Author File Description
File Details
Game Version: AoE3+TWC+TAD
AI 10 - The Horsemaster N3O AI & Flycatcher N3O AI

This version is for N3O Added Pack Patch. It is the Horsemaster AI with the added content from N3O Added Pack. It is not compatible with the original game.

Uses Observatory, Tribal Council's Hut, Aztec Great Temple, New Capitol Upgrades, New Market Upgrades, and builds a little bigger Navy. All players need N3O Added Pack installed to play with the AI.

Not compatible with previous versions of the N3O Fan Patch.

Is used in place of original N3O AI. Plays every civilization.

For general information see original Horsemaster AI for Asian Dynasties:



AI 11 - Flycatcher:

It is a Continuation of Horsemaster, and this one is for N3O Added Pack.

Install if you have N3O Added Pack and want a more updated AI.



- Update August 10-11: Allowed German AI to train Mercenaries and Native Warriors. It also trains more Cavalry Bias, less Uhlans, More War Wagons.

- Added Siege Discipline Card for Iroquois, Thoroughbreds for French, Military Reforms for Dutch.

- Removed Infinite Grenadiers from Britain, and Richelieu's Regiment from French

- Added staggered resources savings for non-Treaty Games.

- AIs gather for 2 Town Centers in Fortress rather than 1.

- Added Handling for Naval Maps, including 20 Fishing Boat boom on water maps, and Transport Handling for NR Caribbean, NR Ceylon, NR Amazonia, NR Honshu and Island Polynesia. Expect naval invasions!

- Portuguese now research Econmedia Manor from Church card.

- British AI now always builds 2 Additional Town Centers.

- Maritime Maps also handled in AI script.

- Added Island Polynesia to Fishing Maps


- Update July 29: Updated Portuguese AI to not use Mercenaries and Ottoman AI to not spam Barbary Corsairs.

- Update July 27: Spanish AI not to use Spanish Square as in Treaty it prevented them getting enough Villagers.

- Made Aztec AI train more Jaguar Prowl Knights, less Coyote Runners.

- Chinese AI fixed training of Banner Armies; it no longer tries to build Light Infantry.

- Update July 23: Updated a fix in the AI to build Capitol always, and skip out on second Market I added previously.

- Update July 19: Aztecs Unit Priorities redefined. I have given Aztecs a Civ Bias of 0.5 BiasInf and 0.5 BiasCav (which also works for Light Infantry), and in addition extra Priorities for the Knight Units first, then War Hut Units second. This means that they will constantly train units while they have resources for them.

- All AIs can now make use of Light Infantry, not just Aztecs.

- AIs now use 10-20 units in training queue rather than 10-25.

- AI uses 85 Military Units in Industrial and 100 in Imperial (up from 80 Industrial, 110 Imperial; original was 70 Industrial, 90 Imperial).

- Aztec AI on account of less units in Imperial now again spawns Skull Knights when there is military population available; Sioux AI should also spawn Dog Soldiers.

- German AI trains more Skirmishers.

- Indians, Chinese, Japanese now have secondary and tertiary btOffenseDefense increased to 0.45 (up from 0.35); the normal value remains 0.50. This should prevent them from camping in their bases until very late game (1 hour).

Flycatcher AI:

- Update 3 July 2021: 2 Building Unit Training once again.

- Update 2 July 2021: Military Units trained from 1 Building instead of 2 at a time, like in AI 9 - Big Daddy.

- Update 1 July 2021: Extra Market built in Imperial Age by Asians rather than Industrial; this should help Wonder Age ups to Imperial. It is still built in Industrial by Europeans and Natives.


Things Different in AI:

- Rice Paddies can be build 5 distance (down from 8). Asians try to get an additional Rice Paddy in Imperial (up to 5).

- Maximum Army Unit count increased to 80 for Industrial (70) and 110 for Imperial (90).

- German AI trains more Dopplesoldners, Uhlans, less War Wagons and less Mercenaries, same amount of Skirmishers

- Japanese AI no longer tries to train Arsonists or Flaming Arrow Artillery (Arsonists are not classified as Mercenaries).

- AIs for Ottoman, Dutch, British, French, Spanish, Portuguese, German, Russians, have been made more aggressive (0.45, 0.50, 0.55)

- Turtle Up Rule increased to +0.8 so that Civs can eventually receive increased OffenseDefense while still being able to build walls and towers (up from +0.6).


- Final Update 27 April 2021: French AI trains original values.

- Update 19 April 2021: Native American Civs have their bonus Handicap for Treaty reduced back to 1.50 (was 1.65). This allows for Expert AIs to play online, even with people who don't have AI installed. Host has to put it at Expert however (This is because Baseline Handicap is different in Basic AI, AImain.xs for Asian Dynasties). The N3O Patch though is compatible with LAN rather than online, where you might get errors.

- Update 17 April 2021: French AI now trains the old core of Troops, but prioritizes Cuirassiers, Dragoons, Hussars and Skirmishers more.

- Update 13 April 2021: French AI now trains a Napoleonic Core of Troops: Musketeers, Skirmishers, Cuirassiers, Hussars, Dragoons. This allows them to counter cost-effectively. French AI also uses Richeleiu's Regiment instead of 4 Infinite Cuirassiers.

- Update 12 April 2021: German AI priorities returned to original (0.4 Cav, 0.6 Inf, 0.0 Art, from 0.4 Cav, 0.7 Inf, 0.1 Art).

- Update 11 April 2021: Wonders, Castles and Town Centers now place with 1.0 spacing (up from 0.0). This is to make the AI move troops easier through its base. Added also 1/8th of villager count to Fire Pit Dancers (was 1/7).

- Iroquois use Onondaga Support rather than Seneca Support (14 Tomahawks +5 Crates of Wood instead of 10 Forest Prowlers +2 Travois).

- Update 1 April 2021: Russian Units returned to Normal/Original, Bias Cav returned to 0.2 (0.5). (This was because I tried a value which didn't make them train many units.)

- Update 28 March 2021: In Treaty, AIs will now focus on 95 Economic Population, and less for French (85), Dutch (75), Japanese (85); 220 Population except for 240 for Chinese. Sioux now can correctly research Strong/Mighty War Hut. Bonus Handicap for Natives in Treaty brought down to 1.40 for Hard, 1.65 for Expert.

- Ottomans correctly build extra Town Centers on regular maps (I had tried a condition that didn't work)

- Spanish Units returned to Normal (I had tried values which didn't work for training units)

- Update 26 March 2021: Aztecs train better military; No Aztec Mining. Ottomans use Spahi Shipments rather than Grenadiers. Better handling for Infinite Shipments added. Factories are on Gold/Food/Wood until Imperial, then they switch back to Gold/Cannon/Cannon. Russians always upgrade Bastion. Iroquois and Sioux always upgrade Strong/Mighty War Huts. Bonus Forecasts of 2500 food added for Imperial Age. Better Handling for Industrial Age unit Shipments added. Added Handling for Distributivism, Colbertism, Capitalism. Bonus Handicap for Treaty brought back to 1.25 for Hard, 1.15 for Moderate, 1.0 for Easy, 1.5 for Expert (Natives still have 1.5, 1.25, 1.15, 1.75). Russian/Spanish AI slightly updated.

- Update 23 March 2021: Shrines, Houses for India, and Mango Groves all have 1.0 placing (down from 3.0). Simple build plan radius increased from 50 around the town to 100. Japan Builds its two extra stables in Industrial Age rather than Fortress.

- Update 21 March 2021: Wonders, Town Centers, Castles and Factories all can be built next to other buildings without extra spacing. This should help the AI age up with the Asians to Imperial Age and help tight-bases for Europeans. Simple build plan radius increased from 30 around the town to 50.

- Update 20 March 2021: Ottoman AI now builds extra Town Centers in regular matches. Handling for Pioneers moved to Imperial Age.

- Russian AI builds old units, but also uses Boyars Shipment. This AI also focuses more on Cavalry: Cossacks and Cavalry Archers.

- Target Settler Counts increased to 80 in Colonial Age and 90 in Fortress (up from 50, 85)

- Native AIs have higher Handicap Bonus for Treaty Games than other AIs (1.25, 1.35, 1.50, 1.75).

- Aztecs now dance for Warrior Priests at the dance pit (up to 4). All Native AIs use 1/7 of their Villagers on the Dance pit rather than 1/6.

- Ottoman AI researches Topkaki earlier in the game (25 villagers rather than 33 villagers). Increased normal btOffenseDefense to 0.45.

- Update 19 March 2021: Factory Cannery and Factory Water Power are upgraded by the AI. Easy, Moderate, Hard, and Expert now have a separate bonus handicap for Treaty Games: 1.0 for Easy, 1.25 for Moderate, 1.35 for Hard, 1.60 for Expert. Hard brought back up to 90 economic population; Moderate has 180 total population, and Hard and Expert use 99 Villagers with Natives. Easy uses 80 villager population as Natives, Moderate uses 90 (75 and 80 for other Civs).

- Update 18 March 2021: Easy and Moderate have +10 Population on Treaty Games (80, 160; 90, 190), Hard has 5 less economic population on Treaty Games (85). AI's now build 2-3 extra Town Centers in Fortress if they can and have less than two Covered Wagons available.

- Spanish, Portuguese, and Russian AIs improved; Spain builds Hussars, Musketeers, Skirmishers, Lancers and Rodeleros; Portugal builds more Infantry/Cavalry, Russia builds more Cavalry Archers, balanced amount of Infantry, and Cossacks.

- Infinite Grenadiers, Infinite Cavalry Archers, Infinite Musketeers included; Handling for Industrial Age Units Shipments added if included in deck.

- Native Villagers and Asian Villagers can build Town Centers for the AI.

- European Factories produce food/coin/wood if there are 2 to 3 of them. This is instead of Cannons, which they often don't have the population for.

- Update 15 March 2021: AI Main updated: Aztec AI builds Coyote Runners, Eagle Runner Knights, Macehualtins, Jaguar Prowl Knights, Puma Spearmen, but very few Arrow Knights.

- Aztec AI uses Aztec Mining and 1000 Infinite Coin Card on high homecity levels (100 and above). Iroquois use Pioneers Card, and Seneca Support (10 Forest Prowlers +2 Travois). Handling added for Aztec Mining, 1000 Infinite Coin, Pioneers Cards. Grain Market Card (+20% Mills) will ship earlier than before for Aztecs. AI chooses 15 Special Cards (up from 14).

- Update 13 March 2021: AI Main updated: Chinese AI uses Refugee & Migrant Shipments which give Villagers and also Covered Wagon Shipments at the right time in the game. This should give them a large advantage in games where they previously sent villager shipments too late.

- Update 10 March 2021: AI Main updated: Iroquois AI Builds one more War Hut and Sioux AI builds two more War Huts. Additional Fort Wagons are better used now, and should not interfere with initial forward base, and the AI can use Outpost Wagons to build Blockhouses. Natives & Asians now put Factories, if they have any, on Food/Coin/Wood rather instead of trying to build Heavy Cannons.

- Update 9 March 2021: AI Main updated: AI now builds two Town Centers in Fortress, Three in Industrial. Moderate AI uses 85 economic pop, and has 1.0 handicap (up from 0.90). The Extra two Mills are built before the extra two Plantations. Germans build one mill in Fortress always. 1500 food/1500 coin added for treaty non-spending escrows. Russians also train less priority to Ranged Infantry, thereby a balanced army like in earlier versions of Horsemaster AI (0.93, instead of 0.935).


This AI builds mostly same as AI 9 - Big Daddy: It is a work in progress.

It trains four unit types at a time. The point of making this AI is to improve it gradually over time, and release and re-release new versions of it.

In the Horsemaster, I have tried to fix the small errors that I did with the previous Big Daddy: Dutch not always building Units, Slow-training for Iroquois, and the Cavalry-only army for India.

AI is still primarily a Deathmatch AI. Custom maps such as Legend Maps are good for testing purposes on Discovery Age starts.

Native American AIs use War Dance when they have large armies, and XP Dance as default dance (instead of War Song which spawns Dog Soldiers). Sioux and Aztecs dance for Dog Soldiers and Skull Knights.

The Expert AI got 1900 score on African Guinea on 20 minute treaty as the British.

I got some 2000+ score by that time as India on N3O Added Pack.

In a little while, I will do some testing for Aztec and German AIs with the recent updates to the Flycatcher, and add them to this one. Be patient as the work goes on!
