Brooklyn’s most high-tech haunted house returns for its 16th year this Halloween season. Produced by students in the Theatreworks program at New York City College of Technology (City Tech), this theme park quality Halloween attraction is filled with skeleton pirates, talking paintings and a grisly bathroom. Participants trigger the hotel’s spooky surprises with a series of hidden sensors that respond to the audience’s movements. The Gravesend Inn is open for the season at scheduled times and dates until Halloween. It is located in Downtown Brooklyn at the Voorhees Theatre, 186 Jay Street — north of Tillary. Tickets are $10 general admission, $5 for students with ID and group sales.
