MM maps semi accessible in Campaign

Hello, I had a interesting idea. What if you could access a multiplayer map while playing campaign? Maybe run through them for an objective, just passing through, or the setting of an cinematic trailer.

I feel it’d be fun to practise or play against AI in this way.

What do you think?

Like Reach?

I might be shaking a hornets nest here, but I didn’t mind Reach where all of the maps came from campaign

Well…it would be pretty cool to have them in the campaign. Or, better idea yet, just bring back Spartan Ops from Halo 4 and have them in there.
