Any news on Firefight or other co-op modes?

I really wish I could co-op something other than story. There isn’t even scoring in campaign anymore and although I really haven’t looked, I haven’t noticed any campaign commendations. We need another co-op mode. Not just competitive playing. I like to shake things up a bit and not just do the same thing every time…I miss Firefight! A big map Firefight would be great…ones where you can actually use vehicles. Besides, my wife is kind of bummed out because she couldn’t get her money’s worth out of Halo 5. She basically just bought it for campaign, which is all of 6 hours long. We used to co-op Spartan Ops and Firefight together. She doesn’t like Slayer/ team death match-based play. She likes to co-op.
