AoE4 Civilization Concept: Khmer Empire

Hey! Here is my draft on the Khmer Empire.

And I actually enjoy doing these, as it lets me dig through some history texts and learn more about these Civs than I knew before.
Tried to keep the AoE2 flare they have but also add their own AoE4 flare to it.


Canal Infrastructure, Elephants, Economy

Difficulty: 2/3


  • Forestry already unlocked for Villagers

  • Research and Production buildings connected to canals have research and production time reduced by 10%
  • Canals need to be connected to a Baray to have any effect.

+Unique Landmarks

  • Koh Ker: Increases movement speed for all Worker elephants and functions as a Monestary from Castle Age.

Additional Notes:

The architecture should be similar to what we already have in AoE 2, with exception of Houses and Military buildings being made of wood. The houses are typical of those you find in South East Asia, even today. Being elevated from the ground

Naval units would be similar to how they look in AoE 2, the Junk-style ships.

Language progression: They would mostly hold the Old Khmer language, which is divided into 2, Pre-Angkorian (611-802) and Angkorian (802-1431) to the eventual pre-colonial Khmer Language. The difference between Pre-Angkorian and Angkorian is hardly noticeable, as they were pretty much the same. Developing into the more familiar modern pre-colonial Khmer Language in the imperial age.

Landmark references:

Koh Ker: Was briefly the capital of the Khmer Empire. At its peak, a great variety of statues were chiseled, many being plundered and stolen sold as stolen art in modern times.

Baray Teuk Thla: Also known as The West Baray**,** is one of the largest hand-cut reservoirs on the planet. These were not dug down as a whole but rather built up as tall earthen dikes. Played an important role for the Khmer to control the irrigation for farming.

Bayon Temple: Plays an important role in Khmer culture, it marks the shift from Hindu and Indian style culture, into a Buddhist one. The king at the time was a staunch Buddhist and started a process of shifting the religion into Buddhism. He build this temple unlike most temples of the time, without any walls, to signify that anyone, noble or peasant alike is welcomed. In contrast to the Hindu caste and class system.

Prasat Preah Vihear: This is a temple that has been fought over between modern Thailand and Cambodia for many years. A temple dedicated to the Hindu god of Shiva. Finished around the 11th century.

Wat Phnom: A wealthy old lady named Penh happened to find a floating koki tree in the river, when she and the villagers recovered the tree they found four Buddha statues and another statue in the form of Vishnu. She assigned the villagers to build a small hill and a wooden temple on top. This eventually grew and got built into the grand temple of today

Banteay Chhmar: This temple holds the story of how Prince Srindrakumara was protected two times by four companions in arms, against Rahu and another on a military campaign against Champa, The Four statues, with one of the princes that was placed centrally in the chapel.

Wonder: Angkor Wat: literal meaning being Temple City, is the iconic temple complex that marked the height of the Khmer empire. The temple is designed to represent Mount Meru, an important mountain the Hindu mythology similar to Mount Olympus in Greek mythology. With a large moat of more than 5km represents the Hindu mythological sea of milk. The temple held a very important role in Khmer governance as the Khmer king was seen as a God-king, and the construction of this temple was to firmly place the image of the God-King unto its people.



* Health: 200

Canal Bridge:

* Health: 200


Worker Elephant:

* Health: 700/1050
* Attack: 8 melee; bonus against Buildings +70 (Tusks)
* Range: 1 tiles.
* Rate of fire: 2.75s (Tusks)
* Armor: 0/15 Speed: 1 tiles/s

Worker Elephants Function as a light-battering ram and can be Upgraded into Siege Elephants in Castle Age to better stand against defensive buildings such as castles.

Ballista Elephant stats:

* Health: 250/290
* Attack: 30 melee; 30 ranged; Bonus against Siege +90 (Springald)
* Rate of fire: 1.7s melee; 4s ranged;
* Range: 1tiles (tusks), 10 Tiles (Springald)
* Armor: 3/4
* Speed: 0.88 tiles/s

Ballista Elephants are counted as Cavalry, so they suffer the same penalties as cavalry against spears and benefit from the same Cavalry upgrades. This makes them more vulnerable against Ranged units as they don’t have extra range armor, but don’t take bonus damage against anti-siege weapons.


The Khmer are an economy-focused civilization that plays around a lot almost like a city builder. Where Canals play an important role in infrastructure. If you ever played old RTS, such as Warcraft 1, one used to have to build Roads and make space for new Buildings. While Khmer doesn’t necessarily need Canals to be able to build buildings, they provide a beneficial boon to all building types. Khmer was called a Hydraulic state, for the reason that they mastered water and irrigation to an extraordinary level.

Building canals shouldn’t be any more complicated than building walls, only here they have a small radius which any building connect to gets a beneficiary boon and needs to be connected to a Baray. The canals do block unit movement but are rather easy to destroy and do not function well as walls, with low HP pool and no resistance to siege initially.

The canal bridges are also always open for any friendly or opponent units to cross. The Canals themselves would interact pretty much how walls interact with the terrain and are about the size of a stone wall (Imagine somewhat akin to a stonewall foundation), so it does require some planning to construct them optimally.

Elephants also play a huge role in SouthEast Asian culture, and were used heavily as a beast of burden, assisting in Construction works, Quarries, but also more noticeably at Foresty, commonly used to haul logs and bring down trees. Hence I wanted them to be able to tear down trees but at a far more effective rate than a single villager.

This also gives the Khmer a unique trait, allowing them to make paths through forests rather quickly if the opponent relies too heavily on them for defense.

Khmer is a fascinating empire that rose quickly in the early middle ages and disappeared into history leaving some of the magnificent stone structures of mankind, after its slow collapse over the late middle-age. It once boasted the highest population in the world at that point in time, due to the great city of Angkor, and their mastery of the waterworks, which allowed them to quadruply the yield of crops, booming their population. I also wanted to replicate their AoE2 feature where they do not require buildings to age up, in the form of freely choosing between the 6 landmarks to a total of 3. Allowing them some flexibility in their build orders depending on what their planning to go for.

If you liked reading through this, I also made one for the Japanese [Suggestion] AoE4 New Civilization concept: Japanese

Next up: Korea


Cool concept. I would really much like Khmer Empire as a civ. Unfortunately considering the high orientation on e-sport and the slow development speed it is rather utopic to expect new Civs anytime soon :frowning:

Perhaps. It is really hard to tell.

If you are to look at relic history of their strategy game. They are prone to release content with new “civs/factions” or at the very least content.

I actually dont think the attention to e sports is what has them focused away from content on AoE4.
But rather the upcoming CoH3.

Once CoH3 gets released you we might perhaps see more shift in focus back to AoE4 as they have gone through the final pre-release crunches of developtment.

I also think, while all of this is going on. They are working to try figure out the Microsoft Q&A problem.
Where everything has to be approved by Microsoft, slowing them down significantly.

Sure they got server side patches.
But in all realism. Last month major patch is in all honesty probably finished in January. I wont actually be surpriced if new civs are already on their drawing board but we most likely wont see them until upcoming Q4 this year at earliest

If Relic is not doing the development work agreed with Microsoft as required because they are using developers for CoH3, I sincerely hope that Microsoft realizes this and does something about it. Microsoft would have the power to stop this.

That all depends on the contract. Relic has already completed the part of contract of releasing the game.
Production and Maintanance are very often 2 very different contracts. And often they are not obliged to use the Production team for the Maintanance. Because that would also involve putting outsourced-teams in more permanent contracts.

Very often the Production is majority outsourced.
one would at least in the video game industry have such things as the 3D modelling/texturing, Sound Production and Networking outsourced.
While the core engine programming is run by the main team.
Once all the different parts are finished and put together, its handed over to a different team, which then hands it over to yet another team once the production is finished and game has been Released.
Post released, it is then covered by a different part or entirely different contract all together who is suppose to maintain and run the game while its live.
This is a pretty common business practice for pretty much anything.
The people who make the cars are rarely the ones repairing the cars. Even when the car is sent back due to Warranty issues, it is sent to a certified workshop or a workshop owned by the same company, but the guys in charge of finding the fault and repairing it, arent usually the guys who were in the factory making the cars.

Yes it depends on the contract. Hard to believe that Microsoft is satisfied with the decrease in player numbers and the very slow development speed.

The slow development combined with the high focus on e-sport kills this game. If this trend continuous soon Microsoft don’t want to make a DLC for it :frowning:

Many ideas are good.

My opinion :

  • I find very little life for the “Ballista Elephant”. Remembering that the “tower war elephant” (Delhi), have a much higher life and can be easily killed by spearmen.

  • I agree that the “Ballista Elephant” should have less health than the “tower war elephant”, but not values below 500 life. My initial guess would be an average between 660-530 life for the “Ballista Elephant”.

  • Ballista damage from “Ballista Elephant” could be a little lower compared to “springald”. Even because, the “Ballista Elephant” could evolve into double shot and thus deal more damage at the end.

I wanted to be a little reserved with the Ballista elephant, due it being a potential very strong anti-siege unit with no real counter. As it counts as a cavalry unit but with the springald range allowing it to fire from rather safe position and not needing any setup time, allows it to become really effective counter-siege

I know it’s been a while on this topic, but you might want to change the name of the tech that gives Worker Elephants 50% more HP and +15 Ranged Armor because the name “Siege Elephant” is already used for one of the unique techs of the Delhi Sultanate.

This was really well done
