These are all ground spawns they can appear in any where in zone. I got most all in center of map there using teleports A, B, C, or D. I stayed up there in these hallways had invisibility up the entire time. Completed this set up there. It is shaped like a large cross on map will everything coming to center and hallways branching out North, South, East, West the teleports are end of each wing. Run around those halls and your will see them.
