One Hot Wheels Robot Cyborg Blaster Trick Tracks Starter Set.  It is new in manufacturer's package and has never been used. 

Features include:

• One Stunt Set with two pieces of track and cyborg robots
  
• One Vehicle
• A wild, thrilling ride where one cool stunt triggers the next
• Connects with other Trick Tracks stunt sets for additional stunts (Blast Launch, Slam Bridge, Spin Blade, Radar Rocket and others -- sold separately)
  
• Build the action and excitement any way you want!
• Assembly required
• Not for use with some Hot Wheels Vehicles

The objective is to set off a series of stunts to blast and defeat a robot. The first car triggers the blue robot to turn and shoot a missile at the yellow robot. If you defeat the robot, you will launch the second car on the track! Note: one car is included with this set, so you will need an additional Hot Wheels car to complete the stunts
