Clostrophobia: Vol 1

The last clear memory is buying a VHS tape from an underground movie store run by someone whose nature was not entirely ordinary. The tape transported you into something that resembles an airduct maze — long, narrow, and structured in ways that do not match anything a building should contain. You are not alone in here. Everything inside has been oriented toward killing you, which suggests the maze was designed for a specific purpose. What that purpose is, and why you specifically are here, is the question the maze is built around.
