Uninvited Guest is a first-person psychological horror game set in 1930. You play as a villager who was destined to end up in an old mansion.

One day, during a rainy gray season, my beloved daughter fell seriously ill. She won’t last long without expensive and rare medicine. But, alas, we are a poor family having barely enough funds to buy food.

Fortunately, I met a collector from a big city. He was just traveling through our village and looking for someone who could pull off a delicate request: a painting, one of its kind, was hidden somewhere inside the old mansion. In exchange for the painting, the collector was offering a generous reward. I had no other options. Not wasting any minute, I mount the horse and head to the old mansion. I hope my daughter won't get worse.
