Depression

I haven't thought of a grand map name yet, but my ultimate goal is to make this map into a desert one, much like Lost City and Antiga Prime combined in a sense, with abandoned terran outposts, dig sites, garbage, metal scraps, cracks, and whatnot. I need to work on the layout some more, and so I decided to let you guys in on it and tweak it a bit.

The primary issue is the center since I am not 100% sure what to do with it. I could make it pathable but that would make nat2nat rush distances very short.
