The Black Rock Processing Machine is a massive, industrial apparatus with a brutalist design, featuring sharp, angular metal panels and exposed mechanical components. Its surface is predominantly matte black with weathered textures, showing signs of wear and tear, including scratches and dents from prolonged use. The machine has a complex network of pipes and conduits, some glowing faintly with an eerie blue light, suggesting a mysterious energy source. Central to its design is a large, circular processing chamber with heavy-duty rivets and a series of control panels featuring minimalist, utilitarian interfaces.
