Age of Empires Online

Once Agamemnon returns to Mycenae from Troy, he'll have some new quests for you. After finishing Big King, Big Ego you will unlock this quest.

The concept of this quest is pretty basic. Defend the city. The attackers will come from both the western and eastern roads with a couple of smaller groups coming down the middle every few minutes. What I did for this was I started off by building another tower between the two, along the NW wall, added a gate in front of both fortresses (well I did this later on, but starting off this way helps) and stacked on about a dozen villagers on the gold mines (2 in the SW of the city, one outside the east wall should be next, then the one up and to the left of the main gate).

For me, I was only in my teens so I didn't have any golden age stuff, thus I relied heavily on the super epic Somatophylax Veterans which are created by the fortresses (requires the purchase of an advisor from the Mycenae shop). I kept both fortresses busy pumping out Somatophylaxes (kept 2 full rows of production in the west fortress and one row in the east) to the turning point/intersection of the western and eastern roadways. For the western end, this would cause the units to move up once enemies approached, thus blocking off the roadway as they wedged themselves between the water and cliff. The eastern end is far more tame, consisting more so of archers that can be dealt with no problem. By about 8 or 9 minutes in I put a fortress just inside the front gate which turned out to be unnecessary outside of a few spots where my westside got wiped out. Using this method, none of my walls were even scratched... hopefully it all works out for you.
