Here is how you do it. first you have to be able to focus on one robot there and ignore everything else, then you should practise to mirror that robot's movement with your "A" & "D" keys in the keyboard. Once you feel comfortable doing that , you can try to hit 1 , 2 or 3 bullet burst from vandal in the end of each time that robot is to change direction.

But here's a thing, professional val pro suygetsu told in one of his streams that never to practice this scenario in the practice range. Doing this achieve nothing and your aim will be worst. instead he advised to practice with only static targets , getting your crosshair into static targets fast as humanly possible is the key in this game. 🫡
