"Nemesis Sub-Terra is a drop tower dark ride at Alton Towers theme park. The ride opened to the public on 24 March 2012. As of August 2015, Nemesis Sub Terra is classed as Standing But Not Operational, with the park giving no indication of a re-opening date. It is based on a continuation of the back-story of the park's inverted roller coaster, Nemesis. It centres on the discovery of a nest of eggs in a network of underground caves."@en . . . . . .
