The mafia came to Ben's town, but Ben would not let them be in his town as he knows that they only bring trouble. He grabs a gun and drives his car to confront them. He is well skilled on the driveway and he knows that they can't corner him if he just keep going.
The idea here is to destroy the enemy van as fast as possible as there would be more. Since this game is on the road, you can expect lots of cars passing by and you don't want to be hit with these cars. The toughness of the enemies depends upon their colors.
