Pete, the VIPER NIGHT DRIVIN has an "Adult Mode" you can turn on or off in the Audio Menu system.

 When turned on, the good looking female on the playfield, who is the hitch hiker, she ends up in the back seat of the V10 VIPER, and she moans and groans VERY LOUDLY whilst she is getting hammered by the driver. It makes the game very interesting and unique to say the least, plus when you then add in the Glow Balls, plus the Black Lights, this is probably one of the best n unique pinballs ever made. The Black Lights make the machine, like 2 completely seperate pinball machines. Its like playing a pinball machine in full colour, then playing a pinball in complete black n white like u are literally watching a black n white Television. It is an amzing game that hardly anyone has had the chance to experience. If u like Twister, like I do, this is 5 times better.
