Duel first opened it's doors to the public in 1992 as the Haunted House. The ride was installed at the same time as the Runaway Mine Train, Katanga Canyon and Gloomy Wood as part of a major development for the park at the time.
The original ride was designed by John Wardley and Sparks Creative Services. Of note is the unique transit system developed by MACK Rides. A primary concern of John Wardley was that the most common theme park dark ride system at the time utilised a never-ending conveyor of cars (known as an omnimover). The problem posed by this set-up was that any surprise elements were lost as riders in one car could see what was happening to the riders ahead.
The new MACK system combined the benefits of continuous loading in the station with the added ride experience of moving along alone in the dark. The new ride system was incredibly complex (even by today's standards!) and caused quite a few headaches during development to get it working properly. Because of this it is still to this day the only one of its kind in the world.
In spite of teething troubles the ride ran successfully for many years, however it's popularity eventually began to wane. For the 2003 season new props were added, a new story devised, and an interactive laser gun game introduced; Duel - The Haunted House Strikes Back was born.
The ride adopted a new story line based around the disappearance of a scientist who was studying reanimation of the dead. The house is now overrun with zombies and a family of other monstrosities. The rider's mission? To venture into the depths of the house, and make it out in one piece!
