Mw3 - season 4 (How to unlock Jak intimidator)

on this challenge you can do what ever you feel comfortable you can do Multiplayer, Warzone or Plunder blood money for me it easy to do plunder blood money because its way more easy to get head shot but multiplayer it's hard for me because when you start the match you only got 2 to get clean head shot but other people can't do it so that's why
