Players start at the 4 corners. There is a city between each ally with strong defence. Capture the city and use the resources there. You can find/search other pathways to go into the city or the middle jungle also. It is a long game and no rushes. Enjoy it and please send back your comment to me : Miketingkachun@hotmail.com, ThanKs!
P.S. Strongly recommend: Download the map and just host it. Do not browse it with map editor because it is unfair! (Because there are some pathways^^)
Download the zip file, unzip it in your aomscenario directory
