The Necromorph Gun Arm is a grotesque fusion of organic and mechanical components, resembling a mutated limb with a built-in firearm. Its structure is asymmetrical, with pulsating veins and exposed muscle tissue intertwined with rusted metal plating and corroded mechanical parts. The arm terminates in a barrel-like appendage, oozing a viscous, dark fluid, and features sporadic glowing nodes that emit a sickly green light, hinting at its necrotic energy source. The surface is a mix of rough, scarred flesh and pitted, weathered metal, with occasional patches of cracked, chitinous growths.
