I am posting this to ask if anyone can help troubleshoot why I am unable to play the campaign online with a friend. Whenever we try to play the campaign in either Halo CE or Halo Reach, the game crashes. Any ideas? He is on Linux and I am on Windows which might be a problem, but that doesn’t seem to make sense since we are able to play custom games and firefight just fine. Please let me know if there’s something I should try to get things working.
As Linux is not a supported OS for MCC, the forums will be unable to provide help.
