Mannequin Syndrome is a first-person survival horror game for solo play or 1–4 players in online co-op.
You are sent into the Syntrax Facility, where something has already gone terribly wrong. The building is still running, but not the way it should. Some systems remain active, some areas still function, and throughout the facility mannequins stand motionless like empty shells.
The active mannequin does not always stay the same. At any moment, the one hunting you can become still, while another somewhere else becomes active. That means every mannequin in the facility can become the threat.
Your objective is simple on paper: enter the facility, restore critical systems, complete the required objectives, reach the shutdown sequence, and escape.
The deeper you go, the worse the situation becomes. Every completed objective moves you closer to escape, but it also makes the threat more dangerous. What begins as something slow and unsettling becomes faster, more aggressive, and far less predictable.
The challenge is not only staying alive, but continuing to progress. Exploration, objectives, and coordination become harder as the threat escalates. To survive, you will need to restore access, open new paths, interact with terminals, solve puzzles, and keep moving forward under pressure.
The mannequins are not there just for atmosphere. They are the main threat. As the round progresses, they become more relentless, more dangerous, and harder to read. Once the endgame begins, the facility stops feeling like a place you are exploring.
