this secret also contains a medikit.
  2. Open the first door you find and enter the side room on the right. Go to the button by the window and use it, then head back to the starting point to find the south wall inside the nukage is open. Go up to find a megaarmor, as well as three piles of shotgun shells on UV and NM. (sector 50)
  3. After using the switch in secret #2, go to the room just before the exit room. Look north and use the green wall that looks different, then go up to the hall to get this secret. (sector 39)
  4. In secret #3, walk west as if you are going outside and a door will open. The north-east corner will be open. Enter this area, then head outside to the west. The northern platform will have lowered, allowing you to get a shotgun, shotgun shells and a medikit. (sector 11)
