Nemesis Sub-Terra
Your worst nightmare, underground.
Take a thrilling ride deep into the Earth’s core to discover the secretive research of The Phalanx. Through a guided tour of their latest research facility in Forbidden Valley, civilians are invited to look, stay alert, but don’t touch, as they’re shown exciting glimpses of a Nemesis egg, their latest discovery…
We’re told it’s controlled and contained, but very little is known about the origins of the egg that sits beneath the Nemesis site. However, it’s showing signs of life, and a team of Phalanx operatives are investigating. But can they keep control?
Board the ride and embark towards your worst nightmare, underground on Nemesis Sub-Terra, as you’re taken down into the deepest location of the Forbidden Valley, venturing in the excavated caves below the Nemesis monster for a truly terrifying experience.

Experience the Drop
Your journey begins with a top-level security briefing from the Phalanx, the secretive organisation tasked with controlling the Nemesis entity. You’ll then be guided to a lift for your descent deep into the earth, towards the chamber containing the creature's egg.
Once you are seated in the observation chamber, the lights flicker. Alarms blare. The containment field has failed. You’re trapped, face-to-face with a living, breathing predator. There is only one way out: Nemesis Sub Terra!
Drop into total darkness on this terrifying Alton Towers ride. Are you brave enough?
