An isometric underground bunker cut open to show rooms, storage bays and control panels, floating as a tile above a dark background. Glowing cyan square frames and a recessed brick-rimmed pit hide the finder squares, while corridors, crates and consoles carry the dark and light modules. Warm orange stripes and tan walls sit against deep shadow, so the pattern keeps strong contrast across the whole floor plan. A glowing blue tower hovers at the right edge.
