I completed all episodes of Chapter 1 on normal and it didn’t award me. It initially showed that I didn’t complete Chapters 2 or 3, but updated to say they were finished after I left Spartan OPs and reopened it. Waypoint still says I’ve only completed 3/5.
-Yoink- Chapter 3 too, that -Yoink- is overwhelming.
I completed all Chapters of Episode 1*
i’ve got the achi but not the challenge completed 
Dedicated to Crimson
Complete all chapters in the first 5 episodes of Spartan Ops on any difficulty.
Episode 1 is the only episode currently available, the others will be released on a weekly basis.
Well derp I guess I misread it. Thanks.
