The Underground Pipe is a medium-sized, straight or slightly curved tubular structure designed for transporting fluids beneath the terrain. It features a metallic, industrial look with a smooth, polished surface, often showing slight weathering or scratches from use. The pipe's ends are flanged for easy connection to other pipes or machinery, and it may have subtle color coding or labels indicating the type of fluid it carries. Its design is functional and minimalist, fitting the game's pixel-art isometric style with clean lines and simple textures.
