Look out in the game CD for an MP3 file named "explixi". Not heard anywhere in-game, it is a mix using several of the walker voices over a fast-paced synth tune.
A lot of the walkers have names "greekicized" from pop-culture icons - a guard is called "Dirty Harricles", sportsmen named "Gretzykles" or "Bobbi Orcas" and a pair of water carriers named " Abbots and Costellos". The game has a sharper sense of humour than all other games of the City Building Series, ranging from walker names to hilarious (and often overacted) mission introductions.
Zeus is the third title from Impression's city-building series. Their previous efforts were Caesar series (1,2, and 3) and Pharoah (with the Cleopatra expansion pack).
