Ruined Facility for People Playground

This is best played with floodlights off.

You are a test subject at a facility, you get put into a medically induced coma, after that, a tragedy happens and the hallways collapse on themselves, the ventilation system is all that remains. After you wake up you lose all your memories, but are still somehow alive. Something lurks in the vents. There are rotting skeletons everywhere. Damn that.. What was his name?
