About this game

THE EXPANSION – A Backrooms Experience

You weren't supposed to end up here.

One moment everything was normal. The next, you find yourself trapped inside an endless maze of yellow walls, buzzing fluorescent lights, empty hallways, and places that shouldn't exist.

But you're not alone.

THE EXPANSION is a first-person psychological horror experience inspired by the unsettling atmosphere of the Backrooms. Explore strange environments, uncover new areas, and survive the entities hiding within them.

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.
