Airborne Units is a third type of units in Age of Mythology and Age of Empires III after land units and ships. Flying units are much more rarely seen, and it is by no means certain any will appear in a given game. The main advantage of flying units is that they are not constrained by any obstacles on the map. They can fly over land, sea, rocks and walls, exploring every corner of the map. Additionally, they can only be attacked by ranged units (including, in some cases, other flying units.)
In Age of Empires and Age of Empires II, the only flying units to appear are the occasional birds added for atmosphere. They are purely ornamental and cannot be interacted with in any way. (There is also the Flying Dutchman cheat unit in Age of Empires, which, though a flying unit, could still be attacked by melee units).
Age of Mythology Edit
The Greeks only have the Pegasus, a scout trainable for all three major gods, from the Temple in the Archaic Age. The Pegasus can be obtained as a respawning unit by all Civilizations with the Relic Bridle Of Pegasus.
The Egyptians have the Roc, a large flying unit that cannot attack, but instead can transport units, taking them over sea, rock and enemy walls. It is trainable by Ra and Isis through worship of Hathor. They also have the Phoenix, a battle unit that breathes fire, and can respawn from an egg if killed, trainable by Isis and Set through worship of Thoth.
The Norse have two units, the Raven (Odin only), a respawning scout unit that cannot attack, and the Nidhogg, a powerful dragon, that can be summoned by Hel's God Power, available only to Loki. The Nidhogg is the strongest regular flying unit in the game by far.
The Atlanteans have the Caladria, a flying healer that cannot attack, available through worship of Oceanus in the Classical Age as Oranos or Gaia, and the Stymphalian Bird, a flying bird that shoots bronze feathers at foes, available for Oranos and Gaia as well, through worship of Theia in the Heroic Age.
Kronos does not have access to airborne units.
Other than that, the Servant of Kronos appears in the campaign, but cannot be controlled by the player, if not using the scenario editor. If the
WUV WOO Cheat Code is used, the player obtains the Flying Purple Hippo Cheat Unit.
Age of Empires III Edit
Only two flying units appear in Age of Empires III, both exclusively scouts: the Hot Air Balloon and the Advanced Hot Air Balloon. The ability to create them is obtained from a Home City Card in the Colonial Age for all European civilizations. It grants the Explorer the ability to set a hot air balloon anywhere on the map, where it can explore until it dies. The Advanced Hot Air Balloon is a single use unit, available with one per game, that does not die after some time. These balloons can only be killed through direct targeting of them, meaning AI players cannot take them down.
