Project Threshold is a first-person psychological horror game developed by Murushii Studios and Kyronaught Games. The player becomes a participant in an experiment created to expose people to their deepest fears. Inside the facility, every stage presents two doors, one blue and one red. Choosing a door leads to a new trial, while reaching the end requires surviving what waits behind all ten sets. The game was released on Steam on June 25, 2026.
Each threshold presents a decision without fully explaining the consequences. One door may lead to a disturbing environment, a chase, a sudden scare, or another situation connected to a specific fear. Players must explore the selected area, understand its danger, and find a way to continue. The atmosphere is supported by realistic visuals, English voice acting, environmental sound, flashing effects, and psychological horror elements.
Project Threshold is structured around memory rather than permanent upgrades. There are no checkpoints, so dying or being caught returns the player to the beginning. Information learned during one attempt becomes useful during the next, making repeated runs part of the intended progression.
To complete the experiment, players need to:
A successful run depends less on collecting equipment and more on remembering which choices created danger. Every attempt helps the player build a mental route through the experiment.
The controls follow a standard first-person walking simulator structure, with keyboard movement, mouse camera control, and interaction with doors or objects. There are no traditional numbered levels, combat builds, or character statistics. The ten door sets act as the main stages, while the player’s choices and performance affect how long completion takes. The developers estimate that one playthrough lasts around 30 to 60 minutes.
Project Threshold is designed as a short single-player horror experience in which failure is expected. The main objective is to learn from each run, remember the dangers hidden behind previous doors, and eventually escape the experiment. Its content includes loud sounds, blood, disturbing imagery, intense jump scares, flashing lights, and scenes based on different phobias.
