Firmament (video game)
2023 video game developed by Cyan Worlds

Firmament is an adventure video game developed by Cyan Worlds. Similarly to their 2016 title Obduction, it was funded by a Kickstarter campaign beginning in 2018. It was released on Windows PCs on May 18, 2023.
Gameplay
The player takes the role of a "Keeper", charged with maintaining the three "Realms" that make up the "Firmament Project": Curievale, an ice mine for fresh water to power a steam plant; Juleston, a sulphur mine and power station; and St. Andrew, a conservatory. These realms are connected by "Conveyance Pods" through a central hub known as "the Swan". The player is equipped with a Personal Maintenance Adjunct, a mechanical gauntlet that allows them to interface with sockets for opening doors and operating machines. Completing the story in each of the three Realms activates the Adjunct's upgrades: one to apply greater torque to heavier locks, one to concatenate multiple sockets, and one that increases the distance the Adjunct can access a socket.
Throughout the game, the only interaction the player has is with "the Mentor", the ghost of a deceased Keeper, who provides tips for early puzzles and backstory for the game world.
Plot
The player is awakened in a bunker in Curievale, where they are greeted by the Mentor, who explains they have awakened them from "the Threshold".
