Kill 2000 Enemies.
Play 64-player mixed modes or 40 mans.
-This Can Be Done In Beginner Mode if you need some practice.
-This Does Count Bots But the Trackers a Little Wonky. (Bad)
-It will pop mid-match, as soon as you get it.
Its Important to Note -
This is to be done cumulatively, Not In a(One) Multiplayer Match. XD
