"The Challenger" achievement not unlocking.

Basically what the title says. With this week’s challenges i hit the 25 completed mark and i didn’t get the achievement. Is there something else that i’m missing? Like if it has to be War Games only or did it somehow glitched?

I had same problem. It finally popped on challemge number 27. Now just waiting for last Spartan Ops episodes so I can get last 3 achievements for 1000g

Oh that’s kinda great. I guess i’ll just have to get more challenges and hope it unlocks. And yes, 3 more weeks until i get the 1K :smiley:
