About this game

You awaken inside a secret research facility as a subject in a disturbing psychological experiment. Guided by the mysterious voice of Mr. X, you must explore ten phobia inspired rooms and survive the trials hidden within them.
Phobophobia 1.0 The Experiment is a first person psychological horror game that blends exploration, environmental storytelling, and puzzle solving. Each room tests a different human fear while slowly revealing the truth behind the experiment.
With little guidance and growing tension, every choice feels uncertain. Do you follow the instructions of Mr. X or question the system controlling the facility?

Unravel the experiment’s disturbing narrative through hidden terminals, environmental clues, and the voice guiding you deeper into the facility. Each discovery reveals more about the experiment and your role inside it.

Solve environmental puzzles while exploring dark rooms shaped by human fears. Flickering lights, unsettling soundscapes, and limited guidance create constant tension as you search for the next way forward.

Fear builds through atmosphere, anticipation, and the unknown rather than constant jump scares. The deeper you progress into the experiment, the more reality begins to feel uncertain.
Phobophobia combines first person exploration, psychological horror, and puzzle based gameplay inside a mysterious experimental facility.
Are you ready to uncover the truth hidden in the shadows?
