Stray Souls is a psychological horror game that each playthrough will bring something new to the player, since the appearance of the paranormal occurs randomly. In addition, there are quite a lot of dialogues, during which the gamer can choose different lines that influence future events. The story has many branches and can be played through several times.

Daniel is an ordinary teenager who for the first time has to face the inexplicable and supernatural. His grandmother died of old age and bequeathed her house to her grandson. The mansion is very old and, moreover, is located somewhere on the outskirts of the suburbs, so the guy decides to go there to inspect the condition of the square and estimate its approximate cost. In a small settlement, he meets an unusual girl named Martha, who seems to know a lot about this place. She recommends that he not stay there overnight, but the protagonist chalks it up to stupid rumors and still stays overnight. But after the sun has set, he realizes that he should not have disobeyed his new acquaintance.

The Stray Souls house is inhabited by a huge number of evil spirits and demons that will attack the guy. He needs to understand why they appeared here and how it is connected with the deceased granny. He can fight off creatures with anything, be it a suddenly found pistol or a chair, breaking it on the enemy and stunning him for a short period.
