I believe that the second season of Stranger Things was initially slated to arrive on Halloween, but Netflix has announced that the official premiere has been moved up to October 27th. Netflix also added an awesome poster and teaser to go along with the news. Check out the entire poster and the teaser below.

The official synopsis reads:
1953, date unknown – MKUltra comes to Hawkins and begins experimentation
1979 – Police Chief Jim Hopper returns to Hawkins
1983, November 6 – The vanishing of Will Byers
1983, November 8 – The vanishing of Barbara Holland
It’s 1984 and the citizens of Hawkins, Indiana are still reeling from the horrors of the demagorgon and the secrets of Hawkins Lab. Will Byers has been rescued from the Upside Down but a bigger, sinister entity still threatens those who survived.”
