Each has it’s corresponding climate, too. In one mission you have to fight the vikings on Greenland in deep snow and in another you fight the natives of Africa in a mix of desert and veld.
Also there come 12 new maps for the free game-mode with this add-on, there’s now also a editor in which you can build your own maps with the only limitation that you can’t make a map on which you can use ships.
