What’s more traditional than walking through the 13th Floor on Halloween? San Antonio’s favorite haunted house is back for yet another year. With all new themes, Cursed: The Ritual and Biohazard, the 13th Floor will be packing even more chills and thrills than last year. Mixing werewolves, voodoo priestesses and mutant alligators seems like the perfect recipe for nightmares. Will you be cursed and fall into an ancient ritual? Or will you venture into the depths of an abandoned water plant that has collected toxic sewage for years and has created some sinister creatures? Both sound equally terrifying but are sure to get your heart racing in only the best ways.
