Maze Theory is developing Project Hail Mary: Journey Among the Stars, a mixed reality game based on Andy Weir's novel. Weir wrote a new chapter for the game that appears in neither the book nor the film. Players take the role of Ryland Grace and work with the alien Rocky to repair the Hail Mary. The studio demoed the game at gamescom in Cologne, which ran August 26-30.
Maze Theory released a gameplay trailer for its VR survival adventure game Project Hail Mary: Journey Among the Stars at gamescom 2026. The game is based on Andy Weir's novel and the summer 2026 Amazon MGM Studios film starring Ryan Gosling, but features an original story written by Weir that covers an untold part of the Hail Mary mission. Players take on the role of protagonist Ryland Grace in the cockpit of the spacecraft, where they can interact with objects and operate controls with high physics accuracy. The trailer highlights the alien Rocky, who communicates through a musical language and broken machine translation, and reacts expressively to player actions. The demo lasted under five minutes and included comedic moments, but the full game reportedly includes tense survival elements beyond a simple space walk. The release date is undecided, but the game is planned for Meta Quest, PICO, and Android XR platforms, with a scheduled launch in late 2026. Wishlisting is available on the Meta store page.
