I completed the game, a while ago, on the easiest setting. Now, how do I play again at a higher setting. I don't see it in the menu. I really want to try with regular. I mean this mainly for CODBO2. Does it appear if I try it on a different memory slot?
at menu screen for campaign, goto settings/options and then game, the Difficulty setting should be there. If not. try loading the game from the beggining. just as you start playing the first level press start and goto options/setting from there. once again, goto Game. and then you should see the Difficulty setting.
