STR19: Tarstone Fortress (Stronghold: On the Edge of Chaos)

STR19: Tarstone Fortress is the nineteenth 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 "Limit" mode, where the objective is to prevent too many monsters crossing the deadline.

Essentials
All players start in a cross-shaped hall; the deadline is the red flesh-gate south of the start point, and you must not allow more than 50 monsters to pass through it. There are six item pads - one weapon, one powerup, two ammo and two health - in the central hall, and a second powerup pad in an outdoor area to the north. From here you can head south-west or south-east to find lifts leading up to chambers with another health and ammo pad.

Monsters will initially spawn from a dark room in the south-east corner of the level, then follow a passage up to the central hall before heading south-west to the deadline. From wave four monsters will also spawn from a cavern in the south-west corner of the level, following a tunnel north-east to the central hall.

The narrow passages corral monsters, making them easier to hit with landmines and the rocket launcher; however, they can make it harder to avoid incoming attacks, particularly from cyberdemons and bruiser demons.

A shotgun and a box of shotgun shells can be found north-east of the start point, while a chaingun and two boxes of bullets can be found in a crate south-west of the start point.

Completing this level will award 1,800 bonus credits.

Other points of interest
A rocket launcher can be found in a room above the central hall, overlooking the west spawn point. You can get there using the lift south-west of the outdoor area.
