Age of Empires II HD: The Forgotten

Exclusive to the HD Edition of the game available on Steam, The Forgotten originated as an unofficial modification for the game known as Forgotten Empires.

The expansion pack is being developed by the team that created the mod with the assistance of Skybox Labs, based in Vancouver.

The Forgotten introduces five new civilizations (the Italians, Indians, Slavs, Magyars, and Incas), six new campaigns, new units, new technologies, new gameplay modes, new maps, improved AI and other tweaks to gameplay.
