I was thinking of a thin map with a single, huge metal patch in the center. That would force the player to focus on that zone, leading to .. maybe something fun ? well that's the point
Each side would have a strongly defendable environment, to be able to survive a while and prepare an offensive when the adversari/es are sucking the metal
here's an image to give an idea :

white is height ..
It would probably be around 20*4
As I'm not sure about the starting position I drew a different one for each side .. if you have idea of better one
well, any comment ? does that plenty suck, or should I try to do something ?
