343 has said that Spartan Ops takes place after the Campaign. And in Spartan Ops footage, we see Crimson Team fighting Sangheili, Unggoy, and Kig-Yar. So this means that we’ll be in conflict with the Covenant at that point again. Do you still want to fight them by the end? I mean wouldn’t the Covenant after probably learning many secrets about the Forerunners in this game would be like, “They’re not who we thought they were…”
There not exactly the covenant, more of a rebel faction.
I think the forerunners will lie to them and take advantage of their blind idiocy.
