Age of Empires II HD: The Forgotten (informally abbreviated to AoF) is the second official expansion pack for Age of Empires II, and the first for Age of Empires II: HD Edition. It features five new civilizations like The Conquerors, four campaigns (with three planned to be added later), 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. It was released along with patch 3.0.

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

UniqueTechCastle-DE Castle Age
UniqueTechImperialDE Imperial Age


  • CampaignIcon-AlaricDE 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?
  • CampaignIcon-SforzaDE 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.
  • CampaignIcon-BariDE 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.
  • CampaignIcon-DraculaDE Vlad Dracula (Magyars, Slavs): 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.

Witness the path to glory of Richard the Lionheart, Minamoto no Yoritomo, Sultan Osman Ghazi, Khosrau and many more.

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!

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".

Another criticism for this expansion is that some civilizations were too broad, so the Indians were split into four civilizations in Dynasties of India, the Slavs' umbrella civilization was accompanied with Bulgarians, Bohemians, and Poles in the Definitive Edition, and Sicilians were derived from Italians.
