The Hat Man: Shadow Ward is an indie horror game by Game Mechanics. The developers state that the game is based on the true story.
Plot
Your daughter is diagnosed with dementia and is put in the Canton State Insane Asylum. Sometime later, you receive a letter from the asylum staff that she has gone missing from the Asylum. You set out to find her. Upon the protagonist's arrival, everything goes to hell. Electricity and communication with the outside world get cut off, and supernatural events occur. You have to get out of there.
Gameplay
The game's controls are usual for the first-person experience. WASD is used for moving, Q and E for leaning, with spacebar to jump and I bound for your inventory. There are no usable weapons present in the game. The only things the players often use are a flashlight, medkits, and some matches. One time in the game the players can use a fire ax to break a door, yet this event is completely scripted.
The premise of the gameplay is simple: avoid the mysterious Hat Man and the Shadow People that are encountered on your way out of the asylum. The game puts a heavy emphasis on using light sources to see your enemies. It is impossible to attack the enemies, as the players don't have any weapons at their disposal, so the only thing the players can do is to run away from the creepy creatures.
