What I held off to post for a little while is that I in fact made an entirely new theater for DTA 1.11, including all tilesets the other theaters have as well; such as
water cliffs, shores,...

rivers, roads, normal bridges, high bridges,...

other ground types that can be placed on top (I already showed the dirt LAT in an earlier news post),...

trees (converted from the temperate theater),...

and more.

Just like how the snow theater is actually part of the temperate theater, this new theater is likewise part of the desert theater, which allows mappers to get extra creative by mixing two theaters together.

Since this theater is still brand new, there will only be a few maps that use it included with DTA 1.11's initial release (such as j4m3sb0nd's "The Sandbar", shown in in the image above), but more can of course be made post-release.
