An update that is a long time coming is finally about to arrive in the next patch for Call of Duty: Modern Warfare. According to production director on Call of Duty: Modern Warfare, Paul Haile, there will be an update released tomorrow that will give players more install options.
Specifically, this update will have "mode specific uninstall options" for Modern Warfare. This will be for PC players only, however. There is no word on whether or not this feature will make its way to other platforms or not. This update seems to be a real necessity given that the game reportedly no longer fits on a 250GB SSD.

Doesn't seem very intuitive however, you can uninstall "packs" so deleting Campaign Pack 1 and 2 would in theory remove all the campaign?
I don't know, it's something at least, maybe it'll be a bit less weird on PC.
