Question: Co-op campaign

I currently need the achievement for completing the entire campaign in co-op mode.

Can you find people to do this with via matchmaking or do you need to arrange a private co-op game over x-box live?

I tried matchmaking but it didn’t find anyone. Is it because of a low on-line population?

I thought with the recent reduction in dlc prices more people would have been playing this again.

Thanks for any answers in advance.

I also need that achievement, and I don’t think you can matchmake a campaign mission because when I try it it just says waiting for other player instead of searching… I think you can only do it with invites.

Send me a Friend Request if you want to do HaloWars co-op or versus. I can use a few more achievements.

Great, I’ll send you a Friend Request on Live and we’ll do the campaign co-op together.
