Gamepia (CEO Jeong Jong-heon) announced that 'Stepper Retro: Supernatural Mystery Quest,' currently in development by Team Tetrapod, will be released on Thursday, July 23, 2026. The company also launched a preview page for the game on Tumblbug. The title is being developed for PC (Steam) and Nintendo Switch™.

Founded as a four-person team in 2023, Team Tetrapod has consistently expanded its 'Stepper' mystery adventure series. The team has since grown to nine members, leading to the development of 'Stepper Retro: Supernatural Mystery Quest,' which opens the second act of the series' universe. Launching this July, the game features over 30 hours of gameplay, multiple endings based on player choices, and a document-based deduction system.

This new installment marks a significant expansion for the series, featuring a simultaneous Nintendo Switch release, Japanese voice acting, and full Spine animation, promising more immersive production and content than previous titles.

Through this release, Team Tetrapod aims to introduce the series' signature mystery mechanics and world-building to a wider audience and use the global launch as a springboard to accelerate the expansion of the 'Stepper' franchise.

Meanwhile, the Tumblbug project is more than just a sale of commemorative items; it is a crowdfunding campaign for merchandise spanning the entire 'Stepper' series. The goal is to express gratitude to long-time fans and collaborate with them on the next phase of the series' growth alongside the new release.

Rewards range from digital items to physical merchandise, art books, and music boxes, all designed to let fans experience the world and atmosphere of the 'Stepper' series beyond the game. Featured merchandise includes sticker sets, metal badge sets, double-sided acrylic keychains of characters 'Verita' and 'Bering,' a 'Verita' scarf, layered paper frames, a limited-edition hardcover art book, and a music box version of 'Tabaco Smog,' a track used in key scenes of 'Stepper Case.' These items were curated to allow fans to continue enjoying the game's world in reality.

The project also includes various stretch goals. These focus on expanding the series as a whole, with milestones for new content, additional production elements, epilogues, vocal music videos, plans for spin-offs and sequels, and Korean voice dubbing. The stretch goals are designed to provide tangible content expansions that backers can directly experience.

Additionally, free demos for both 'Stepper Case' and 'Stepper Retro' are available on Steam, allowing players to experience the atmosphere and core gameplay of the series firsthand.

Team Tetrapod stated, "This project is a way to celebrate the 3rd anniversary of 'Stepper Case' and the global launch of 'Stepper Retro' with our fans, as well as a starting point for building the future of the series together. We hope to thank the fans who have been with us from the beginning and introduce the charm of the 'Stepper' series to a broader audience."
