His screen credits also include Game of Thrones and Doctor Who. In Sublustrum, he takes on the role of the Professor — a central figure in the game’s story. His recordings guide the player deeper into the world of Sublustrum. You’ll be able to hear Nicholas Boulton in the Open Playtest from October 12 to 25, featuring Chapter One of the game.

The longer you study the details, the stronger the feeling grows: these are not decorations. These are objects with a history not meant to be told aloud. And when the music surrounds them, it does not sound like background. It sounds like a witness. #sublustrum

In Sublustrum, things may be silent, but they are never empty. Wood retains the warmth of other hands. And mechanisms remember the purpose for which they were last set in motion. The only question is whether one would wish to start it again. #sublustrum

Light is no help in these places. It only reveals more details. And the closer you look, the less you want to take the next step. Not out of fear — but out of understanding: what lies ahead is not an answer, but another mystery. #sublustrum

Some objects look too ordinary to raise suspicion. But linger on them for a second longer, and you sense they are not here just for decoration. In Sublustrum, objects don’t merely shape the interior—they capture a moment. #sublustrum

There are places where music does not entertain—it warns. You don’t realize it at once: first you catch the rhythm, then you you notice that silence can feel heavier than any sound. Sublustrum knows how to leave traces like these. #sublustrum

Ancient idols remain silent. The civilization that created them has long since disappeared. What became of those people? Did they fade away, dissolve into the current of time? Or did they simply leave a world that was not yet ready to accept—or understand—the scale of their designs? #sublustrum

The echo of the scientist’s footsteps no longer lingers in this room. But his notes, books, and journals remain. And his voice may yet shed light on the mystery of his disappearance. #sublustrum

Giant flywheels, brass gears, steam engines… Sublustrum captures the spirit of early 20th-century retro-engineering – an era of bold experiments with mechanics. Take the ship-stabilizing gyroscope, for example: a massive rotating flywheel that once kept vessels steady by counteracting roll and balancing motion. Over time, these anti-rolling gyros were replaced by lighter hydrodynamic stabilizers. Yet their aesthetics – huge spinning wheels, heavy housings, and brass fittings – preserve the veiled atmosphere of vintage machinery within Sublustrum. #Sublustrum #RetroEngineering
