Age of Mythology: The Titans adds a fourth culture, the Atlanteans, to the existing Greek, Egyptian and Norse mythologies. A new single-player campaign will add yet another chapter to the franchise's expansive folklore with the addition of 12 new scenarios. Atlantean players will be able to call upon the might of the Titan gods (such as Atlas and Cronus) multiple times throughout the game, and may also upgrade human units to heroes. The expansion pack will introduce 12 new god powers, 18 new human units and 10 formidable myth units to the game. Age of Mythology: The Titans may also be played with others online using the in-game matchmaking service, ES Online.
