Sauerland is a beautiful 35km x 35km map made for Arma 2 consisting of rolling hills, rural farmland map with enormous cities. They used Geodata from the Sauerland area of Germany to create its topography.

The map is used as an alternate by Epoch, so many of you will be aware of it.
It would be great to have ANY variant of Dayz SP that uses Sauerland.
