Can’t seem to play anything on halo 4. Don’t know what the problem is but ill start a search for a game, it’ll get as far as voting for a map then before the game starts it restarts the search and tells me everyone in the game left. Last week I was in a party with a friend who lives literally around the corner from my house and I’d get booted from the party/game and he would be allowed to continue. Jut tried playing campaign to see if it was just matchmaking and it’s saying I don’t have the right downloadable content. Um what? It’s just seems to be an endless cycle of problems with matchmaking and I’m really starting to get sick of it. I paid good money for this game and now all I can use it as is a drink coaster.
Not sure why you can’t play Campaign, but I think your maps got corrupted. Go onto your HDD and delete them alomg with the Spartan Ops ones, then redownload them using the second disk that came with Halo 4.
