You are forced to go in one direction around a circular road because of ramps that allow passage on one side but not the other. There is a central area with three open levels. On the top level, there are lines of sight into each base. Connecting the bases to the central area is done by bridges. On two of these bridges, there is a Splaser, and a SPKNR. The bridges are over the road, so you can stand on the bridge and destroy oncoming enemy vehicles. There is also two Phateons on the map, and controlling these is the key to success. They can be countered though, by the Splaser and the SPKNR.
