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 barrel's tip, which crackle with electricity when charged, and a matte black grip for handling. The color scheme is primarily metallic with accents of vibrant blue from the energy components, giving it a luminous, high-tech appearance amidst its post-apocalyptic wear.
