Special Operations Achievment Help

[Frozen Bodies]

hey i know this sounds stupid, but ive heard rumors that this achievment may be glitched or messed up or whatever...i have a list of all the maps that need to be played for every game mode. i checked them off the list as i went. when i did not get the achievment, i played all of the new maps on every game mode. the only game modes i havent done every map on are the new game modes. any advice besides playing all of them on the new gamemodes?

It is glitched. I was doing all the maps and game modes with a friend one day. Three maps later he got the achievement, and said that he shouldn't have because he was still missing like 8 maps and 4 game modes.

I've done nearly all of them that I know of, I'd say survival or retrieval is what I don't have. It's ghey.

yeah so i dont know why or how its glitched, but i ended up getting it after playing a 20 min attack and defend match at calypso casino of all places...which is what i always used to play when i first got the game. thanks for the help...wish the achievements along with everything else werent so glitchy.
