Haunted House at Tivoli Friheden in Aarhus is an interactive shooting dark ride, rebuilt in 2013 by Triotech together with the park inside an existing haunted house. Riders board four-seat police cars with built-in guns and shoot flesh-eating zombies that threaten to take over the amusement park, scoring points for accuracy. The ride lasts about three minutes and photos of the riders appear on a leaderboard. There is no minimum height, but the park recommends age 8 and up.
