Severance is far from the only sci-fi hit in the . The dystopian thriller aired its second season last fall, and season 3 is well under way. Here’s everything we know so far about Silo season 3.

Silo season 2 ended on a bit of a cliffhanger.

While the series to this point has been set almost exclusively inside underground silos, the season 2 finale shook things up.

Creator and showrunner Graham Yost confirmed that’s a sign of things to come:

“Yes, we will be outdoors, and we will be in the world, and there will be sunshine,” Yost said, speaking to the parts of Season 3 that will be brighter.

Apple TV+ has already greenlit all four seasons of Silo. And once season 4 airs, the series will be complete.

“It has been a richly rewarding experience to adapt Hugh’s epic novels with our partners at Apple, and we are thrilled to have the opportunity to bring this complete story to the screen over the course of four seasons,” said showrunner and executive producer Graham Yost. “With the final two chapters of ‘Silo,’ we can’t wait to give fans of the show an incredibly satisfying conclusion to the many mysteries and unanswered questions contained within the walls of these silos.”

Silo fans will be glad to hear that season 3 is making good progress.

There’s still plenty of post-production work ahead before the new episodes can be released. But it’s a great sign that work is moving ahead with no delays.
