Build up your economy and upgrade very fast to the Mythic Age. Then, upgrade as much as possible while building your army. After that, destroy one temple near a town center to the west to get "Meteor Power". Your meat, wood and gold should be at about 20,000 and your favor at 200. Then, make a Wonder and send all your villagers to build it. Then you will get the gift from Zeus which will make Arkantos a very powerful demi-god. Note: You will lose the rest of your god powers, but it is worth it. Then, using the god power on Arkantos, start your attack. Note: A Poseidon statue must leave some queued on your military.
Bring about five Laser Bears and attack Troy. You need to destroy three fortresses to win. Destroy the two on your left and leave the last fortress (on your right). After you have destroyed Troy, destroy the last fortress.
When playing the King of the Hill map, be Poseidon. As soon as the game starts, cast Lure just beside the Plenty Vault in the middle of the map. The Lure Stone will capture the vault. While it will not win you the game (unless if the vault is on an island), it will get you extra resources in the time it takes your opponent to try to reclaim it.
In the seventh or eighth campaign, the heroes Arkantos, Ajax, and Chiron must find three relics and safely return to the three temples. On their way they meet Shades (a type of unit that is invisible to enemy units). Shades cannot attack buildings but are very effective against Myth units. Click the Shade and select any enemy Myth unit (for example, Colossus, Hydra, or Kraken) to attack them. The Shades grab the enemy Myth unit's souls and diminish away. They can be used only once against a single Myth unit. Do not use Shades on ineffective Myth units such as Minotaur or Cyclops.
