Underground (Portal 2)

Abandoned

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.

This theme is the third theme and the sixth and seventh chapter of the game. There is a complete change in the environment. It is a cold and dark place, with mold, water, and broken walls. Pre-Recorded Messages are placed in the test chamber to introduce the player to the test. As the player advances through each test chamber, the tests become more destroyed. The campaign uses this theme for: Plot Advancement Introduction of Mobility Gels
