The experience uses state-of-the-art technology, including projection mapping, special effects and lighting to bring iconic moments and unspeakable creatures from the Harry Potter films to life, Universal said.

“As darkness falls in Hogsmeade, the all-consuming Dark Arts will be unleashed as ominous green light and fog flood the village. Death Eaters — devoted followers of Lord Voldemort — will appear and lurk amongst guests with complete disregard of wizarding laws,” Universal said in a news release.
