When Stranger Things ended in 2025, we all knew it wasn't really the end of the franchise. After all, Netflix had a few spin-offs planned, including an animated series titled Stranger Things: Tales from '85 and a prequel that promised to answer a couple of lingering questions that weren't addressed in the main show.
Now, on Stranger Things Day, we finally have a glimpse of the otherworldly adventures that lie in store.
Netflix has officially announced Other Worlds: A Stranger Things Adventure, a series that will take place in 1955 in Marion, Nevada, before the Demogorgon madness took over Hawkins. The upcoming project is co-created by the Duffer Brothers alongside Stranger Things: The First Shadow writer Kate Trefry. Golden Globe-winning director Joe Wright will helm the first three episodes.
Aside from that, we know very little about the spin-off, other than it will feature a new narrative that will connect to the story that unfolded in Hawkins, as revealed by executive producer Shawn Levy:
"With Other Worlds, the Duffer Brothers and Kate Trefry craft a new ensemble and adventure that is imbued with the DNA of our flagship series while exploring a new era, setting, and all-new characters, themes, and mythology — the seeds of which may have been planted in Hawkins, but now venture into other worlds of spectacle, action, and emotion."
Of course, the most likely option is that Other Worlds: A Stranger Things Adventure will finally tell us the full story of Henry Creel, who would eventually become Vecna and try to merge the Abyss with Earth. With that in mind, the upcoming prequel could finally solve one of Stranger Things' biggest mysteries three years later.
Other Worlds: A Stranger Things Adventure should explain what the alien rock is
Stranger Things reached a point where so many characters died at the hands of different monsters that it was easy to forget that all the madness started because of a rock (kind of).
There's a gap in our knowledge of the Stranger Things mythos that hasn't been fully explained yet. Thanks to Stranger Things: The First Shadow, we know the first people to ever go to The Abyss or Dimension X were a group of scientists trying to build a naval ship called the USS Eldridge that could be rendered invisible and undetectable by other countries. Among the crew of the USS Eldridge was Captain Brenner, who was the sole survivor of the incident and returned home with mutated blood.
Captain Brenner told his son, Doctor Martin Brenner, about the existence of Dimension X. From that moment, Martin became obsessed with trying to travel to the same interdimensional world his father once happened to stumble upon. To do so, he established a military research base in Nevada and tried to crack the key behind interdimensional travel in what came to be known as the Nevada Experiment.
Now, here's where things get a bit murky. We know Martin Brenner must have succeeded somehow in his investigation, as he retrieved a mysterious rock from Dimension X. That rock was then stolen by an undercover spy for the Soviet Union, who fell into a cave near the Nevada military facility. Henry Creel eventually stumbled into the scientist, killed him, touched the rock, and the rest is history.
Unfortunately, Stranger Things never quite explained what the rock is, how it was retrieved from Dimension X, or why it has such a strong connection to the Mind Flayer in the first place, which was disappointing. Many fans believe the show lost a bit of its magic when it started unraveling the mystery behind the Upside Down and the terrifying monster trying to take over Earth.
But what made this reveal all the more underwhelming is that it didn't even fully explain what happened in the past or what the rock was. It settled for giving us a half-baked "answer" and called it a day.
Other Worlds: A Stranger Things Adventure now has the perfect opportunity to fill the gaps left by the main show. While the prequel will feature completely new characters and a new setting, it should eventually lead to the events that transpired in Hawkins, Indiana. Otherwise, it wouldn't really be a Stranger Things adventure to begin with. And what better way to do so than by finally giving a compelling answer to the mysterious rock responsible for a lot of deaths, experiments, and tragedies? That way, fans would get to experience a full, cohesive narrative that leaves no stone unturned.
Other Worlds: A Stranger Things Adventure will be released in 2028.
