Limited Time Offer Includes:

Skirmish Booster Pack: Create your own battles! The fully configurable Skirmish Booster Pack allows you to choose every element of gameplay, from resources, teams, and victory conditions to opponent civilizations, difficulty, and strategy. Supports 4-player co-op against up to 4 computer-controlled opponents on more than 20 different maps. Earn new Advisors, vanity trophies, and gear. This feature is available for all current and future civilizations.

Defense of Crete Booster Pack: Pack up your army and head to Crete! King Minos needs your help to defend his island from invaders-and he's sure to enrich your coffers if you succeed. Beat back waves of relentless invaders as you protect the sacred Minoan Wonders from being destroyed. For even more fun, invite a friend to team up against the barbarian attackers. Earn new gear and awesome rewards for defending Crete!

Fertile Crescent Booster Pack: Looking for more quests? The Fertile Crescent Booster offers 30 all-new quests for level 20 cities and beyond. Located in the fertile plain lands between the Tigris and Euphrates rivers and ruled by King Nebuchadnezzar II, Mesopotamia is often considered the cradle of civilization with its advanced irrigation systems and written laws known as Hammurabi's Code. But a code of law is only effective if it can be enforced, and the Mad Median's raiders refuse to follow the rules. It's up to you to prove that the Mad Median and his raiders are not above Hammurabi's Code-or fist. You must protect the crown jewels: Babylon and her queen.

Northern Invasion Booster Pack: Looking for even more quests? The Northern Invasion Booster offers over 25 all-new quests for level 20 cities and beyond, plus a heaping dose of repeatable quests and mini-games with valuable rewards all the way to level 40. In the ancient world, the most northern lands of Europe were a frontier inhabited by a wide variety of people including the Norse, the Teutons, the Celts, and other ancient Germanic tribes. Climate change due to a "Little Ice Age" forced the Norse people to move south to stay alive, causing later conflict, culture blending, and sharing of technologies. Take part in that conflict today!
