Production has officially begun for "All of Us Are Dead" Season 2, years after the initial zombie outbreak at Hyosan High School. The new season shifts to Seoul, featuring returning characters like Nam On-jo, now a university student, facing a deadlier, more aggressive virus. The expanded world introduces new characters, including university seniors and a National Intelligence Service leader, alongside familiar faces grappling with past trauma and evolving threats in a post-apocalyptic society. Filming is underway, with a potential release in late 2026 or early 2027.
