The FBC Danger Sign is a medium-sized, rectangular sign with sharp, angular edges, embodying the brutalist architecture style of the game. It features a matte black metal frame with a slightly weathered texture, surrounding a bright, luminous yellow panel that emits a faint glow, indicating its supernatural origin. The sign is adorned with bold, red stenciled letters spelling 'DANGER' and smaller FBC insignia, with subtle scratches and wear marks suggesting frequent use in hazardous areas.
