Our take on experiment: one

The short runtime concentrates the experience on one night shift and its calls, but limits the time available for extended story development or exploration.

What is experiment: one?

This psychological horror game casts players as Evelyn, who works at a helpline.

When her boss asks her to cover the night shift, she faces a long night in the office and a series of strange events. Players respond to calls through a dialogue system, and their choices affect the ending. The story places the caller’s life in the player’s hands, with the possibility of saving or killing the person on the other end. Presented as a first-person walking simulator, the game pairs quiet horror with moments of greater tension. The stated average completion time is 90 minutes. The vendor warns that flashing images may trigger seizures in some people with sensitivity to light and recommends restricting the game’s audience.
