I'm incredibly pissed with the Special Operations achievement. A friend of mine and I sat for close to 8 hours doing every map on every mode, it didn't unlock, and come to find out, it's glitched, so it gives it out randomly. Needless to say we weren't happy.[/quote]
Did you try deleting the red and black map packs? I ran through all the games and it didn't unlock, so we deleted both map packs out, and the next game we played it unlocked the achievement.
