- Ulu Estate
Ulu Estate is a suburb at the very edge of the city. Many monsters with the level of 90 through 150 are found in the estate. Buildings in the estate appear to be apartment complexes that have been overrun by monsters and nature.
Many broken down cars, fallen light poles, and trash heaps are spread through out the city. The deeper you go into Ulu City, the more buildings are damaged by nature and the monsters.
- Destroyed Park
Destroyed Park is the heart of the city, which lay in ruins that are rapidly decaying. The Park is now home to colossal tree-like monsters: Duku. They lurk through the park with great malice.
- Ruins of Krexel
The Ruins of Krexel are a part of a most dangerous area in Ulu City. Most buildings are filled with traps. The buildings are overrun by a huge tree monster called Krexel; it is also the boss of Ulu City. Currently the ruins are avalible from a quest to fight krexel.
