Developed by Cyan Worlds Inc, Firmament arrives today for Windows and Mac on Steam and GOG, verified for use with the Steam Deck. Music for the game is composed by Maclaine Diemer.

Funded through a successful Kickstarter campaign, Firmament employs a unique steampunk aesthetic to distinguish its seemingly abandoned world. Players are invited to explore the spacious environs, joined by a mysterious apparition. Employing a device called “Adjunct,” players can interact with giant, mysterious machines, solve puzzles, and unlock mysteries.

The puzzle-adventure game with monitor and VR compatibility will launch for Windows and MacOS operating systems. Firmament supports Valve Index, HTC Vive, Oculus Rift, Rift S, and Quest 2 headsets via Oculus Link. PS4, PlayStation 5 and PlayStation VR 2 ports are currently in development.

Firmament Original Soundtrack debuts today, via Bandcamp and Steam. The 21-track score is available for streaming on Amazon Music Unlimited, Spotify, and YouTube Music. The launch trailer features "Collide" by the VNV Nation electronic music project led by Ronan Harris.


From the product page:

Featuring a unique steampunk aesthetic, Firmament invites you to explore the legendary deep world-building Cyan Worlds is known for. Firmament is a fantastic visual feast, with thrilling new sights to see around every corner. At the same time, the world of Firmament feels completely plausible; as though it were constructed with a bigger purpose in mind… A purpose you will be compelled to discover as you play.

You carry with you a device called an “Adjunct” as you explore. This Adjunct is your interface as you interact with the various devices throughout the Realms of Firmament. Employing the Adjunct to solve the puzzles you encounter will bring you ever closer to unlocking the secrets this place holds.
