The FBC Cryogenic Sign is a medium-sized, rectangular metal plaque with sharp, clean edges, embodying the brutalist architecture aesthetic of the game. Its surface features a slightly weathered texture, with a matte black finish that contrasts with the bright, luminous blue cryogenic symbols and text, giving it a modern surreal look. The sign is asymmetrically designed with raised, angular lettering and symbols that appear to glow, suggesting its importance in a high-tech, paranormal environment.
