my record is 30.000 xp (extended mag challenge IX + supressor challenge IX+ mp5k last challenge).

i dont care i just like playing 

I got 25,000 on S&D one time during double XP weekend. I completed a contract (4 kills in one round of S&D), got a 20k lifetime challange, it was a longshot headshot, and I was the last one alive on my team and it was the final kill, and it was my 10th time being showcased on the final kill cam.
