The Rat King is a sleek, compact sidearm with a distinctive organic-mechanical hybrid design, featuring a matte black finish with subtle green accents that glow faintly in the dark. Its form is angular yet ergonomic, with a ribbed grip for better handling and a short, squared-off barrel. The weapon's surface is adorned with intricate, hive-like patterns that suggest its exotic nature and connection to the game's lore.
