Your so close bro. That ONE star would be eating me from the inside haha. I did most of them alone on Veteran since, when you find your game hit me up and we can set a date to get it done. I need to get my copy from my girlfriends house.
I only need that ONE mission on Veteran, that's it. I've beaten it on Hardened, just not Veteran, so I'm literally missing 1 star from the 69 stars, that's how close I am. I'd be happy to help you with the others if I can find my copy of the game. Most of the rest of the missions are a piece of cake by comparison, even some of the ones with juggernauts.
So I saw on your list that you're looking to finish the Spec Ops missions from MW2. That will forever be a blight on my gamertag. I was only missing one star... the mission where you're in the airplane graveyard fighting a bunch of juggernauts. I would LOVE to go back and finish that (it's the ONLY thing I need for that game) but I'm probably too terrible at that game anymore after so long that I wouldn't be good enough to do it anyway
