Immobilized- When a vehicle becomes immobilized it is moved to the direct outside of the track. The vehicle may still shoot if it had not suffered a weapon destroyed result. At the beginning of the following turn roll a dice. On a 4+ the pit crew has come out and fixed the vehicle and it may move as normal that turn. If you build and paint your pit crew (3-5 models) your roll is increased to a 3+.
Wrecked/Explodes- The vehicle will respawn with it's rear touching the last waypoint.

To set up the track mark off a lane that is 12" wide around the edge of a 6'x4' table. Mark a waypoint halfway along each table edge. One of the waypoints will be the starting line. Place 2 mines equally spaced along the line from the inside of each corner to the outside of each corner. When a vehicle moves within 2 1/2" of this mine it rolls a dice. On a 5+ the vehicle evades the mine. If the vehicle ends it's movement within 2 1/2" or rolls a 1-4 replace it with a large blast marker. Any vehicle that is hit by this blast will receive a glancing hit on a roll of 2-5 and a penetrate on a roll of 6.  Place 2 pieces of terrain along each short edge track side. Place 3 pieces along the long table edge. If a vehicle moves through a piece of terrain roll a dice. On a 1 it becomes immobilized.
 
Roll for initiative with 2d6. Place each vehicle in rows of two with each vehicle 1" behind the previous one. This is the order the vehicles will activate in the first round. No vehicle may fire in the first round and each vehicle must move at least 6" each round. Each vehicle receives 1 pt for every wrecked/explodes result done to another vehicle up to 5 pts. The first vehicle to cross the finish line 3 times receives 7 points, the second 5 and the third 3. Each other vehicle receives 1 pt for competing in the race.
