Stranger Things has released its highly anticipated trailer for part two of season four - and it shows the Hawkins kids facing even more terror from monster Vecna than they did in part one.
The Upside Down enemy Vecna has been terrorising the residents of Hawkins so far in season four of the Netflix sci-fi hit, but things are set to get a lot worse as the trailer shows the menace ramping up in the next episodes, due to drop on 1 July.
Vecna's voice can be heard telling Eleven (Millie Bobby Brown): "Your friends are not prepared for this fight. Hawkins will fall."
He also adds threateningly: "Your friends have lost."
Eleven is on her way back to Hawkins from California (via the underground lab where she was reintroduced to her memories of Henry who became Vecna after a bloodbath attack on the other numbered children in the lab) to try to help out her old gang and save the world once more.
However, this time the threat is more serious, as Will tells Mike: "(Vecna) won't stop until he's taken everyone."

Even older teens Steve, Robin and Nancy seem unconvinced that they will win the battle this time, while Max is still using the superpower of Kate Bush's music to keep her safe in the Upside Down.
Meanwhile, in Siberia the grown ups are facing a battle of their own as Hopper, Joyce and Murray continue their danger-laden escape from prison and the monster being used to hunt them.
One scene shows Eleven standing in the doorway of Henry and his father Victor's old house where he killed his mother and sister, letting his father take the blame.
She can be seen with a trickle of blood running from her nose, a sign she has been concentrating her superpowers, suggesting they are back to full force in the second part of the season.
Creators The Duffer Brothers told a recent Netflix Geeked Week event that they were taking full advantage of their stars being older by going for more of a horror film vibe.
Ross Duffer said: "For the first time for them, we want it to be really scary...it's like let's just push this and be as scary as possible and put them in the middle of a true horror film."
Stranger Things season four volume two will stream on Netflix from 1 July.
