Derren Brown's new ghost train attraction for Thorpe Park is still wrapped in secrecy. We know visitors will sit in a suspended carriage and that the experience will feature multiple HTC Vive headsets. We know that it's a "multi-sensory" ride combining live-action and special effects. But otherwise, the details are scarce. What we have been told today is that the ride will open to the public on May 6th. Better mark those calendars.
