here is the concept, I started to make the map but I am having trouble with getting it down using the upward ramps and stuff. Here is what I got so far, Can't really figure out how to create the middle either.

Like how exactly do I fix up the terrain without it glitching out all the time? Do I really have to manually set each tile? Because It is a pain in the ass just to get one to match up with the surrounding tiles all the time.
edit- btw it is a 64x64 map and tanks need to not be able to shoot nats from other side and I'd prefer if middle was not so tight and tankable from nat cliffs. modified by SpoR
