Our take on The Sleep Experiment

The defining structure is a first-person descent through increasingly disturbing environments while prolonged wakefulness causes the test subject’s perception and sanity to unravel.

What is The Sleep Experiment?

Step into the role of a captive participant at a classified Soviet laboratory, where prolonged wakefulness and horrifying stimuli test the limits of the mind.

This first-person psychological horror game uses surreal visuals and a sequence of progressively disturbing settings. As exhaustion erodes perception, threats grow difficult to separate from personal fears. The journey brings encounters with unstable fellow participants and the researchers behind the trial. Survival depends on preserving sanity while investigating the experiment and confronting buried inner fears before madness takes control.
