The Gauss Rifle is a high-tech, energy-based weapon with a sleek, retro-futuristic design. It features a long, angular barrel with visible electromagnetic coils wrapped around it, giving it a distinctive sci-fi appearance. The body is primarily metallic with a combination of matte and glossy finishes, showcasing wear and tear consistent with the post-apocalyptic setting. The rifle includes a detailed stock and grip, often with makeshift modifications like tape or added plating, emphasizing its handcrafted yet advanced nature. The color scheme tends to be muted, with shades of gray, blue, and yellow accents, and it emits a subtle glow from the coils when charged.
