Need help with co-op game (1 house, 2 xboxes with Halo)...

[davidwilkie]

I am having trouble setting up a co-op campaign in my house. Specifically, every time I re-start the campaign, it makes us start at the very beginning again. In other words, all progress is lost.

 

Here's our setup:

 

2 xbox consoles

2 Halo 4 discs

3 users (all with free Live accounts)...note: one of the users (Dad, that's me) is nearly through the game

setup each Xbox Halo for "LAN"

 

I login on one Xbox and my two sons login on the other Xbox. I'd like to have one "campaign" that progresses with all three of us together. In other words, when we three create the next co-op session, it picks up where we three last left off. I do not want our co-op to pick up where I last left off in my solo campaign, nor do I want to restart at the very beginning again.

 

So, how do we set up a 3-player co-op campaign that we can return to at the same point we left off? Please be as specific as possible and assume we know very little about setting up multi-player co-op games (which is true!).

 

Thanks for any help!
