ALTIS

"Clocking-in at 270 km², Altis truly is the star of Arma 3. From expansive cities to rolling hills, from wind farms to solar farms, whether steamrolling your tank across the southern plains, or waging asymmetric warfare from the northern hills, the Altis landscape lends itself to some of the most detailed locales and varied engagements."

Notes : The map is not complete as you can see on the pictures, therefore I would put a download link when the map looks better and will approach to the maximum of the game.
