John Wardley is a British roller coaster designer. He is known for having worked with the Tussauds Group and Merlin Entertainments to create rides such as Nemesis and Vampire. He also played a part in the design of RollerCoaster Tycoon 3. Due to this, his name is one of the game's cheat codes. This cheat code removes all height restrictions.
He retired in 2013 after working on The Smiler.
But did still consult for other future attractions of other European parks like Flug Der Daemonen in Heide Park in 2014 and Wicker Man in 2018.
