The four remaining teams face another spine-chilling assignment from Ghost Adventures' Zak Bagans. This time, they must conjure up a ghostly rave party for judges Eddie Jackson, Shinmin Li and Aarti Sequeira inspired by the haunted Shanghai Tunnels that lie beneath the bustling streets of Portland, Oregon.

The final two teams face off in an epic, spine-tingling showdown as Zak Bagans takes them to Paris, the City of Lights, and the dark and haunted catacombs that sit under the streets. Host Eddie Jackson, along with fellow judges Shinmin Li and Aarti Sequeira, crown a winner to claim the title of Halloween Wars champions and take the trip of a lifetime to one of the most haunted cities in the world!
