This is a modified version of the Hao map from the "A Xia’s Diary IV" custom campaign. It is 'enormous' in size, and has a humid climate. This map is an adaptation of the actual topography of the city of Hue, Vietnam. The map has extensive ruins and depicts the city as having been destroyed. It will be up to you to rebuild the city to its former glory!
A list of the modifications that are included on this Open Play version of the map are as follows:
1. Iron ore was added to the north east edge of the map.
2. A stone quarry was added to the northwest edge of the map.
3. The map was given a full compliment of 8 invasion points.
