About The Expansion

There is no escape.

You awaken in a place that should not exist.

An endless maze of empty corridors, forgotten rooms, and impossible architecture stretches endlessly in every direction. Every step takes you deeper into the unknown, where silence becomes your greatest enemy and every shadow feels alive.

Explore mysterious environments, uncover hidden secrets, solve puzzles, and survive encounters with entities that stalk the endless halls.

The deeper you venture, the more reality begins to fall apart.

The Expansion is my first solo-developed game. I spent over a year creating it, learning, improving, and bringing my vision of the Backrooms to life. Every environment, mechanic, and detail was created with passion and care.

Thank you for supporting my journey as an independent game developer. Your support helps me continue improving The Expansion and creating even more content in the future.
