when you're wandering around in refinery, you noticed a Helghast soldier doing push the button open the lift. Then, a Helghast Heavy Trooper named Arc Trooper appeared with his electricity gun. He shot his electricity gun, then prepared to fight with you. But you hide behind the container. He was looking for you, and found you right away, then he shot his electricity gun at you

I can see you~ Hahahahahaha!!!
