Walls of Constantinople is the third scenario in the Attila the Hun campaign in Age of Empires II: The Conquerors. It is loosely based on Attila's third Balkan campaign of 447 A.D., which climaxed with the Battle of the Utus.
- Starting Age: Castle Age
- Starting resources: 1,000 wood, 1,000 food, 1,200 gold, 200 stone
- Population limit: 75
- Starting units:
- Stockpile 10,000 gold in tribute from the Romans.
- Although your goal is to collect gold, do not worry about spending it to train troops. Huns make money by extorting the Romans, not by conservation!
- Destroying Roman Town Centers, Docks, Markets and similar buildings will scare the Romans into paying up. But despite their protests, do not cease until you have 10,000 gold.
- You cannot merely trade resources for the gold you needed. Your objective is to exact a tribute from the Romans.
- The Huns may not go to the Imperial Age.
- Your scouts report: The Huns (yellow) have a small town that they will need to defend against early attacks from Marcianopolis (green).
- Marcianopolis does not have a strong army, but their town is walled, which can prevent an early Hunnic attack. Once you breach the gates, however, the town should crumble.
- Phillippopolis (red) is defended only by a few towers initially, but they will train an army of infantry and Light Cavalry.
- Constantinople (blue) is by far the greatest threat. The city's famous walls are very hard to siege but it is not necessary to do so. Extort money from the Romans, and you will be victorious.
- Player (Huns): The player starts in the northern part of the map with a Town Center, Barracks, Stable, Blacksmith, and Mill.
- Constantinople (Byzantines): Constantinople is a big city in the east that is practically impossible to conquer. It is heavily fortified on both land and sea. They do not actively attack the player and are best left alone.
- Marcianopolis (Goths): Marcianopolis is located right east of the player's base. They attack early on, mostly using Men-at-Arms. Destroying their Town Center makes them resign.
- Philippopolis (Byzantines): Philippopolis lies in the west. Destroying their Town Center also forces them to resign. They field Archers.
Attila's army must collect 10000 gold tribute from the Romans. He does this by threatening the Roman cities of Constantinople (blue), Marcianopolis (green), and Philippopolis (red). Attacking buildings such as Markets and Docks is the easiest way to earn gold, although complete destruction of a city will earn even more. This can also be done by building the first Castle, collecting Relics scattered around, trading with Docks (Marcianopolis is fairly weak but has two Docks), or mining the Gold Mines south of Constantinople. The Huns cannot build Markets in this scenario. Contrary to what the scenario hints tell the player, they only need to accumulate the 10,000 gold by any means to achieve victory, it does not all have to come as tribute from the Romans.
With the starting resources start training Knights immediately. Optionally an Archery Range can be built to create Cavalry Archers. Immediately start counterattacking Marcianopolis. Get a siege workshop up to create Rams to level the town of Marcianopolis. Side-by-side, maintaining a strong economy is crucial. Stone is found outside Philippopolis, while there is gold on the outskirts of Constantinople.
Use the gold gathered in tributes from flattening Marcianopolis to train re-enforcements and march on Philippopolis. Use Cavalry Archers and Knights (or Light Cavalry to save on gold) to take out human units and rams for towers and Town Centers. Once Philippopolis is defeated, send in two Monks to secure the relics. There's a Monastery on the outskirts of Constantinople which can be razed for a tribute.
While the hints and dialogue strongly advice against attacking Constantinople, it is entirely possible to defeat them with some patience. Build a Castle right outside the town's entrance. Lure the Crossbowmen, Monks and Onagers guarding the outer periphery of the town with Cavalry Archers. Once they are dealt with, send in rams against the gates and towers. Once the town is breached, start luring the Catapharacts and Monks which are no match for massed Cavalry Archers. Use Rams to get the Castle followed by the Wonder. This should net the player a large enough tribute to win the scenario.
Means to loot resources
The Huns may loot gold and other resources in a variety of ways that are not obvious:
- Every Dock (outside Constantinople) razed provides 500 gold.
- Every Market (outside Constantinople) razed provides 500 gold.
- The Northern Dock in Constantinople when razed provides 1,000 gold in tribute.
- Both the Southern Docks in Constantinople when razed also provide 2,500 gold in tribute.
- Every Town Center razed provides 3,000 gold.
- The first Castle being built will result in a 500 gold offering from the Romans.
- Destroying the Trade Cart that travels between the Philippopolis and Constantinople will result in 500 gold tribute.
- Destroying all the Trade Cogs owned by Constantinople provides 500 gold in tribute.
- Razing the Monastery outside Constantinople will provide 1,000 food.
- Stationing troops around the Wonder in Constantinople will provide a 1,000 gold tribute to dissuade the Huns from razing it to the ground.
- Razing the Wonder in Constantinople will provide 5,000 gold in loot.
- Marcianopolis and Philippopolis are the contemporary Bulgarian cities of Devnya and Plovdiv. The hills of the latter can be made out on the map.
- Marcianopolis was the headquarters of the Roman army that was defeated at the Utus, and it was itself destroyed by the Huns in the aftermath of the battle. Philippopolis, however, had already fallen to the Huns during the previous campaign of 443 - 445 A.D., which is depicted in The Great Ride.
- Marcianopolis is possibly depicted as Goths rather than Byzantines because the leader of the Roman army at the Utus, the magister millitum Arnegisclus, was a Goth.
- An apparent anachronism in this scenario is the presence of the Byzantine Wonder in Constantinople, Hagia Sophia, which was built in 537 A.D. However, a basilica stood in the same place between 415 and 532, when it was destroyed by fire.
- Constantinople was actually spared destruction because it hastily built its outer double walls and Sea Wall in just two months, after the older wall was coincidentally damaged by an earthquake.
- After their victory at the Utus, Attila was able to raid as far south as Thermopylae, in central Greece.
