You was walking in an old building with your friends to make some urbex, it was an old laboratory where the inside was in ruin, the wall was broken the windows too, she furnitures almost ruined and plants had grow back inside, there is a light smell of old blood, dust and darkness, the place is dark. Then you and your friends deside to spread them all over the building, and you are now alone...and you can hear some sounds...like growlings of a wolf...should you go to and check?
