This is only for use in scenario editor.
I removed (hopefully) all of the elevations on the map.
I know you can remove all of the elevations on the map yourself but it can be a bit of a hassle. This is for the people who want to start creating the scenario straight away without the built in elevations on the scenario editor map.
just extract it to the scenario file in the age of mythology file then start age of mythology: the titans expansion then open scenario editor then load blank map.scx
