Your rescue team has been called up as a matter of urgency from Tokyo to a quiet mining town. A group of miners hasn’t returned from the rock masses after one of the shifts. A local group of rescuers went down to carry out the search operation. Communication with this group was interrupted almost immediately. Not a single person came on the radio after half an hour, after an hour, after three hours… Most evidently, they also need your help. What’s going on? No damage has been detected. Everything seems to be in order: the elevator, the changing room, the tunnels… Dismal silence is the only factor raising concern. There came a sudden rustling! A shadow slipped past… Someone sneaked up behind you. Strange sounds, moaning. A dark silhouette. Miner? Rescuer? He is approaching you. Oh my gosh!!!! No way! What the hell!.. Demons!
