STR20: Dusk is the twentieth map of Stronghold: On the Edge of Chaos. It was designed by KeksDose and uses a custom music track.

This level uses the "Deadline" mode, where the objective is to prevent any monsters reaching the deadline.


Map of Dusk
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.


This level is set around an oval stone walkway; players one to four will start at the east side, while players five to eight will start at the corners. Inside the walkway is a grassy area; the four item pads can be found at the west side of this area. The deadline is located behind players one to four as the level starts.

Monsters will initially spawn by the north-west and south-west corners of the walkway - the monsters in the north-west corner will head east along the north side of the walkway (sometimes heading south and east along a bridge running through the grassy area), while the monsters in the south-west corner will head east along the south side of the walkway.

  • For wave three, the existing spawn points are removed and the monsters will spawn from the center of the grassy area, heading east to reach the deadline.
  • From wave four, the monsters will return to their original spawn points and a third spawn point will open by the north side of the walkway.
  • For wave six, two more spawn points will appear on the west edge of the level and north of the building containing the deadline.
  • For wave seven, the spawn points on the north-west, south-west and north sides of the walkway will be removed, along with the spawn point north of the deadline building.

This level focuses on fast-moving enemies; ensure that all paths are covered and be ready to return to the deadline if the alarm sounds. Consider placing a couple of sentry turrets near the deadline to eliminate enemies that get too close.

A shotgun can be found in the deadline building along with three piles of shotgun shells.

Other points of interest[edit]

Use caution around the outer areas of the level, as falling off the edge of the map will result in instant death and the loss of a life.

Leave the deadline building and turn right, then turn right again and jump over the blue sloped sector in front of you. You will land on a brown floor with an octagonal hole - drop through the hole to land in a room with a chainsaw and two rockets.

A marine reinforcement powerup can be found on top of the archway in front of the deadline building. Ride the lifts either side of the archway up, then jump from the balconies to reach the powerup.

At the top of the slope near the north-west corner of the walkway is a depression in the floor. Step on it to be carried down to a hidden room containing a computer area map.


  1. Go to the south-east corner of the walkway and jump on to the outside wall, then look down to see landmines on top of a rock pillar. Run forward and immediately jump to get enough momentum to land on the pillar. (sector 794)
