Warning: If you don't want "Stranger Things" spoilers, don't watch the new trailer or scroll through this gallery.
During the Super Bowl Sunday, Netflix released the first trailer for "Stranger Things 2," which debuts on Halloween.
The trailer begins with a vintage commercial for Eggo waffles, a favorite snack of Eleven (Millie Bobby Brown). Then it shows her, bloody nose and all.
Dustin (Gaten Matarazzo), Mike (Finn Wolfhard) and Lucas (Caleb McLaughlin) ride like the wind on their bikes while dressed as "Ghostbusters" characters for Halloween.
Police chief Jim Hopper (David Harbour) tries and fails to keep something at bay. He still has his badge, but is he also working for another elusive government agency?
When we left Will (Noah Schnapp) at the end of the first season of "Stranger Things," he coughed up a creepy critter. Here he's being checked by a doctor as mom Joyce Byers (Winona Ryder) looks on. But is this doctor legit or working for the bad guys?
This homage shot reminiscent of the '70s sci-fi classic "Close Encounters of the Third Kind" has Will, or maybe Mike, about to open the door to see the ultimate monster.
