Age of Empires IV:
THE KHMER EMPIRE
The Khmer Empire, also known as the Angkoran Empire or "Kombuja", was the dominant power in Southeast Asia throughout the Medieval era. Though much of their history is lost to time, they remain a popular a mainstay in many historical strategy games, including Civilization and Age of Empires II. In this concept, I gave them a Zerg Creep-like mechanic called "Wetlands". Additionally, they can build the Siege Workshop in the Feudal Age, and can have access to the Ballista and Ballista Elephant unique units.
