The bold, honorable Tupi prowl the eastern jungles, escarpments, and coasts of South America with formidable warbands of infantry and ranged soldiers. Wide geographical distribution grants them easy access to a variety of resources, while prudent frugality promotes sustainable use of arms and armaments. As foreign arrivals reshape the internal and external tribal relations, the Tupi trust in their large numbers and skilled diplomacy to endure whatever adversity comes their way.

Unique Units

Blackwood Archer

Tupi bows were usually made with blackwood and were larger than traditional European bows. The Tupi sometimes made flaming arrows by tying cotton to an arrowhead, dipping it in wax, and then igniting it. They also created poison arrows by using stingray spines as arrowheads.

Blackwood Archers are inexpensive and train in pairs, allowing armies of them to be fielded extremely quickly.

Ibirapema Warrior

While Tupi bows were multifaceted weapons, the ibirapema was imbued with ceremonial significance. It was decorated with feathers and colorful paint, and used in ritual killings of enemies. The Tupi also deployed ibirapemas in close combat situations.

These hulking heavy infantry units swing a massive club at enemies, dealing area damage.

Unique Technologies

Caciques

The cacique was the chieftain of an indigenous tribe. These charismatic leaders boosted the morale of their warriors and took charge of their tactical movements on the battlefield.

Effect: Champi Warriors and Slingers attack faster.

Curare

Curare is a plant-based poison historically used to tip weapons and projectiles throughout much of Central and South America. Depending on quantity and concentration, the poison can cause weakness, local paralysis, and even asphyxiation.

Effect: Foot archers and fortifications deal poison damage over time.

Moodboard for the Last Chieftains

When we started designing the South American architecture set, the focus was mainly on Inca ruins. For the most part, that stayed true. But early on, we decided to broaden the scope to include the rich traditions of the Mapuche, Muisca, and Tupi peoples, drawing inspiration from their every day structures like the ruka, bohío, and oca.
You’ll see these influences not just in the unique castles and wonders, but throughout the Feudal Age set. Everything is grounded in authentic sources, including contemporary architecture, historical accounts, and woodcuts.
Inca polygonal masonry, advanced hydraulic engineering, gold-plated surfaces, and the distinctive absence of intersecting roofs all guided the design of the Castle and Imperial Age buildings. The fortress of Sacsayhuamán played a big role in shaping fortified walls and universities. And yes, even the Feudal mill hides a little Nazca-inspired twist with spiral wells beneath it.

Once the concept art was ready, it was time to translate those sketches into 3D models. That’s where Chris, Anka, and Inma worked their magic, creating everything from buildings and animals to heroes and units.

Pilot Model of the Imperial Age Town Center

I kicked things off by creating the pilot models for the Andean set, serving as the benchmark for the rest of the team. One of the biggest challenges was getting the 3D thatch to look right. The automatic shadowing system in the game tends to make dense areas look too dark. We had to put in extra effort to fine-tune the lighting and shadows so the roof texture looked just right.

Another tricky part was the gold ornaments. To make them really shine and stand out, we added an extra light source that only affects those details, giving them that rich golden glow.

Regular Blackwood Archer

For the new South American-themed units, I started with the concept art and built the 3D models from the ground up. I focused on capturing the ornate jewelry and distinct shapes for the humanoid units, and tackled the challenging task of digitally sculpting the unique features of the Spanish War Dog. The hardest part was finding the perfect balance between historical authenticity and the stylized proportions required by the game’s art style. Despite the challenge, it was incredibly satisfying to translate those cultural details into three dimensions and see the characters finally come to life.

It was a breath of fresh air to work on these units and buildings because they are so different from what we have done in previous DLCs. During the modeling process, we have to carefully balance the amount of detail with what the player will actually see on screen. Since units in Age of Empires appear quite small, we must exaggerate the proportions of key features, like weapons, to ensure they are visible.

The toughest part of this balancing act is often cloth wrinkles. To be visible in-game and look aesthetically pleasing, clothing wrinkles almost always have to be exaggerated and made much larger than they would be in real life.

Latauro – Campaign Hero

With the models finished, the next step was animation. Nebeolise and Rajun, our animators, shared their insights.

When starting on animations, we always first dive deep into the cultures and history to make sure every movement of the unit feels authentic.

Take the Ibirapema Warrior for example. To animate them properly, we need to understand their role in society and their warrior tactics. Even something as simple as defining an idle pose depends heavily on their traditions and weapons. Furthermore since they wield a really heavy club, we had to ensure that the weight and power were visible in its swings.

The core difficulty in creating destruction animations for buildings is figuring out how a structure will collapse naturally while staying within its own footprint and not having debris fall outside of it. A big source of inspiration for this is controlled building demolitions in real life.

Since these animations involve simulation work, the biggest difficulty is optimization. A thatched roof with millions of polygons can lead to extremely long wait times and even crashes from overloading RAM so we had to think of ways to optimize these.

Imperial Age Town Center

With all the 3D models and animations created, it was time to make them shine in-game. Enrique, our Art Lead, talked about how they made the assets look great in the final render.

Feudal Age Building Set

We spent a lot of time refining the look of the set for each age. Our goal was to stay as historically authentic as possible, while also adapting the designs to the Age of Empires II style. That means colorful and vibrant, yet still believable, so everything feels cohesive with the other architectural sets.

It also helps players quickly recognize age progression in buildings and understand roles and tiers for units. This readability is especially important because of their small size at the standard zoom level.

Champi Warrior

Selecting the colors usually starts during the concept phase. Once the model is complete, we adjust materials to account for lighting and shadows in the final render. Sometimes what looks great in concept doesn’t translate well in the render, so we iterate until it feels right.

For units, there is an extra validation step when we test the default pose. If important details are hidden or barely visible, we tweak the materials or adjust the design to make sure everything remains clear.

Bringing a completely new architectural set, unit roster, heroes, animals, and flora to Age of Empires II: Definitive Edition has been an immersive and challenging journey for the team. We approached this project with respect for the original art direction and a deep commitment to honoring the cultural legacy of these civilizations. We hope you enjoy playing The Last Chieftains as much as we enjoyed creating it.
