This large 4x4 off-roader has flashing blue emergency lights (controlled with the siren), functional head and tail lights, transparent windscreen, an open roof and black, bulbous, treaded tires. A passenger can ride in the rear seat. It has an engine sound similar to a heavy car. Like most four-wheelers, it's relatively easy to control.
The siren sound and lights can be controlled by holding the appropriate button ("F" on PC). Pressing the button (not holding it) activates the horn, which is a typical car-horn sound.
The Swamp Police 4x4 is based on the 4x4 in the LEGO set (Swamp Police Station)).
