UMP-45 | K.O. Factory
Drawn from the Fever Case and The Fever Collection, the UMP-45 K.O. Factory is a Classified SMG skin whose design takes clear inspiration from old animation cartoons, lending the weapon a lively, exaggerated visual identity. The UMP-45 is a versatile close-quarters automatic, and this finish transforms it into something visually playful. Its float range runs the full 0.00 to 1.00 spectrum, so examples at higher floats will display significant wear across the cartoon-styled surfaces. StatTrak availability is confirmed.
