Warcraft Total War is a total conversion mod for Medieval II Total War. Our goal is to bring the Warcraft universe into a Total War game. This mod will feature epic battles with units from the Warcraft universe and a new campaign that will cover the events of the Third War and beyond.
I've uploaded the custom locations.txt file that we have, in order to fix the demo-issues with custom battle maps being water for most of the battlefields.
This text-file that you will find under the files-section will fix this issue.
