About this game

STORY

In The Complex: Expedition, you are sent into The Complex along with your team to explore the unexplored regions. When that mission goes horribly wrong, you are left alone, dazed and lost, wandering the seemingly infinite maze of hallways of The Complex.

THE EXPERIENCE

This is a psychological horror experience based on the "Backrooms" urban legend. View the world through a VHS camera and follow along a storyline involving an expedition into The Complex.

With different endings and shifting entry points into The Complex, every playthrough can seem different. This is a slow-burning, atmospheric horror experience focused on exploration and tension.

  • Experience one of the most immersive Backrooms experiences to date.

  • Explore the mysterious and unforgiving world of The Complex.

  • Investigate an unknown lifeform residing in this world.

NOTE: This game is not connected with Kane Pixels' Backrooms nor the Backrooms Wiki/Fandom, though some parts of the experience may be inspired by them.
