Do you think you’ll make it to sunrise?
Step into the darkness this summer for an exclusive, spine-chilling 18+ Blackout experience.
Drawn off the road into a secluded English hamlet, you arrive as the village prepares for its most sacred festival. The locals are warm, the cider is sweet, and the golden light lingers long into the evening.
You were never expected. You were chosen.
As the sun finally dips and the longest day gives way to night, something shifts. Smiles linger too long. Old songs echo through the fields. The ritual begins.
Before dawn, one of you will be named the Harvest Child.
This exclusive 18+ after-hours experience is for those who crave something darker than summer revelry.
