The Fortress is a special hunting area that consists of narrow canyons, a base camp, and the fortress. Here you fight the Elder Dragon Lao-Shan Lung and the giant Carapaceon Shen Gaoren. In some of the areas there are bridges, which can be used to jump on Lao's back for a few carves, as well as into Gaoren's shell, also for three carves.
The Fortress is armed with Ballistae, Cannons and a Dragonator in the final area. The Dragonator consists of 4 giant spikes that pierce the monster when the trigger is hit. Ammo for the Cannons and Ballistae are found at the Base Camp.
The only small monsters that live in this area are Ioprey, which must be evaded to bring the Cannon S to the Cannons. These Ioprey respawn only 3 times.
- It is only in Monster Hunter 2 where the Fortress is raining in a quest with Ashen Lao-Shan Lung.
- There is an Agito(or maybe a Wyvern Agito) and various crossbows displayed in the base.
