Zeus: Poseidon Expansion is a small adventure in the life of Atlantis and other aquatic locations. As the title suggests, the main god here is not Zeus, but Poseidon witch can be quite confusing in the beginning, especially to Legend of Olympus connoisseurs that have actually read it. In any case it's a nice derogation from the original title that it's sure to please any city builder fan.

Hero's Hall:
Sometimes, a Hero's Hall must be built in certain places. For example, Thesues' Hall needs to be built by the palace, surrounded by walls and have good appeal. On maps where space is at a premium this can be difficult to accomplish. To get around this, after you have filled the requirements to summon the hero, and while the hero is on his/her way to the city, you can demolish the hall and any of the structures you had to build to meet the requirements. Then, rebuild the hall anywhere that is connected to a road. The hero will not care and will serve your city as usual.

Earthquake:
If an earthquake happens and the land is no longer able to be built on, use the Fireballs from Heaven code to rain fire over the affected land. Then, clear the land as normal and you can now build freely upon it.

Audio easter egg
On the Poseidon disk, go to the Audio/Music directory. There you will find the music from the game, and more importantly, a song named ''Ekplixi.mp3''. It is not from the game, but it is a silly song featuring many quotes from the walkers in the game.
