A missing person investigation turned into something else when the trail revealed that the missing person had been searching for something themselves: a creature that hunts humans through tunnel systems. The investigation then produced a VHS tape from a survivor of an encounter with this entity, describing what it was like to be hunted by it. Cage-Face: Case 1 — The Mine is a short first-person survival horror game in which the player is a teenager who entered a mine tunnel to tag it with spray paint and is now being stalked through it by the creature from the tape.
