The teaser was first unveiled on Sunday Brazil's CCXP convention, and after showing fans the episode titles in Portuguese, the teaser hit Netflix social media in English on Sunday evening. There are eight titles, and while we have no real context for them outside of previous events on the show just yet, the internet has already begun trying to parse out what they mean.
In case you don't feel like playing the video again, the titles are:
"Suzie, Do You Copy?"
"The Mall Rats"
"The Case of the Missing Lifeguard"
"The Sauna Test"
"The Battle of Starcourt"
The new season wrapped up filming last month, and so far all we really know is we can expect some new character, a new location (in particular Hawkins' new mall, which is teased heavily in these titles) or two, and higher stakes. We also know, as the teaser confirms, that the season is set in the summer of 1985, so plan your pop culture reference drinking games accordingly.
