- Objective: Destroy the five towers of Jerusalem.
You have to be quick at the beginning. First of all, two relics can be captured. One is located at the Hospitallers base on the left, and the other one is on the right edge of the map. Furthermore, as you must not destroy any Jerusalem monasteries, and you only get one chance to do this.
It's a good idea to settle down near the relic at the right. Jerusalem is quick, and with your town center you can defend it until your monastery is built. In the meantime, pick your army and wipe out the Hospitallers. They have little defense, but troops from Jerusalem and the Knights Templar may aid them. After that, go further to the south and destroy some farms and camps. This will result in a loss of your weakened units, but it's okay since it also damages your enemies. Your town should now be ready to produce new units. Build some towers and do a little research until the first attack will arrive. Most of the time rams will be used, so this will slow down Jerusalem's attacks. It should be easy to withstand.
When destroying the five towers, remember two of them are bombard towers. It's not a good idea to attack with rams, but bombard cannons are great. Protect them with hussars, and this game should be easy to win.
