I figured to post this in Art&Stories because at the moment I still don't know much about mapping atmos/power/area stuff to feel I'd actually help as a mapper or whatever.
Besides just placing tiles, I sprited the grass, jungle, sand, animated water, and barbwire, but that's it.
I'm happy to give the files as I don't know if I can or will finish it.
Map I haphazardly pieced together with screenshots:
A bunch of screenshots of various locations,(most buildings are empty and uninteresting):
One of the warehouses:
Abunch of other close-ups:
I intentionally used rock walls to section off parts of the map into individual valleys, yet having wide enough bottle-necks that both sides can't simply camp into deathtraps like I see with 2-tile wide hallways.
The idea behind this was that combative fronts naturally form along the various valleys as the battle-lines push back and forth, requiring command to use, monitor, and hold each section strategically.
Also, if its late in the round and there's that one runner that's SONICing everywhere, marines could form choke-points at key intersections of the map and cut them off from delaying the round. Hopefully, anyways.
I figured to put the Hydroelectric Dam(Engineering) in the center of the map, so engineers stationed there are in constant action, rather then growing bored in the outskirts and wandering off.
Edit: Below are some additional screenshots after some more work all over the map. I mostly tried to make things prettier all over , roads and the jungle fiona primarily:
