Curse at Alton Manor

The original Haunted House was designed by The Sparks Group and John Wardley and was the largest haunted attraction in Europe at the time of opening. The bespoke ride transit system was built by MACK Rides and designed to allow a high throughput whilst leaving the cars to travel the ride separately, and at varying speeds in different areas. Opening in March 1992, the Haunted House gained considerable publicity and remained one of Alton Towers' major rides for many years.

By 2002, many of the original scenes had been altered by the park on an ad-hoc basis. The park decided to revamp the attraction through the addition of light guns in the ride vehicles, which allowed guests to interact with the ride's scenes by aiming their guns at infrared targets scattered throughout the ride. Each target hit by a rider would add to their individual score shown on a display in each car. Towards the end of the 2002 season, a poster was placed outside advertising the new name and opening date, announcing: "Whatever you do, don't miss! Duel - The Haunted House Strikes Back!".[5]

A new soundtrack composed by David Buckley played on a loop throughout the ride, replacing the original eight zoned tracks. Other changes to the ride included replacing many characters with zombies, and reducing the capacity of each ride vehicle from six riders to five. The revamped ride reopened in April 2003.

For the 2008 and 2009 Halloween 'Scarefest' event, the ride opened as "Duel: Live!" featuring several live actors around the ride.[7] Guests waited at the door, before being let in by a maid or a butler. Inside, the laser guns and targets were switched off and the music replaced with a more haunting soundtrack. In 2008, Duel ran as normal during the morning and afternoon before becoming to Duel Live after 3:00PM, but ran all day in 2009. In 2010, the overlay was renamed "Skelvin's Haunted Adventure", themed to the park's Halloween mascot 'Skelvin', and the ride soundtrack was replaced by the Beetlejuice title music.

Guests queued past gravestones in a wooded area, before entering through the front doors of the house. The interior queue meandered through themed rooms, depicting a darkly-lit Victorian vestibule and drawing room. These scenes featured a number of illusion, themed aroma and haunting music. The second room was also slanted at an angle to disorientate guests. On the left side of the room was a doll's house which used a Pepper's Ghost illusion to show the ghostly image of a little girl named Emily Alton and her pet cat called Snowy playing within it.

In the station, riders boarded the ride vehicle. Once beyond the platform, the vehicles accelerated away from one another to take riders into the scenes individually. The first scene took riders past cracking stone walls that appeared possessed. This led to the Grand Hall, which looked seemingly empty before a large demon appeared overhead between two columns. This effect was originally achieved with parallel mirrors and timed lighting. The car then swerves right into a dark corner, where the demon re-appeared offering a teacup (later changed to holding a knife and giant rat).

The car traveled into a stone chamber and towards large skull-shaped effigy into skull's mouth. Inside, a large rotating trommel tunnel gave riders the sensation of turning upside-down. The ride continued into a stone corridor with large Gothic windows either side. Large ghouls lurched from windows towards riders, before the car passed the largest window with a giant staring face.

The next scene took riders weaving past large spiders with a high pitched drone noise playing and a voice whispering 'are you scared of spiders?', ending with a giant-sized spider suspended overhead. Riders then entered a corridor where a skeleton pulls a lever on a fuse box, turning out the lights. This scene originally featured a large ghost that flew overhead down the corridor. This was removed after its first year and replaced by a new scene featuring skeletons in 1993. In turn most of this scene was also removed in later years. The car then turned through a series of tight bends in the dark, as screaming heads fly overhead using a UV-strobe effect.

Riders then traveled into a sinister garden at night, at which point the car slowed down. A crashed hearse could be seen ahead, with an undertaker gesturing you to come closer and ghosts flying out of an open coffin (using a Pepper's Ghost illusion). Further into the garden, a troll-like ghoul leapt out from rocks on the right. A statue of Death stood at the end of the garden. Behind an archway, a stone column suddenly turns to reveal a tall, thin demon before the cars accelerated onwards. The finale then traveled further into the garden, where riders traveled through a possessed rocky swamp as various monsters, serpentine creatures and ghouls appeared.

With the exception of the doll's house, many of the effects in the preshow room were removed or altered in the Duel revamp, including the optical moving-eye portraits, to be replaced by TV screens playing a pre-show video informing guests that 'a controversial genetic surgeon called Dr. Nicholas Roodyn had vanished leaving behind a legacy of unfinished research into the reanimation of the dead. The undead have risen, a legion of zombies has emerged, drawn to the home of their creator. Evil has spawned from the heart of this house, and you must face your fear', guests would be armed with lazer guns, and you should 'prepare to duel'. on the ride lots of animatronics were changed and lots of laser targets were added into the ride and some new animatroics were added (mostly depictions of various zombies) and lots of lighting effects and music was changed. A screaming zombie was added before entering the tunnel, as well as the splitting head (originally from the finale) at the end of this tunnel. Zombies were also added to the windows were demons used to be and some in the spider scene. The original swamp ending was entirely replaced by an industrial basement where zombies appeared from barrels, windows and overhead walkways.

A large crypt outside the ride which used to showcase a zombie holding a lazer gun when it was Duel has been repurposed into a tomb for Emily Alton and the top section of the crypt has been moved to mark the rides entrance sign. Guests queue through the same graveyard in Gloomy Wood used for Duel, but with new theming elements such as new tombstones with epitaphs that reference to previous attractions at the park, old toys such as dolls, stuffed animals, building blocks, and plaques displaying short poems placed around the queue that introduce riders to the story of the ride. Guests enter the manor house now repossessed under mysterious circumstances, where it is up for sale, and that an open house is being hosted. The first room features a real estate listing for the house priced at £1,992,000 (a reference to 1992, the year the Haunted House originally opened).

Moving into the second room, a pre-show plays further explaining the backstory of the ride. A scale-replica doll's house based on the mansion sits at the center of the room. An unseen narrator explains that in 1892, the Alton family hosted a lavish party in celebration of New Year's Eve, but at the stroke of midnight, a violent storm ravaged the mansion killing the Altons and all of the guests in attendance. However, young Emily, the only child of Mr. and Mrs. Alton, mysteriously disappeared and remains unaccounted for. Suddenly, Emily's voice is heard whispering "Let me show you what happened", and the ghostly images of Mr. and Mrs. Alton during the fateful night appear inside of the parlour of the doll's house. Emily enters and begs her father for permission to attend the party. Mr. Alton cruelly dismisses Emily to her room in the attic, calling her a "wretched little creature". Emily appears in the attic crying. Angered, she picks up a doll and "snaps" its neck. A now-possessed Emily begins to glow with violet-coloured supernatural energy which spreads to the rest of the doll's house causing her parents and the party guests to vanish. The entire room of the ride now becomes bathed in ultraviolet light and reveals manic scribblings by Emily written all across the walls.
