MW2 campaign is not starting

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you with your concern.

If I may ask, what is the exact error or issue that you're experiencing whenever you're trying to start the Call of Duty Modern Warfare II campaign mode so I can check that for you, Zederick?

This will determine the steps we have to perform.

Started campaign on veteran yesterday. It is very easy. A bit harder than MW2, but still easy. I have beaten every Call of Duty since COD2 on veteran, and MW2 was definitely the easiest.

Well I played the MW2 Campaign and it was REALLY easy.

I haven't played the campaign yet but i'm guessing they made it a little more difficult to complete.

If your new, start out on normal. Then make your way up to veteran.

For campaign I'd have to give it to MW1, MW2 and MW3. For Multiplayer It's MW2 and WaW.

Sorry, I thought you were talking about MP. If it's the campaign you're talking about then start with CoD4, MW2 and then MW3 if you want a cohesive story line.
