The Roach Warren is a Zerg structure with an organic, asymmetrical design, resembling a living, breathing organism. Its surface is covered in a rough, fleshy texture with pulsating veins and bioluminescent patches that emit a faint glow. The structure features multiple bulbous protrusions and spiracles that open and close rhythmically, indicating its biological function. The color palette is dominated by deep purples and reds, with highlights of green and blue from the glowing sections. The base is anchored by tendril-like roots that dig into the terrain, blending seamlessly with the Zerg creep.
