You step off the last train of the night at Pirámides, a long-abandoned ghost station on Buenos Aires' Line H of the Subte. When you turn back, the exit is gone. The fluorescent lights flicker over empty tiled corridors that shouldn't exist — a subterranean liminal space looping back on itself, where every wrong turn takes you deeper.
Alone in the dark, you'll need to explore every corner of the station, piece together the fragments left behind by those who came before, and solve the riddles of this place to find a way out — before whatever shares it with you reaches the platform.
