Spoiler warning: This article contains information on a Cheat Unit. Please use discretion when viewing this page.
A Medusa is a Villager-like unit available in the original Age of Empires. It qualifies as a Cheat Unit and is also available in the scenario editor as well as the campaign mode of the game. To activate the cheat code, press ENTER and type in MEDUSA. All villagers on the field of play that belong to you turn into medusas. Villagers you convert after the activation, however, remain villagers.
Being a military unit, Medusas do not benefit from technologies such as Jihad that would otherwise affect Villagers. The unit has a special ability for being able to reincarnate twice. When it dies, a Medusa turns into a Black Rider. When the black rider dies, it turns into a Catapult, Heavy Catapult, or Big Bertha. When that unit is killed, it is gone for good.
