Files with the .SCN extension contain scenario data unique to the Age of Mythology and Age of Empires games – a campaign map, including the terrain, units, player start locations, and victory parameters. They can contain both default content and user-created content.

Age of Mythology is a real-time game in which players participate in campaigns by controlling mythological units and divisions. SCN files can be found in the “scenario” sub-catalog of the game installation catalog. The Age of Mythology scenario creator allows for the creation or editing of custom scenarios.
