its pretty easy to track,if you see the person in the lead on the other team is ahead by a good amount and is in no danger of losing his spot,as it has been with quite a few games.also if i hit select see who is in the lead,then kill that person,hit select and that person is still in the lead,and i proceed to do that more than 10 times in a match,why is it not unlocking?
There has got to be some other stipulations.
Like ,it only works in certain game modes, or you have to be in the lead on your team also,or you have to do it without dieing,etc. Just for some examples.
Everyone has a different theory on how to unlock it seems. According to the description,all you have to do is kill the #1 player on the enemy team during a single game. I have done that and continue to keep doing that.Yet nothing.
I seen a video of someone unlocking it in 3v3 kill confirmed. I have played many many many 3v3 kill confirmed and have had games where i kill the enemy team leader 15-25 times while they are in the lead.And most of the time the leader had a big lead over his teamates,so it didnt flip at some point during.I have even had games where 2 people (usually split screeners)quit out,leaving 1 guy by himself until others join.I kill that person 10 times sometimes before others get into the game and yet it still didnt unlock.
So something is wrong with it or there is some hidden requirement i am not doing.
No challenge should be luck based instead of skill based. Cause if its luck,there is a chance to never unlock it, which is rediculous.If its skill,you can always work to get better at the game to earn it.
