Enter a world of souls this Halloween, where dark beauty and deep secrets are waiting to be discovered. Mictlan, the Aztec underworld, is faithfully recreated right down to the last level – all nine of them. Indigenous Mexican culture is reanimated as part of this mind-bending experience to mark Dia de los Muertos. This is horror as you’ve never experienced it before. Over 16s only.
