Indoor Astronaut released the cooperative multiplayer railway construction game Unrailed 2: Back on Track on June 11, 2026, for PC via Steam, Nintendo Switch, Nintendo Switch 2, and PlayStation 5. The game exits roughly a year and a half of early access with the addition of a seventh biome, the Underground Unit, described as a secret research facility of the United Railway Bureau. This area introduces laser barriers, hidden buttons, and a new enemy: the floating AI Manager of the United Railway Bureau. The full release also supports up to eight players in Time Attack, Sandbox, and Versus modes, while Classic and Endless modes cap at four. A packaged edition is distributed by Beep Japan, with a limited edition that includes a board game, an original soundtrack CD, and acrylic character stands. The Steam version will update to the full release at 2:00 AM JST on June 12. The game is priced at 3,000 yen on Steam and 3,190 yen on console stores.
The developer, Indoor Astronaut, is a Swiss studio based in Zurich composed of graduates from ETH Zurich. The original Unrailed! began development as part of a university program and was later commercialized after positive feedback. The sequel further develops the system of the first game, which was released in 2020.
New crossover character skins are available at launch. Players can use the Crewmate from Among Us, the cat from Cat Quest 3, and Tchia from Tchia.
The packaged edition from Beep Japan includes several extras. The standard packaged version comes with a reversible cover, a character sticker sheet, and a Cat Set DLC code that adds the special character "Kit the Cat" and a "Tengu Mask" hat. The limited edition adds a board game, a "Zam" & "Shuri Ken" Set DLC code (with special characters, a "Headband" hat, and a "Shuri Ken's Shuriken Bag" backpack), an original soundtrack CD, an acrylic character stand set featuring "Zam" and "Kit the Cat", and a limited edition special box. An early purchase bonus for the packaged version is an IC card sticker.
