Map of Barracks
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.


From the start, proceed through the door, up the stairs, and into the computer room. To the player's right is a switch that opens an alcove marked with yellow and black stripes down the hall toward the northwest. Inside the alcove, another switch will open an area across the courtyard to the east. A third switch inside this area grants access to a path directly on the player's left, which leads to the red key. Once the red key is obtained, the player can exit the immediate area to find another corridor revealed. Follow this corridor to a door, climb the stairs on the left, and then turn left at the exit signs. Open the red door and flip the switch inside.

Other points of interest[edit]

A room at the west end of the map contains a computer area map, many armor and health bonuses, and several ammo pickups.


  1. Open the door at the start and head north into the computer room. Shoot the television on the left terminal, then head all the way to the northwest end of the hall. There will be an opening here with a soul sphere, backpack, or berserk pack depending on your skill level. This area counts as two secrets. (sector 123)
  2. See Secret #1. (sector 124)
  3. In the brown-floored hall at the north end of the map, go all the way southwest to a door, then use the wall to the west of that door. Flip the switch here, then go back across the hall to the switch with the lift. To the south, you can get a green armor. (sector 165)
