Ivan looks up, recognizing J more from his time as a musician than his time as a rescuer. He moves over a little where he sits, so J can get a better view of the map.

"The city isn't as big as Vista City. It doesn't have nearly the number of layers." He bends an edge over to show that the other side of the map is printed on as well. "Any vertical consideration is going to come more from skyscrapers and multi-story than another city layer completely. That can work in our favor... but it can also give us trouble too."

If the brain chips can't track elevation, then more layers would give the rescuers an edge when spiriting away a musician. There are more places for the label to look. On the other side, fewer layers also mean a more straightforward confrontation. There are only so many directions an attack could come from if above and below are limited.
