How to delete the MW3 campaign

Get the campaign out of the way first. It is more than likely you really only got the game for the online capabilities anyway. Once you have finished the campaign, you can then selectively delete it while still having full access to the rest of the game. You only need to keep the bits you play. Activision knows how obscene the file sizes are and is trying to mitigate the blow.

In COD HQ

In Call Of Duty’s own launcher, you can delete the campaign and easily manage MW3’s files. Simply Open COD HQ, navigate to the side panel and head down to Settings. Here you need to scroll down to manage files, where you will be able to view all the parts of the game you want to keep and cull.
