Halo Reach online campaign interruptions

Halo 3 ODST.

Had the best part of Halo 3 (online multiplayer) and the Best Soundtrack, campaign, and firefight.

Reach was just utter garbage.

Were you playing the Campaign or the new Anniversary Multiplayer Map Pack?

The Campaign will show as Halo: Combat Evolved Anniversary, the Map Pack will be
Halo: Reach.

Hi,

As long as the game you're playing isn't doing anything Xbox LIVE related (not quite sure if it would work for Halo 4 since the campaign actually tracks your status online) it lets you continue the download in the background.

I was able to download some multiplayer updates for Battlefield 3 a couple days ago and play the campaign portion of the game without it interrupting the update/map pack downloads.

Just because you get the achievements for the levels does not mean you unlocked the level you wish to play. It sounds like you played in some solo and some in co-op. Which if you did co-op and solo do not combine together from my knowledge. So if you played
through til 8 solo and then co-op on mission 9 then in your solo play you would have to beat the level again in solo. Yet, you would already have the achievement for doing it with your friend. You can beat the game playing some solo and some co-op. To the
game though it thinks you have 2 separate play throughs each only partially done. Like everyone else said it sucks, but you pretty much just have to beat the level again. Make sure you play from start to finish and don't skip anything to be sure. Good Luck!

You might have to do them in order or complete the last mission fully on your own xbox. If that is the case you could use cloud or a usb to save it. does that work?
