Nemesis is an inverted roller coaster located at the Alton Towers amusement park in England. The ride's concept and layout was devised by designer John Wardley. It was manufactured by Bolliger & Mabillard (B&M) and opened in March 1994. It is located in the Forbidden Valley area of the park, adjacent to Galactica, a B&M flying roller coaster; Nemesis: Sub-Terra, a dark ride manufactured by ABC rides, and The Blade, a HUSS Park Attractions pirate ship ride.
The 716-metre-long (2,349 ft) ride stands 12.8016 metres (42.000 ft) tall and features a top speed of 80.5 kilometres per hour (50.0 mph). The four-inversion roller coaster was one of the first Bolliger & Mabillard rides to be installed outside of the United States and the first in Europe (as an independent company). The ride has been very well received, consistently ranking highly in industry polls.
In 1990, Alton Towers added the Thunder Looper roller coaster; the addition was only temporary due to planning restrictions imposed on its installation. The park began planning for a new roller coaster which would open prior the closure of the Thunder Looper. They desired a roller coaster that was big, different and exciting, but they were constrained by the tree-level height limit imposed on the park.
Alton Towers approached Arrow Dynamics for the new roller coaster. The Utah-based company was working on a prototype of a pipeline roller coaster, similar to TOGO's Ultratwister design.John Wardley worked on the design of the ride which was originally to be themed around a secret military facility, codenamed "Secret Weapon 1" (SW1). Due to the design of the ride and the height restriction imposed on the park, SW1 would only have a track length of 300 metres (980 ft). Development of the project was put on hold a short time into the process, due to the financial problems being encountered by Arrow at the time and technical problems with the ride's design. The project was revived a year later under the codename "Secret Weapon 2"; rock blasting was used to clear more space for the larger ride. The project was again abandoned when Wardley rode the prototype, describing it as "very slow (and rather boring), looked cumbersome, and was very energy inefficient". The park began to look for an alternative.
