Graffiti Tags in Back 4 Blood are vibrant, stylized spray-painted symbols or text, often found on urban surfaces like walls, dumpsters, and abandoned vehicles. They feature bold, exaggerated lettering with sharp edges and dynamic outlines, filled with bright, contrasting colors that pop against the gritty, post-apocalyptic environment. Some tags may include additional decorative elements like drips, splatters, or character illustrations, adding to their rebellious and artistic flair.
