This Portal 2 aesthetic theme is shown in the old, condemned Aperture shafts. It is characterized by darkness, decay, and simple practicality. Chambers are built with unfinished plywood and metal scaffolding. The giant background is composed of excavated bedrock, concrete, and enrichment spheres.

Level transitions take place in metal frame elevators between enrichment spheres.
