Adds 30 new terrains for random maps. Also, optional mod for Tzar that adds a few useful things. Both are separate and work with each other.
A VERY rough video showing the 7 new terrains for random maps in Tzar: The Burden of the Crown. It gives you a general idea of what they look like.
Where are the .wdt files? :S
It's under the "addons" tab and everything is decompressed into folders.
