The Overseer's Guardian is a high-powered combat rifle with a distinctive two-shot legendary effect, featuring a robust, utilitarian design typical of Fallout's retro-futuristic aesthetic. Its body is primarily constructed from weathered metal with a matte black finish, accented by wooden grips and stock that show signs of wear and use. The rifle includes a long barrel with a reinforced muzzle brake, a detailed iron sight, and a scope attachment option, showcasing intricate engravings and serial numbers that hint at its pre-war origins and subsequent modifications in the wasteland.
