Now four European kingdoms led by spectacular leaders, including the famous Richard the Lion-Hearted and Philip of France, have sprung up in the desert. The Saracen king, Saladin, gathers his troops in an attempt to expel the invaders.

Scenario
Quite easy. Just follow the instructions. You have to go down to the north end of the map in order to get into the city. There are very few opponents along the way. Once you made it to the wonder you receive additional troops. Leave the city and head to the east. Vaporizing the enemy town center should be no problem with your siege equipment.
