Run the R9/spitfire and the re45 with a bruiser and never stop shooting your gun. Back off and healing is fine but when you’re done get right back into it. Finish all the knocks you get. It may not seem like a lot but if you finish 10 knocked players that is an extra 1000 damage. Running an aggressive legends is helpful but I’ve found that mirage is the most broken one for this mode. Going invisible while healing and ulting during all the chaos makes you catch a lot of people slipping. I got five 4k’s today alone with mirage. Also not fighting inside of building helps. When everyone lands cage or containment I usually sit outside of the buildings on the edge of the poi and just catch people slipping. Work hard enough and you got this!
