The Harpoon Gun is a rugged, post-apocalyptic weapon with a bulky, industrial design. It features a long, metallic barrel with visible welding seams and a rusted, weathered finish, complemented by a wooden stock that shows signs of heavy use, including scratches and cracks. The gun's mechanism includes a large, hand-cranked winch for reloading, with thick, coiled rope and a sharp, barbed harpoon tip that gleams under light, suggesting recent use or maintenance.
