About Project Threshold

Project Threshold is a psychological horror and memory-based walking simulator about confronting your deepest fears. As a participant in an experiment, you pass through sets of blue and red doors, face what waits beyond them and try to reach the end, if escape is possible.

Remember each attempt

The game has 10 sets of doors. You choose which doors to enter, remember previous encounters, recognize patterns and learn from each attempt. There are no checkpoints: if you are caught or die, you restart from the beginning. Each run builds your knowledge and is intended to make later attempts easier.

Horror and atmosphere

Project Threshold features psychological horror elements, jumpscares, realistic visuals, atmospheric sounds and English voice-overs. Its story is told through an eerie atmosphere. A playthrough takes an estimated 30 to 60 minutes, depending on your choices and performance.
