The Tesla Rifle is a high-tech energy weapon with a sleek, retro-futuristic design, featuring a long, angular barrel and a bulky, boxy energy core at its center. The weapon's surface is a combination of polished metal and worn, weathered textures, with visible wiring and glowing blue energy conduits running along its length. Distinctive design elements include a series of copper coils and Tesla-style electrodes at the muzzle, which crackle with electricity when charged, and a digital ammo counter on the side. The color scheme is primarily metallic with accents of blue and copper, giving it a sci-fi yet post-apocalyptic feel.
