Stranger Things' creators have warned "nothing is normal anymore" in the upcoming series.

The horror drama series has just released a full new trailer for the upcoming season five, depicting Hawkins under military quarantine, and Ross and Matt Duffer have teased that things are "in chaos" right from the first episode.

Ross Duffer told Netflix's Tudum:"I think what's unique about this season is that it starts a little bit in chaos because our heroes ultimately lost at the end of Season 4.

"We usually set up their normal life and how they're going about school, and then we introduce the supernatural element. But in this case, this season is sprinting from the start."

His twin brother added: "[The gang are] not experiencing normal life. Nothing in Hawkins is normal anymore.

"Their movement is restricted, and there are Big Brother cameras everywhere. So not only are they active -- their everyday, normal lives are anything but."

Executive producer Shawn Levy has promised fans are in for a visual spectacular with the new episodes, but insisted that hasn't come at the cost of an "emotional" story.

Shawn, who directed two of the new episodes, said: "The action is next level, the visual effects are next level, but I'm also happy to say that the emotional center remains the same. "And part of the magic of this show is that even as we evolve, even as the storytelling becomes more epic, it's always anchored in these characters that we love."

The first installment of season five premieres on 26 November and is set in the autumn of 1987, with the central characters determined to find and kill Vecna (Jamie Campbell Bower).

An official synopsis teased: "But [Vecna] has vanished -- his whereabouts and plans unknown.

"Complicating their mission, the government has placed the town under military quarantine and intensified its hunt for Eleven, forcing her back into hiding. As the anniversary of Will's disappearance approaches, so does a heavy, familiar dread.

"The final battle is looming -- and with it, a darkness more powerful and more deadly than anything they've faced before. To end this nightmare, they'll need everyone -- the full party -- standing together, one last time."
