Today, Sierra Studios and GameSpot bring you the demo premiere of Zeus: Master of Olympus. The demo lets players take control of a Greek city while Perseus is away rescuing Andromeda from the Kraken. Other cities will see how the players handle the situation and put their leadership skills to the test. Also available for download is an add-on, which will add the introduction movie and bring speech to the units. For more information about Zeus, take a look at our review. The playable demo and the add-on can be downloaded from the links below.
