Radioactive Operators are enemies that appear in Nuclear Plant, Studios, Hangar, High Seas and Refinery. They come in two variants although there isn't any difference between them. Both versions wear protective hazmat suit and carry rod with radioactive isotope.
Though they may appear non-threatening, do not let their shambling run and weak appearance fool you, these creatures are dangerous, especially in the large groups faced in Nuclear Plant.
They have two attacks. The first is a melee swipe with their isotope rod. The other is the ability to spew out a radioactive cloud of gas. Its important to listen when fighting these enemies, as the sound of a Geiger counter ticking will be heard before the gas attack.
