Firmament is a single-player puzzle-adventure set in a seemingly abandoned world, where exploration gradually exposes the purpose behind its strange places and machines. Its steampunk aesthetic and emphasis on deep storytelling frame the journey as an unfolding mystery: the player encounters three Realms, each with secrets to uncover, while a mysterious apparition offers a story of her own.
Puzzles revolve around the Adjunct, a carried device used to interact with mechanisms throughout the Realms. Solving them brings the player closer to the world’s hidden history, linking hands-on interaction with questions about the gigantic machines, the Realms’ purpose, and whether the accompanying spirit can be trusted. Rather than presenting its setting as scenery alone, Firmament makes discovery and problem-solving central to how its narrative is revealed.
The game supports both 2D displays and VR, with free-roam and teleport movement options in VR, alongside comfort settings such as smooth or snap turning.
