Netflix has made it official and renewed its surprise hit Stranger Things for a second season.

While the news had long been expected following the '80s-based thriller's massive buzz, the streaming platform had not publicly acknowledged its plans until Wednesday, when it released a new teaser video. 

Netflix has also confirmed the new installment will arrive in 2017 (like the summer or later), consisting of nine episodes (just one more than season 1) and skipping about one year to the fall of 1984.

Although most of the key characters will return (with four new ones), creators Matt and Ross Duffer also said today Eleven’s involvement is still “up in the air," leaving much to speculation about the star character played by Millie Bobby Brown.
