STR24: Aurora Emitter (Stronghold: On the Edge of Chaos)

STR24: Aurora Emitter is the twenty-fourth map of Stronghold: On the Edge of Chaos. It was designed by Paul DeBruyne (skillsaw) and uses a custom music track.

This level uses the "Limit" mode, where the objective is to prevent more than 100 monsters crossing the deadline.

Essentials
You start the level outside a large building; the deadline is a blue pad at the top of a spiral staircase inside this building, and you must not allow more than 100 monsters to cross it. Weapon and powerup pads can be found on this staircase, while health and ammo pads can be found just before it; health and ammo pads can also be found outside, on the east side of the main building.

Monsters will initially spawn from two magma pools on the south and north-west sides of the level, but from wave six the two green light beams near the building will turn red and monsters will start spawning from these as well. In the early waves, focus on the monsters spawning from the south area first as they have a shorter route to the deadline; later on, stay near the deadline and attack the monsters as they congregate by the light beam inside the building. The main building has three entrances and monsters will use all of them.

A shotgun and two stacks of shotgun shells can be found at the bottom of the stairs leading to the deadline, while a chaingun and a box of bullets can be found outside at the north side of the building.

Completing this level will award 2,300 bonus credits.

Other points of interest
Do not step into the green/red beams; this will result in instant death.
