A rectangular metal sign with sharp, clean edges, featuring a bold yellow and black color scheme typical of caution signage. The surface is slightly weathered with minor scratches and dents, suggesting it has been in place for some time within the brutalist environment of the Federal Bureau of Control. The text 'FBC CAUTION' is prominently displayed in a no-nonsense, utilitarian font, with possible additional small print detailing specific hazards. The sign is mounted on a sturdy metal pole or directly onto concrete surfaces, aligning with the game's modern surrealism and brutalist architecture aesthetic.
