STR33: Antlion Nebula is the thirty-third map of Stronghold: On the Edge of Chaos. It was designed by Björn Ostmann (Vader) and uses a custom music track.

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

Walkthrough

Map of Antlion Nebula

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.

Essentials

Monsters will spawn from a cavern in the south-east corner of the map and follow a rock tunnel to enter the base - once inside, they will follow a single path up a series of bridges and ramps until they reach the top level and pass through the deadline. This map spans multiple levels and has overlapping bridges, so it is important to familiarize yourself with the layout.

• The first milestone is at the exit from the rock tunnel. Once this milestone is breached, monsters will start teleporting in just beyond it.
• The second milestone is at the end of the bridge on the bottom level. Once this milestone is breached, monsters will start teleporting into the passage beyond.
• The third milestone is at the top of the second ramp. After this milestone is breached, monsters will start teleporting in behind it.

All players start on the top level in front of the deadline. Head straight forward to find a chaingun and two boxes of bullets in front of a weapon pad; there are two numbered holes here that will let you drop straight down to the lower levels, but #3 will put you closest to the monsters' starting point.

A shotgun can be found in the outdoor area, a rocket launcher can be found at the bottom of the hole numbered 2, and a chainsaw can be found behind a column at the bottom of the hole numbered 3. Ammo and health pads can be found by the third milestone and at the bottom of the hole numbered 3, while a powerup pad can be found near the bottom of the hole numbered two.
