Nemesis Sub Terra NEW 1

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 you’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, but this much is clear, it’s showing life signs, 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.
