This game is almost unplayable for me now. Everytime I play multiplayer (sometimes happens in campaign to) the game freezes after 40 min- 1 hour 30 min. I usually play a game for 2 hours, sometimes more. It freezes in the middle of a game, no disc read error, it just hangs there and I have to restart my 360. I have tried installing it to the Hard Drive and this has not helped either.
