Nemesis is a steel inverted terrain roller coaster located at Alton Towers in Alton, Staffordshire, England, United Kingdom. Built by Bolliger & Mabillard, it opened in 1994 and was the first inverted roller coaster outside of North America. It is also the first Bolliger & Mabillard coaster outside of North America.
Nemesis features four inversions which twist around the ground, trees and the 'river of blood'. The entire ride is built partially into the ground to keep it below the treeline. Nemesis has a pre-drop, a feature employed by the ride manufacturer to reduce strain on the lift hill. When it first opened, Nemesis' track was painted an off-cream color and its supports were painted black. When the ride was repainted in 2016, the track became white with a rust effect.
There were originally two other plans for Nemesis (called Secret Weapon 1 and Secret Weapon 2). The first was scrapped due to height restrictions and the second was a pipeline roller coaster. John Wardley, designer of Nemesis, rode a prototype but found it to have a lack of energy. This is when Nemesis, or Secret Weapon 3 as it was then known, was designed.
A sister roller coaster was built at Thorpe Park, named Nemesis Inferno, another B&M inverted coaster themed around a volcano. There was also another ride called Nemesis: Sub Terra which was built in 2012. This was an ABC Rides indoor drop tower themed around a military compound owned by the Phalanx, the organisation who captured the Nemesis creature. Many special effects were used, with the drop tower only being a small part of the entire experience. The ride closed in 2015 and currently remains SBNO.
