Netflix has released the final trailer for Stranger Things 2, bringing us fresh footage of returning heroes, new allies and an increasingly dangerous Demogorgon.

As the Upside Down continues to leech into the real world, the citizens of Hawkins, Indiana come together to save not only their town, but all of reality. Will's visions of the evil alternate dimension continue to plague him, but even though he seems helpless in the face of the otherworldly evil, his best friend Mike believes Will, not Eleven, holds the key to the Demogorgon's final defeat. Of course, since it's been announced that the series will return for at least two more seasons, and possibly even three more, we know the Upside Down will be back in the future no matter what happens in Season 2, but let's not ruin the kids' optimism.
