Replay the map detox center over and over
+Use the vulcan t6 fully upgraded
+ rush through the map as fast as possible
+ If done at a good pace you can get 125 kills every 2.5 minutes
+ 1250 kills per 25 minutes if done perfectly

+ if you do long biohazard that gives 194 kills per 10 minutes. But if you do dtox center you
can get 625 in 12.5 minutes or less. Basically 3x the amount of kills in close to the same time.

+ If you were to do survival you can get 90 ish kills within 3 minutes. But this method still puts that strategy to shame.

+ This method from 5000 kills to 10k takes 1.6 hours. You would have to replay this map about 40 times and if you do it within the time shown in the screenshot below. You can complete this in under 2 hours.
+ Make sure you got autoheal and put the difficulty to easy in gameplay options to maximize kills.
