For the 2008 and 2009 annual Halloween 'Scarefest' events held at Alton Towers, the ride became host to "Duel: Live!" This attraction featured live actors situated in different scenes around the ride, to scare riders while in their cars. The laser guns and all the LEDs were switched off, so that riders were not distracted by the shooting and focused on the ride. The music was replaced throughout the ride, with a different, more atmospheric piece used instead of the usual Duel theme.
Duel Live made use of the original outdoor queue line, often with other actors roaming the wooded area. For the 2008 version, the queue featured gravediggers and werewolves creeping up on the guests, though in 2009 this was reduced to one actor in a hooded robe. Guests waited at the door instead of walking straight in, before being greeted by either a maid or a butler (the performers alternated during the 2009 version, but in 2008 only the butler featured) and given a brief talk about what was inside and why the guns were switched off. The TV screens in the Drawing Room were covered with cloth and muted, and the original spooky music turned up; the room being similar to what it was in the original Haunted House. During the 2008 event, the maid jumped out at guests as they entered the Drawing Room.
