Age of Empires Series Wiki

The Forgotten Empires mod trailer introduction.

Age of Empires II: The Forgotten (informally abbreviated to AoF) is the second official expansion pack for Age of Empires II. It features five new civilizations, (the Incas, Indians, Italians, Magyars, and Slavs), new units and technologies, new maps, enhanced AI, a higher population limit, greater on-screen rendering, bug fixes and several tweaks to old units, technologies, and bonuses for improved gameplay balance.

Originating as a fan-made modification (before they became Forgotten Empires Studios) entitled Age of Empires II: The Forgotten Empires, the expansion was developed with SkyBox Labs and released in 2013 exclusively on Steam. It requires the Age of Empires II HD Edition for installation.


The Forgotten includes seven new campaigns. Those are:

  • Alaric (Goths): The trauma of the Hun invasion in the 4th century has shaped Alaric, the fearsome warrior king of the Goths. But can the beloved king secure a new homeland for his people in the territory of the collapsing Roman Empire?
  • Sforza (Italians): Always hungry for glory and wealth, Sforza wanders around 15th century Italy, offering his services to the highest bidder. Will he pick the right battles or make the wrong enemy? Take the fate of the young mercenary captain in your hands.
  • Bari (Byzantines): 400 years after the collapse of the Roman Empire, Italy is still up for grabs. Relive the tale of the port city Bari from the point of view of a Byzantine family, rising from the common soldiery to the nobility. Beware, for not only Bari is at stake, but also control of Southern Italy.
  • Dracula (Magyars, Slavs, Turks): History forged an incredible legend around the man who ruled Wallachia in the mid-15th century. Holding his ground against the vast armies of the expanding Ottoman Empire, his cruel tactics made him the most feared man in all of Eastern Europe. Shall his thirst for blood and the loyalty of his soldiers hold the Turks back for good?
  • El Dorado (Incas, Spanish): Join Francisco Orellana and Gonzalo Pizarro on their quest to find El Dorado, the legendary Lost City of Gold, thought to be hidden somewhere in the vast Amazon rainforest. Will their quest along the Amazon River lead to lifelong prosperity?
    This campaign was added in the patch released in March 4, 2014, featuring the Spanish conquistadors in their search for El Dorado in South America.
  • Prithviraj (Indians): As the 12th century comes to a close, India is divided between the ruling Rajput clans. One of them, the Chauhans, have just been blessed with a new king. His name is Prithviraj and his determination to unite the rival states is unprecedented.
    But what happens when he falls in love with the daughter of his enemy? And does he have the strength to stop a full-scale Muslim invasion from the west?

    It was added in the 3.5 patch, featuring the Indians in medieval times. Prithiviraj is the king of one Rajput clan and your mission is to unify the Rajputs.
  • Battles of the Forgotten (various): Time has faded the names of many of the greatest leaders ever known. During their age they were famed for their fierceness on the battlefield, their just rule and their quest for power. Witness the path to glory of Richard the Lionheart, Minamoto no Yoritomo, Sultan Osman Ghazi, Khosrau and many more.
    Added in patch 3.6.

  • Italians: The various cities of Italy were the sites of much technological, artistic, and military achievement during the Middle Ages. They are an archer and naval civilization, with the Genoese Crossbowman as their unique unit. They and their allies can also train Condottieri at their Barracks.
  • Slavs: They represent Eastern Slavic nations like Novgorod or Kievan Rus. The Slavs are an infantry/siege civilization and their unique unit is the Boyar.

Scenario Editor units[]



  • In The Forgotten, every civilization (except the Goths, as they have access to their two unique technologies in The Conquerors) has two unique technologies: one in the Castle Age, and one in the Imperial Age. Both must be researched at the Castle.

General technologies[]

Unique technologies[]

New random maps[]

  • Cenotes: Open rushing map (Arabia style) with a standard set of resources. Small lakes are scattered around all over the map and provide little fish.
  • City of Lakes: Semi-closed water map. Galley rushing can prove fatal on the wrong lake, and fishing on the right one can mean a great boost for your economy. Rather easy to wall, but transports are possible from all sides.
  • Hideout: Players start in their little hideout camp in the forest. You'll have to break free to conquer your foes.
  • Budapest: A spiced up version of your everyday map, starting with two Town Centers.
  • Steppe: Nomadic map; players start out with a few yurts and 3 extra villagers. There is an abundance of hunt wanders on the plains in the center of the map.
  • Valley: Semi-open map. A dried up river runs through the middle, with herds of deer trying to drink from the last puddles that run along the sandy shore. If you want to hunt, you'll have to go there. But you won't be alone…
  • Hill Fort: Fortress type map; players start on a hill together with their teammates. Can you take over your opponents hill, or will they make it impenetrable?
  • Lombardia: Open map; players start clumped together with their teammates. Good coordination between teammates seems more vital than ever to rule these Northern Italian lands. Divide et Impera!
  • Acropolis: Extremely open map; players start on a hill that is impossible to wall. They must come off their hill to gather resources in the carnage below. They say of the Acropolis where the Parthenon is…
  • Golden Pit: Variation of Gold Rush. A pit in the center of the map contains large mining reserves. However, protecting the pit means you have to fight uphill. Hill advantage or gold to spend, the choice is yours to make (Incredible map for FFA – Free For All games).
  • MegaRandom: It can be anything!

Other features[]

  • Two new game modes: "Capture the Relic" and "Treaty".
  • New size of map "LudiKRIS".
  • Population limit of 500 (The Forgotten Empires mod had up to 1000).
  • Improved AI, the player can choose between Promiskuitiv's enhanced AI (new default 'Computer') or manually select the old 'Conquerors AI' (Petersen AI).


The introduction of The Forgotten came with a host of changes to the game, with the game version being incremented from 2.8 to 3.0. Some of the changes included in this new game version affect only those in possession of the expansion (content additions and balance changes) while others (bugfixes and UI improvements) affect all players equally; the former are included in the official patch notes of version 3.0 linked in the infobox.

Bug Fixes, Performance and UI Improvements[]

General Gameplay[]

  • Attack-move: There is a new button and hotkey for this. Units will automatically engage enemy units while advancing to their destination.
  • Balanced Build Queue: When you select multiple buildings, all units created are load balanced for quickest completion time.
  • Scrolling has several improvements. Diagonal speeds match horizontal/vertical speeds. Also the diagonal angle of scrolling matches the tiles (perfectly parallel to the map edge).
  • The AI has remembered that trebuchets are useful in battle! Be prepared to counter siege units again
  • Game Speed - You may now choose to go up to 8X speed via the hotkeys in single player (Number pad + and number pad - )

System Improvements[]

  • Registry settings are now centralized for game options. In the original code base, they were controlled and maintained in an adhoc manner and some didn’t update until you exited the game without crashing.
  • Game Settings are remembered instantly. The cancel button has been removed. All game settings are enabled by default (and some have been renamed to allow the most common settings to be enabled).
  • Sound volume has been renamed to Master volume, to better reflect its functionality, as music volume is relative to master volume.
  • Music comes back after losing focus.
  • Scroll speed has been rebalanced again (so you will want to readjust).
  • Player profiles have been rewritten and should no longer be corruptible. For most players, it will port your campaign progress to the new profile system, but other settings for recent singleplayer and multiplayer settings will be started fresh.
  • Player profiles now immediately remember settings for all modes:
    • Single player settings in Age of Empires: HD Edition (referred to as AoK for simplicity for the items in this list)
    • Multiplayer settings in AoK
    • Single player settings in Age of Empires: The Forgotten (AoF)
    • Multiplayer settings in AoF
    • Lobby filter settings
    • There are a few setting exceptions that aren’t remembered where it makes sense. For example, in MP, locked teams will always be enabled by default.
  • All languages now use text files instead of dll files. Enterprising individuals should easily be able to take the English strings and translate them to any language of their choosing and share them in the workshop…like ewok!
  • Cursors are now a consistent size (some cursors were showing up too small).
  • The games extension system has been rewritten to allow for separation between features only available in Age of Empires: HD Edition (AoK) and Age of Empires: The Forgotten (AoF):
      • .ai, * .ai2: These files are generally blank, exist in the AI folder and declare AI personalities of a matching name. AoF can load both types. AoK can only load * .ai files.
      • .per, * .per2: The counterpart to * .ai and * .ai2 files. These files also live in the AI folder and contain all the scripting support for a personality. AoF can load both types. AoK can only load * .per files.
      • .rms, * .rms2: Random Map Script files that live in the Random folder. AoF can load both types. AoK can only load * .rms files.
      • .gax, * .gax2: These are single player save game files and are mutually exclusive. In AoK you can only save and load * .gax files. In AoF, you can only save and load * .gax2 files.
      • .msx, * .msx2: These are multiplayer saves and are mutually exclusive. In AoK you can only save and load * .msx files. In AoF, you can only save and load * .msx2 files. (ditto with * .tmsx, * .tmsx2 – which are temp saves).
      • .mgx, * .mgx2: These are replay files and are mutually exclusive. In AoK you can only save and load * .mgx files. In AoF, you can only save and load * .mgx2 files.
      • .scx, * scx2: These are scenario files. AoF can load both types. AoK can only load * .scx files.
      • .cpx, * .cpx2: These are campaign files. AoF can load both types. AoK can only load * .cpx files.

Performance Improvements[]

  • The AI has been optimized to reduce how often it searches for targets when it doesn’t have one. This was responsible for approximately 10% or more of the frame rate cost and should improve late-game performance.
  • Left+click dragging (selection boxes) no longer negatively affect the frame rate while the mouse is moving.
  • Moving the mouse while placing a building no longer negatively affects frame rate.
  • Many of the sprites (buildings and units) have been optimized to use less draw calls.
  • Frame rate now follows new constraints that eliminate most types of “command-lag”. For more details you can view the Public Performance Beta notes[http//Public+Performance+Beta+notes].

Scenario Editor[]

  • The player can now generate maps in the Scenario Editor with RMS files inside your Random directory as well as any of the embedded random map types.
  • The player can now paint any terrain type.
  • The player can now use any terrain type when setting the base terrain.

Multiplayer Features[]

  • Mirror Random has been added to civ dropdowns in multiplayer. When you choose this option, you civ will be chosen from the civs on the opposing team. The rules are a little more complicated in how selection works to account for all cases of course 


There was a small hotfix addressing some minor bugs associated with the release of this patch:

  • Loc displaying issues in languages other than English. (No Chinese did not start with an Eagle Scout).
  • Capture the Relic - ensuring Monastery was invulnerable for a few specific edge cases
  • Game speed options in UI functions properly when selecting. Players can still use num+ / - to go up to 8x in single player.


Although there are no official reviews, Age of Empires II HD was well-received by the Steam community, where it has a rating of 9/10.

Most reviews praised the 5 new civilizations, new technologies, fixes, random maps and the design of the campaigns (eyecandy) and some of its content.

However, the new AI and campaigns content were considered "bad", with the AI being called "dumbed down" and not as good as the Conquerors' AI. The campaigns were attacked for leaving the build and destroy style, for a "Fixed Force" or "Regicide with a Hero" (used in many fanmade scenarios) along with units being stuck in eyecandy, being too hard, and "not allowing you to play/unskippable cutscenes".
