The Radium Rifle is a high-detail, post-apocalyptic weapon with a retro-futuristic design, featuring a long, angular barrel and a bulky, asymmetrical body constructed from weathered metal and reinforced with rusted plating. Its surface is rough and textured, with visible scratches, dents, and patches of radioactive green glow emanating from the chamber and vents, suggesting its radioactive ammunition. The rifle includes intricate, engraved markings and a makeshift scope attached with leather straps, adding to its makeshift yet deadly appearance.
