STR27: Cyclone is the twenty-seventh map of Stronghold: On the Edge of Chaos. It was designed by Daniel Gimmer (Tormentor667) and uses a custom music track.

This level uses the "Milestone" mode, where the objective is to prevent monsters crossing a series of milestones on their way to the deadline.


Map of Cyclone
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.


In this level, monsters will initially spawn from a magma crack at the south end of the level; they will then head east and north through an outdoor area, west through a large cavern then through a corridor and up a winding staircase before heading west to the deadline.

  • The first milestone is the entrance to the cavern. Once this milestone is breached monsters will start spawning from the north side of the outdoor area, heading east and south to enter the cavern.
  • The second milestone is the door to the corridor leading to the winding staircase. Once this milestone is breached monsters will start spawning on the north side of the cavern.
  • The third milestone is the second pair of steps on the winding staircase. Once this milestone is breached a wall will lower at the bottom of the staircase, and monsters will start spawning from a closet behind this wall.

Players will start in the deadline room at the west end of the map; this room contains weapon, ammo and health pads as well as a teleporter leading to a room that contains a second ammo pad, and connects with the cavern and the monsters' first spawn point. If you walk through the door by the teleporter and turn left you can follow the ledge to a second health pad. There is also a weapon pad at the cavern entrance, a powerup pad by some crates inside the cavern, and an ammo and health pad in the corridor leading to the winding staircase.

A rocket launcher is placed on the ammo pad in the starting room, while a shotgun and shells can be found at the top of the winding staircase.
