Clarification on weekly challenges
So, i really want this weeks reward and I've done all the challenges except for the freerun race challenge. I've made several attempts, but im just terrible at that mode and am really struggling with it.
I noticed in the rewards section is says "complete any 6 challenges", so my question is could i just complete one of the zombies challenges and therefore get the 6 challenges completed i need for this week? Or do all 6 challenges have to be from the same mode?
